PATIENT REVIEWS

Check out what some of our happy patients are saying about us:

Melissa K. from Ronkonkoma, NY (Source: Yelp)

★★★★★

Just took my son for a free evaluation. Our dentist had referred us to this office. He was nervous but the staff and doctor eased his anxiety. Its a large fun office. All they did was examine him and told us he was not ready yet.  It was nice to see they were not in a rush to do anything and informed us they will start at the right time.  We will be back in 6 months for another evaluation.  Just hope he starts soon so he can get them off before high school.

Today I visited Island Orthodontics with my kids and was greeted by the warmest staff members and Dr. Zach was a pleasure to speak with. The place is very clean and well organized and disinfected! No one had an attitude and they were very personable and professional. I would definitely recommend them and my kids cannot wait to go back! Take care and I wish you the same success.

★★★★★

Island Orthodontics has taken very good care of both of my children’s teeth and were always very professional and easy to make appointments with. I would recommend them to anyone looking for a great orthodontic practice.

Christina M. from Nesconset, NY (Source: Yelp)

★★★★★

I had quite the opposite experience with my kids here from the previous reviews. They are always packed and busy in the afternoons when we are there and I am surprised the reviews are so negative. If it was that bad I feel I would see less people but it is a VERY busy office. My kids enjoy it because it is so kid friendly and I never have a problem making an emergency appointment. They always accommodate! Love the girls up front and the doctors and assistants will answer all my questions. I never waited more than 5-10 minutes.

★★★★★

I was told by 3 other orthodontists that my son needed all kinds of things starting as young as 2 years old. This is the only office that didn’t make me feel like they wanted to ring up a tab on my insurance. They were honest, easy going, patient , professional and never made me feel I was being taken for a ride. Hats off to this breath of fresh air I would recommend anyone I know to this awesome office!

Gemma M. from Nesconset, NY (Source: Yelp)

★★★★★

I’ve been going to this office since I was a child. First to fix my bite with an expander and then to full braces as an adult. I have never had any issues with this office. The girls up front are awesome and are very helpful when it comes to insurance issues and the doctors are always there to answer any questions. It is a very very busy office with lots of patients, especially after school. I think its so busy because they are that good. They accommodated me that day when I had an emergency unlike other offices that ask you to wait a day or 2. I feel if you have questions, you need to ask and they will be glad to help you.

Marybeth C. from Ronkonkoma, NY (Source: Yelp)

★★★★★

They are wonderful! All 3 of my kids have gone there. Everyone is super friendly. Office is always clean. Our wait times are always short. They even give us same day appointments if there is a problem with the braces.They do fun outings every year. We love going pumpkin picking, mini golf and to movie mania.  We wouldn’t use anyone else!

★★★★★

ISLAND ORTHODONTICS is by far the best place for children and families looking for that beautiful smile!The staff is always welcoming and professional. Post Covid they have re-opened their doors following all CDC guidelines while still making it feel like a warm place to be! I can’t wait to see my children’s new smiles! Thank you ISLAND ORTHODONTICS!

★★★★★

It was quick and easy to get in to see the orthodontist, especially in light of the COVID 19 measures put into place. Dr. Zach was honest and treated my daughter as a patient instead of trying to earn more money – he told us to wait six months as my daughter is a little young for braces.

Michael C. from Ronkonkoma, NY (Source: Yelp)

★★★★★

This is definitely the nicest orthodontic office I have ever been to – like a playground for kids but also brand new equipment and very impressive to adults. Their new office manager always explains everything to me and is very informative. I don’t have any trouble making appointments and the whole staff was very friendly. Definitely by far the nicest office I’ve ever been to with the best, most professional and friendly staff. I can never go anywhere else now and I would recommend it to anyone with kids

Kay D. from Bay Shore, NY (Source: Yelp)

★★★★★

Island Orthodontics is the best Orthodontics on the South Shore! I’m very pleased with the work that have been done with my child’s results during and after removing the braces were removed. The office is very child, and teen friendly. The staff is beyond excellent! Very professional, caring, and timely. This is top notch when it comes to a patient and doctor relationship. I will forever be grateful to Island Orthodontics! Thank you so much for all the care, and helpful tips after braces are removed.

