Patient Reviews





August 2017

Thank you to Dr. Helfner and staff for being flexible enough to see my daughter for her checkup and complete her required fillings before she left NY for college in Florida in early August. It’s a great relief to know that her teeth are healthy and she will not have to worry about them while she is starting school! Also, I greatly appreciate the effort you made to work closely with her oral surgeon in July when her wisdom teeth were removed to make sure her anesthesia was correct to make sure she did not have any allergic reaction.

Friendly professional office

The staff is very nice and professional! They always make you feel so welcome when you walk in. The office is very clean. Dr. Helfner and the rest of the staff are very nice and take the time to really teach you and especially the children how to properly take care of your teeth! My kids love going there and so do I 




May 2017
My 11 year old needed a baby tooth pulled and Dr Helfner and her staff could not have been more gentle and caring towards her during the entire process. They reassured her throughout the procedure and took the utmost care of her. The staff was so loving to my daughter once she was done and made her feel so relaxed and special. I could not ask for a better dentist than Dr. Helfner for my family. She’s hands down the best!
-L. Nevins 
Dr. Helfner spent time with me and was honest in her recommendations. I would highly recommend her! The office staff is friendly and accommodating. 
-C. Edelstein
I have been going to Dr. Bonnie Helfner for the past 20 years, and by far, she is the best dentist I’ve ever had! She is an excellent dentist and has a very thorough approach. She is extremely caring, kind, considerate, and very familiar with all of the latest computer-based dental technology. The team at Dr. Helfner’s office is outstanding. Doreen always makes me feel comfortable in the chair, and 
Kim creates a warm and welcoming environment in the office. Upon entering the state-of-the-art office, you are met with a smile by Lori, Kerrie, Dawn, Rosa and Kelly, who possess warm and friendly demeanors. I’ve had cleanings by all 3 hygienists, Helen, Sarah & Allison, and each one is caring and very sensitive to my needs. From cleanings to crowns, from veneers to implants, I’ve had it all done in Dr. Helfner’s office, and I highly recommend her as your next dentist.

 I have had two visits. The first, a cleaning and comprehensive exam. The second, 3 fillings for caries found during the initial consultation. Both visits were extremely thorough, pain-free and educational. I’m extremely impressed by the dental care and very grateful for how billing matters are handled as there are no surprises as to costs. I look forward to my next cleaning in October 🙂
– S. Fairchild

When I arrived for my appointment I was given a tour of Dr. Helfner’s beautiful office and introduced to her staff. I was brought into the exam room without waiting. Dr. Helfner explained my treatment plan. She showed me pictures of my mouth explaining what will need to be done. My cleaning and exam was thorough and painless.

Today was my first visit, I was taken as a emergency patient. The very clean office was nice and the staff was great. Professional, friendly all the things you need when your in pain. Dr.Helfner was very nice and explained my issue in detail. I would recommend this office. The salt water tank in the waiting room was quite impressive.                            
 –AnnMarie A. 
I was very impressed on my first visit. Everything was explained clearly to me as to what were my issues and what had to be done to correct them. Everyone is extremely friendly and makes you feel comfortable. The office is immaculate.

“Well organized, so clean, friendliest staff that I’ve ever met, kid friendly. Most thorough cleaning and exam that I’ve ever had. They explained every detail of the dental work that I need and every option. My 10 year old wasn’t frightened at all. She loved them all.” 
-D. E.
“After having a not-so-great experience at another dentist, it is a big relief to find such kind and competent professionals. Everyone is very friendly and knowledgeable. Dr. Curro took the time to explain my treatment plan, and I’m so happy to know I will finally be getting the work and care that has been long-delayed. As many have mentioned, I will also be bringing my daughter to this practice! Thank you so much.”
-Kathy F.
“Bonnie Helfner has the best dental practice I have encountered. The staff is friendly and informative. Bonnie is a brilliant dentist with a fantastic bedside manner. Helen is a great hygienist and you leave knowing you received a thorough cleaning. I have recommended Bonnie to many and will continue to do so.”