★★★★★

Best ortho office hands down, the desk staff are so kind and caring towards me and my daughter Paris and the doctors are wonderful and know what there doing. Even with the covid 19 going around they do social distancing properly and use a text system while you are waiting. You dont have to wait long there very good at time management and get you in almost as soon as you come. Wonderful orthodontic office I highly reccommend them.

★★★★★

They were very professional and honest! Dr. Zac told us to come back in 6 months for another eval when we were told by another orthodontist that my son needed a palate expander, spacers and braces just for phase 1. So glad I got the second opinion!!!

★★★★★

I would recommend Island Orthodontics because of their welcoming environment. Usually a child is scared to get their braces on but they ensure it is nothing to worry about. Island Orthodontics is a great place.

Cindy Shek-Silverstein (Source: Facebook)

★★★★★

The office staff are very accommodating. They have always found a way to squeeze in all three of my kids so I don’t have to make another trip. The clinical assistants are friendly and make the children feel comfortable. They explain what the what they are doing so they know what to expect. The doctor’s are all friendly and explains the process in layman’s terms.

★★★★★

So happy with the results of my daughters smile. It was a long journey but so worth it. The staff is the best, they are friendly and informative. The office space is comfortable. Plenty of parking always in the parking lot. I highly recommend Island Orthodontics!

i have never once had a bad experience here during my time. everyone cares a lot about their work and it shows. Even reception always greeted me with a smile and made me feel comfortable as soon as i walked in. if i could leave a higher rating i would. 11/10 for orthodontic work and personal attitudes.

★★★★★

Both of my sons have had braces here combined over the course of 7 years. We couldn’t be happier with the results and the staff. They are always smiling and very patient with my kids explaining everything that was being done. I can’t say enough nice things about the Deer Park office!!

★★★★★

This is my second time around with Island Orthodontist. I (like so many others) lost my retainers and never thought of replacing them, so I let years go by and of course my teeth spaced out again. So at the age of 23 (now 24) I had to get my top braces back on to close my middle gap. 10 months later I finally got them off! The staff was nice every time I walked in the office. I’m happy with my teeth and I’ll remember to keep my retainers in lol.

Aaron M. from Nesconset, NY (Source: Yelp)

★★★★★

i’ve only been here with my kids a few times since my wife goes to most of the appointments. I was surprised how many people there were and how big the office was. They allowed me to sit with the kids during their appointment and their appointments were less than 15 minutes. We were in and out without any issues. My kids and their friends go here and they are happy so I am happy. It’s a great office that gets the job done and they have a great smile too!!!

★★★★★

We went to Island Orthodontics last night to discuss the treatment plan for my almost 11 year old son. The office was clean and fun for the kids with touch screen tablets to play games on. Checking in was easy too and didn’t wait long to be seen. The doctor was nice and professional and went over the treatment plan with a video so my son and I can understand the process. Very friendly staff and we’re very happy with them.

★★★★★

Everyone from the receptionist’s to the doctors’ and to the doctors’ assistant’s are nice, We are always greeted with a smile, My daughter of course was nervous and by the time we left from the consultation she was so ready to get started to have her teeth straightened. I highly recommend this group!!⭐️⭐️⭐️⭐️⭐️

★★★★★

Extremely professional, caring and dedicated team! The care they provided for our son was exceptional. I highly recommend Island Orthodontists for families. They explained everything to our 8 year old and made sure he was comfortable the entire process. He absolutely loves going to the Orthodontist now! The team treats each patient like family and takes their time to provide top quality care. Now our 7 year old can’t wait to get braces!

Island Orthodontics is an excellent office. The staff are very kind friendly and efficient. Office is well designed, clean and they are following all CDC COVID guidelines. Everyone wears mask properly, hand sanitizer, even wipes down pens and credit cards at front desk. Seating is social distanced, if you are in waiting room for short moment. Also no waits as you are called in one by one, from waiting in car to keep social distance measures. I definitely recommend Island Orthodontics for all orthodontic needs whether pediatrics to adults.