January 2017
I always hated going to the dentist. In fact, I avoided it for years. Now that I have found Dr. Helfner’s office, most of my fears and dislike of dentist visits have dissipated. Dr. Helfner speaks with me openly and honestly. She respects my wishes and never tries to coerce or scare me into doing more work on my teeth than I am ready for; unlike so many other dentists I have been to in the past. Any work on my teeth has always been quick and relatively painless. I have truly come to trust her! Now I visit the office every three months to prevent gum decay. The hygienists are excellent and always do a thorough job. I watch my choice of tv or listen to my choice of music on headphones they provide. And I love that it is an all female office! The staff is professional yet very friendly. The office itself is state of the art, very clean and nicely decorated. I love the beautiful salt water fish tank in the waiting room which is also spotless and filled with lots of healthy specimens that I have seen grow over time. Just more evidence of how caring they are. A couple of years ago, I transferred all three of my children from a pediatric dentist to Doctor Helfner’s practice. I am much more satisfied with their care and my kids are happier as well. I never have to wait long and the girls behind the desk take care of all the insurance billing. Nice and easy. I highly recommend Dr. Helfner for your whole family. Even my husband loves her!  
-Pamela V. 
I have been seeing Dr. Helfner for over 15 years and I will never go anywhere else. Her staff are amazing, polite, knowledgeable, caring and excellent at what they do. Their offices are out of a design book, state of the art finishes and technology and Dr. Helfner is just awesome as a Dentist, she really cares about her patients. I recommend them often! 
-Teresa V.
What a great experience. I’ve never been there before. Had an emergency and they were able to take me by the luck of the draw 15 minutes later at the end of the day yesterday. Treatment was thorough, educational and quick!!! To top it off, I got a call at 8pm that night to see if I was doing ok. Can’t recommend them enough!! A great experience.

December 2016

Dr. Helfner and her staff are top notch! I had an emergency and they were so accommodating! They were able to fit me into Dr. Helfner’s schedule that day and were beyond nice upon my arrival. Will definitely be switching my family over to Dr. Helfner.
-Michelle G.
Today was my first time visiting this office for a cleaning. The receptionist who greeted me was cheerful and offered a tour of the office as well as complimentary beverages. The Dental Assistant and Dentist made me feel so comfortable, kept me informed, and went above and beyond to answer all my questions. I would recommend this place to anyone and everyone – if only every business could be like them!  
-Ashley C.
As always, the experience was great. My scheduled apt was confirmed on line and via text and all of the staff was extremely professional. I would highly recommend the practice to anyone considering a move!
-Barry G.

November 2016

Bonnie Helfner’s office staff is kind, courteous, and professional. The dental hygenists are gentle and conscientious regarding my nervousness and anxiety with dental work. Dr. Bonnie Helfner and Dr. Kristin Curro provide excellent care in a comfortable and relaxed manner. I highly recommend this office for any dental needs. 
-Karen T.
My daughter had her periodic cleaning scheduled. Took her in right on time. All went well. Also, they noticed I had an upcoming appointment for a cleaning later that week. They had an opening and fit me in at the same time. Converted my waiting time into something productive. Thus saving me a separate trip. These guys are the best!
-Mario A.

September 2016

From the moment you walk in till leaving. The staff couldn’t be nicer or more helpful. The hygienist’s are amazing so thorough. Dr. Helfner explained everything she was doing. And made suggestions as if it was her own teeth. I have had 3 great experiences.

-Doreen M

Dr. Helfner is a superior dentist. I’m a bit of a nervous patient because of past experiences I’ve had prior to coming to this practice. But here I always leave feeling that every concern was addressed & resolved with knowledge & compassion. It’s quite comforting. The office staff is incredible too.

-Dawn M

The entire staff is professional and courteous. In addition to being a highly skilled dentist, Dr. Helfner’s level of care and concern for her patients is unparalleled. I highly recommend this practice.

I have been a very satisfied patient at Dr. Helfner’s office for many years. I’ve come to expect the outstanding personalized care of the doctor and her clinical team, the professionalism and smiles from the front office staff, as well as the overall comfort of my experience, including the attractiveness of the office itself. Love that salt water fish tank in the waiting room!

-Mike G

Always a bittersweet experience. I mean who likes the torture of a dentist? But their office makes the experience as pleasurable as possible. From the front desk to the back office to the practitioners, they are all extremely personable and very skilled. Great office overall, which is very difficult to find!


I can’t say enough good things about this office. From the moment you walk through the door to the moment you leave, the staff is fabulous!!!

The people here are incredible. I am a very anxious patient and they make me feel comfortable and don’t get frustrated with me. Highly recommend it.


July 2016

Team Helfner are a well organized group of professionals ready to make their clients feel comfortable, welcome, and cared for. From Kim at the front desk to Dr Curro, and everyone in between … they were great!!! I felt safe and at ease in the exam room. The assistant was professional and engaging making the x-rays fly by. The Dr made clear recommendations and happily answered my many questions.

-Maureen H

-Andrew K

Bonnie Helfner, DDS, is the best dentist and she has the best dental office!! Her associate and her hygienists and her entire staff is professional and compassionate. They go out of their way to make sure your individual needs are met from the moment you walk into the office.

May 2016

Everyone is just great. From reception to cleanings to dental work, everything is run smoothly, and for me, painless. Thanks for another terrific visit.


I was very impressed with this office and my son was very happy as well. The staff was so awesome from the moment we walked through the door till the minute we left. I can’t wait for MY cleaning appointment!


Dr. Helfner and her staff are phenomenal. The facility is fantastic as well!


April 2016

Great office. Clean, updated equipment. My hygienist Sarah was very knowledgeable and made me feel comfortable. She took her time to explain things to me. Same for Dr. Curro.


Dr. Helfner and her staff are awesome as always. I had to schedule an early evening appointment before I headed out of town and they were able to accommodate me. I’m very happy that my family and I came over to Dr. Helfner’s practice. More important even than the state of the art equipment is the personal touch and care they provide to patients.


The staff is excellent, they all know your name and are very warm and friendly. The cleanliness of the building is nothing like I have ever seen and I get to watch TV as I get my teeth cleaned. The best staff I have ever had at a dentist office.


March 2016

No one likes going to the dentist. But. This place is the best. They care. They make you feel like you matter. Everyone i as nice as can be Very friendly.


I am new to the practice and saw Dr. Curro for somewhat of an emergency. The staff was accommodating and kind and Dr. Curro is very professional.

February 2016

Very thorough and super accommodating. Extremely clean and updated offices and equipment. After 20 years now I know what a dentists office is supposed to look like and what dental work is needed. I wasted over 20 years on an old school sub par dentist. Getting everything taken care of the right way now


Staff is so helpful, and personable. Appointments are always on time. Helen is so caring, and efficient. She is concerned about me as she cleans my teeth. she also remembers what my kids and grandkids are doing. Always a pleasure to come to Dr. Helfner’s office.


January 2016

It is always a pleasure to go to your office. You and your entire staff are so very nice and accommodating, even when I have to switch my appointment because of my daughters’ upcoming tests. Your office is spotless and I love that the fish tank is back! When I am waiting for one of my children during their appointments, I thoroughly enjoy the magazine assortment and the beverage center is a huge plus! Thanks!


1st time in office. Loved it! The staff were very friendly and so helpful. Extremely knowledgeable as well! Never had such a great experience at a dentist office until i went here. I highly recommend this dentist office!


December 2015

Dr. Helfner and her staff are AMAZING!!! They are patient and sensitive to my needs (which are quite extensive!) They are friendly and helpful as well as efficient and competent!!!! This is the best office in any Medical Profession that I have ever been too. I am so satisfied with their service that my daughter is now a patient!!


My daughter was VERY nervous but thanks to Dr. Curro and Doreen she did great. They we’re both so gentle and patient with her and really made her feel comfortable.


November 2015

Hello. This is Sue, my mother came in for a crown recementing procedure this past Monday. She is a resident of Gurwin Jewish and had never met Dr. Helfner until yesterday. She could not stop raving about what a wonderfully friendly atmosphere your office provided to all patients. She had tremendous confidence in Dr. Helfner and felt that her professionalism and caring nature far surpassed her expectations. My mother was quite flattered as the staff could not believe that she is almost 92 years old ! What a lovely experience! Thank you all on her behalf and ours as well!


Dr, Helfner has been excellent. She is very thorough with explaining what’s happening and what she is going to be doing. Her staff is very attentive and organized . The office is very clean and has a nice feel to it. There are T.V.’s in the rooms to pass the time by. When I mentioned I only like mint flavor, she ensured it was noted in my chart for the future. She tries to make you very comfortable and will consistently ask how you are doing through procedures. She makes me feel very well cared for when I am in the chair. After a procedure I had, she contacted me after to ask how I was feeling. She was highly recommended to me and now I see why.