Maureen W. from Holtsville, NY (Source: Yelp)

★★★★★

My 2 sons are both being treated at Island Orthodontics.  The office staff is very helpful as there were a few emergency appointments I had to make because of broken braces and I was able to get in right away.  The doctors always take the time to discuss the treatment plans of my children.  I am very satisfied overall with the care provided at Island Orthodontics and would recommend them!

Helen Y. from Nesconset, NY (Source: Yelp)

★★★★★

Both of my children have been coming here since they were 8 years old.  I love that I can come in when my kids have an issue or poking wire the day of and without waiting.  I still have 1 child in braces but I am happy with the results of my first child. I can’t wait to see my baby getting them off.  It’s definitely a place I would go if I had to get braces again…

Nelle O. from Ronkonkoma, NY (Source: Yelp)

★★★★★

I have 3 children and all of them have gone to Island Orthodontics. A neighbor recommended them and I have yet to be disappointed. Walking in is a pleasure. All the receptionists are friendly and helpful. The kids sign themselves in on the computer ( they love that ) and I’ve never waited more than 6 minutes! (and 6 minutes is pushing it! – it’s usually on a few minutes!) They have a great payment plan if insurance doesn’t cover orthodontics .. reasonable and fair! The techs are also great and my kids always come out with a smile…! My oldest daughter didn’t wear her retainer and the office manager worked with me and gave s a discount on getting braces for the second time. Great person who went the extra mile.. They also do great things with the kids throughout the year. In the winter there is the movie day sponsored and paid for by Island Orthodontics! In the fall they have the pumpkin picking and hay ride… they’ve also had mini golf and other events throughout the years that my children have been patients. If all doctors offices were like this life would be perfect! Island Orthodontics needs to give lessons to other practices!

★★★★★

The Island orthodontics on portion road in Ronkonkama is a fantastic office to go to. Not only is the service their excellent but so is the staff. The front end worker Victoria is an excellent help. Anytime I visit the orthodontist she is always willing to answer any question I have and assist in any way possible that she can. I am happy that someone like Victoria works there.

This office is one of a kind! Their staff are the most caring genuine professionals I have ever dealt with! They are a pleasure to speak to with concerns to my girls’ treatments and just everyday life! A very clean office and we never wait long! I would recommend anyone looking for an orthodontist call Island Orthodontist 🙂

I have been going to Island Orthodontics for my Invisalign aligners for about 2 years now. They helped give me a perfect smile for my wedding back in December 🙂 I am very happy with their service. Everyone who works there is friendly and the doctors are always happy to talk to me about how my teeth are moving and answer any questions I have. I recently had a visit to the office in which they added multiple safety procedures because of COVID. They texted me to come inside, took my temperature and provided hand sanitizer. Everything was very clean and I could tell they took the safety of their patients and their employees seriously. I highly recommend!

Love this place. I’ve been bringing my children here for well over 2 years and I’ve never had anything less than a great experience. The staff is very kind, patient and efficient. I always recommend them to any family and friends looking for an orthodontist.

Dr. Zaks and his team of doctors and assistants are exceptional! They make the process of Orthodontics easy and are all extremely professional. I highly recommend them for anyone interested in or needing braces!!

My first time ever at Island Orthodontics was VERY GOOD from when I walked in the door Until I left the ladies are all happy and very helpful smooth sign in and the atmosphere is perfect. I love the decor. The wait from signing in and actually being seen was quick, when we were brought into to room for my son to be looked at the wait for the Dr was also quick. He was very informative and pleasant to speak with. I would highly recommend them for anyone that needs a straight smile

Our daughter goes to Island Orthodontics & loves them! The doctors are very professional & kid friendly. From the tablets with games for the kids in the waiting room, to the televisions in the oversized exam room, everything is top notch. They even give my youngest a balloon every time she tags along. I highly recommend them. Fantastic service every time!