October 2015

“Extremely professional and caring. Although it is a business to be run and be profitable, the entire staff knows that we are there as patients, possibly needing some encouragement and TLC. Bravo to all of you.”


“Excellent care and excellent service. It is so hard to find a good dentist and staff. Everyone there from top to bottom makes you feel comfortable.


“I was extremely happy with my dental visit. My cleaning was great. Dr. Helfner was great. She told me a few things that my many dentists had never told me about my teeth/bones.”


September 2015

“Always welcomed and treated very well. I would recommend highly to everyone I know.”


“Loved my first appointment! Deep cleaning and full xrays this time and I liked how the staff gave you their full attention and time to do what they needed to do. Best part, the tvs!”


August 2015

“Great visit, i was able to fit in an appointment for cleaning and last minute filling, which was probably the easiest filling I’ve ever had!”


“Everyone is so friendly and helpful. Great service and accommodating schedules. For me the cleanings are painless. Everything I need to do is explained in cheerful tones. Highly recommend to anyone looking for a dentist.”


July 2015

“At the risk of sounding like a broken record (from one who remembers such things), the Helfner crew’s legend continues to grow. Another appointment, another flawless performance. Really, this is getting boring. In a good way, of course.”

– Silverstein

“I no longer have fear of the dentist. They listen, and understand how to respond to my needs.. The friendliest dentist office I’ve been to. I have no issue driving from Holbrook to Commack!”


June 2015

“I had a cleaning, two crowns and a filling done over the course of about a month. Every time I was at the office the staff was great. The doctor was friendly, funny and most importantly pain free! As most people not a fan of the dentist but if you have to have any work done on your teeth they are the ones to use.”


“Great as always! Ava said she wasn’t scared at all Dr. H made her feel so comfortable and she was completely fine the rest of the evening. Thank you Dr. Helfner for your call to check on her!”


May 2015

“I know it is hard to get excited about the dentist…I have had several root canals each done by a different dentist. This was, hands down, the best experience yet.”


“Dr. Helfner is the epitome of caring and professionalism.”


April 2015

“The staff truly put me at ease helping to calm my fears. I am hopeful that, with continued visits, my fears will be nonexistent. It was an amazing experience which was hard to believe could calmed given how petrified I was prior. THANK YOU SO MUCH!!!”


“What a wonderful group of people at this Dental office…They are all professional, friendly, courteous and immaculate…It is a very comfortable environment, you can’t ask for more than that…”


March 2015

“Although going to the dentist in general is not the most pleasant activity, my visit yesterday was excellent both with the care the dentist gave me and the actual procedure. I would highly recommend this practice to anyone.”


“I had a great experience. Everyone said hello, smiled, and acted personable and professional. My teeth cleaning was great! I felt like the hygienist was extremely thorough and did a wonderful job. Dr. Helfner was terrific too. I really enjoyed my visit and I’ll be back in 6 months.”


February 2015

“An absolute pleasure. I could not find an office as accommodating, nor could you experience a more pleasant staff. It clearly begins at the top and it is rare to find such a combination of expertise and courtesy.”


“I’m generally a nervous dental patient, and I was truly put at ease throughout my first appointment at Bonnie Helfner, DDS’s office. Everyone in the office was pleasant and I truly felt like my concerns were heard and I knew exactly what was going to happen along the way. What’s more, the dentist called me to follow up later that evening (my tooth was feeling much better already!), so I felt like she truly cared about me as a patient. I’m very happy that I called.”


January 2015

“My anxiety dental ridden 8 year old loves every single one in your office. It’s amazing the change from just a year ago, having to do IV sedation and holding down my daughter so they could place an IV. Yesterday, she actually let me leave the room while she talked cheer with your staff while Dr. Curro finished up her last tooth. She came out happy as can be with toys from the treasure chest and ready to pick out her Chapstick…I can’t say enough good things about the office. A true nightmare has turned into a pleasurable experience. I left out Sara as well who she loved cleaning her teeth on a previous visit.”


“Dr. Helfner is the best dentist!! And her staff is fabulous!! They run a punctual and professional office, they take the time to answer all your questions and will meet all your needs for cosmetic and family dentistry. They take most insurance plans and they are a friendly office…no stress at all!! Dr. Helfner’s warm personality eases your mind whether you are an adult or a child and her hygienists are terrific!! I wouldn’t go anywhere else!! Oh and she also resides in and gives back generously to the community!! This is the best dental office, where you get the best care and the best smiles!!”

December 2014

“Wonderful staff. Dr. Helfner is so easy to talk to and takes time to explain anything! Best experience at a dentist!”


“Wonderful Dentists, Friendly Staff, Immaculate Offices, Professionals Who Make You Feel Very Comfortable…Can’t Ask for More Than That…”


November 2014

“We had Dr. Helfner when my daughter was s toddler, she is now 23 and she is still our dentist.”


“I’d like to thank everyone at Dr. Bonnie Helfer office. I was in pain and they fit me in even so I was a new patient. They helped me when I was in a bind and new to Commack. They made me feel welcome and so comfortable. My own Dr. In Queens wasn’t even half as helpful. Everyone in the office was so amazingly nice. Dr. Curro is a doll. She was so patient, nice and explained everything clearly. These people are awesome! I was recommended by a friend and would in turn recommend them to everyone. Thanks Again!”

Maryann Varisco

October 2014

“Clean, cheery, state of the art dental office. Very friendly staff!! Going to the dentist is not always enjoyable, but my experience was!!”


“This is one the most professional dentist I have ever met!! The office is in pristine condition, the staff always greets me as family even know I only visit twice a year. Several years ago I recommended one of my clients to Dr. Helfners practice and the feedback was very positive as well! My favorite hygienist Helen, works so carefully and delicately on cleaning my teeth, I can almost say it is fun to see her for a cleaning… She always offers me head phones to listen to the television while she cleans away. I tip my hat to the entire staff at Bonnie Helfner’s office.”


September 2014

“Dear Dr. Helfner,

I had wanted to wait until the procedures were complete before answering. All of your employees and associates are top notch. My experience and the work that was done far exceeded my expectations and quite different than what I had been used to from other practices. Dr. Curro is probably the best dentist that I have had and I am completely satisfied with her professionalism. I intend to a patient in the future and thank you for your help.”

Stephen Freiberg

August 2014

“Dr. Curro is very thorough and very good at what she does. No wonder why they’re LI’s best. I’ve been to different dentists but their practice is the best by far. Wish I found them sooner. Everything is just organized and their staff is impeccable. From billing to appointments. I can’t stop raving about them.”


July 2014

“I was very impressed with the level of cleanliness at Dr. Helfner’s office. It was immaculate. Every member of the staff is professional and courteous.

I am beyond happy with my experience at Dr. Helfner’s office.”

She will make even the most apprehensive patient comfortable.”


“Excellent experience! Everyone is always so nice, and I didn’t feel any drilling while having a cavity replaced. The atmosphere makes you feel like your amongst friends.”


May 2014

“The best dental experience I have ever had! Helen was so patient with me and Dr. Churro was very thorough. I wish I had known about them 10 years ago and I could have avoided all the work I know have to have done. I feel very comfortable with them. Thanks.”


“The decor, the front desk staff, Sara, and Dr. Helfner all made me feel relaxed. Dental exams and treatment are very stressful for me but this office has made me feel better about keeping up with regular visits.”


April 2014

“Dr. Helfner’s office has very courteous and professional staff. It is always a pleasure to visit her office. Dr. Helfner is very knowledgeable and most of all caring. She is absolutely wonderful with the kids! My kids look forward to seeing her!”


December 2013

“Dr. Helfner and her staff are the best I have ever been treated by! Not only does Dr. Helfner have all state-of-the-art equipment, she and her staff are completely compassionate, patient and gentle. Dr. Helfner is also very considerate of my time and sees me at my appointment time. However, she has also made herself immediately available when I broke a tooth. I highly recommend Dr. Helfner for all general dentistry needs!”


July 2005

This office is amazing. From the front desk to the back…everyone here is friendly, compassionate, and above all…extremely competent. A visit to this office is not like going to your traditional dentist. They treat their patients like they’re family. Who looks forward to seeing their dentist? The patients here do, and that speaks volumes about this practice. You have to experience it to believe it!


“I have never been to an office that delivers such fantastic customer service. From the minute I called the office to schedule an appointment I was handled with the upmost respect. I work a lot and my availability is limited. The woman on the phone patiently worked with me until we came up with a time that worked with my schedule. I have already brought my husband and my two children into the office as new patients. I am beyond thrilled with the level of professionalism and I am proud to be a patient of a practice with such a positive reputation in the community. Thanks to Helfner’s Heroes!!!”
