Had such a fear of the dentist until meeting Dr. Sullivan. Thank you to Dr Sullivan for providing such amazing care. The follow up phone calls after having work done is just amazing. Something that completely caught me off guard in a good way! Thank you for such amazing care you and your team provide!

Dr Sullivan is amazing! He brought my smile back. I had several broken teeth and he has worked with me through many appointments to bring my smile back. Thank you Dr. Sullivan

Dr. Sullivan is the best and I've been going to him for many years now! He's patient and caring and makes you feel comfortable. Going to the dentist doesn't have to be scary when you go to him!

Dr. Sullivan is an angel. His knowledge, experiences, kindness, patience and wisdom is top notch. He really listens and does such a great job and more importantly, a painless experience every time i have had a procedure. The office staff are angels and I highly recommend. Lastly, Dr. Sullivan calls you the evening after your procedure to see how you are doing! Who still follows this practice in 2021. We are lucky if we even get an appointment or physically see the doctor now days. 5 STARS

This review is for the services the Doctor has performed as well as being a former employee of the office. He is one provider that will give you honest care, build a relationship with his patients & has so much education over the years to identify dental concerns that many other Doctors don't have (one of many being TMJ). Dr. Sullivan has done extensive work on my immediate family fixing years of botched dental work from previous dentists.

He was able to locate the issues as to why there were failing bridges on one individual & located a file used in a root canal on another family member that was LEFT in the canal from a previous dentist that caused him pain for years. They both travel about 40 miles from their home & will make the commute & have not returned to their previous dentists.

I worked for the doctor for some time & have to acknowledge how well he treats his employees. It is far & few to find a boss similar to him. It made for a great working environment, it allowed the staff to built relationships with our patients on a level of knowing each face that came through the door & their families which was very important in that office in which I miss many of our patients!

Even after leaving (pregnancy not another job) running into some obstacles the staff & doctor were still there in the time of need. It's such a rarity especially with covid affecting businesses and households to come across individuals like so. If your looking to build a relationship with a office for your dental needs & receive great service; this is definitely your go to office.

I have been going to Dr. Sullivan for my whole life even since we have moved further away from the office. The reason is I always experience exceptional care from everyone in the office, and of course excellent dental care. My husband goes here as well now and has had such a great experience than with his former dentists. I can't recommend them enough.

I've been coming to Dr. Sullivan for years. There are many good dentists but very few that could compare to his expertise. There isn't a specialist around that will be your advocate and work harder for you to give you the best treatment and smile than Dr. Sullivan. I've attached the sheer number of continued learning and accreditation's that he has amassed over the recent years.

Dr. Sullivan is an extremely competent Dentist. I've been his patient for going on ten years. I live about 45 miles from his office but won't see another dentist in my own town. He will always make time in his busy schedule if I have an emergency. He's simply the nicest, most qualified, dentist I've ever seen in my lifetime and I'm 73 years old! I highly recommend Dr. John.

Dr. Sullivan is the most amazing dentist/doctor/medical professional I have ever met! He is so nurturing in the way he speaks and explains things, really puts you at ease. I saw him thinking I needed a filling (was in pain for several days) but ended up needing a wisdom tooth removed. It was my first time having to go through this and having heard all the horror stories from others I was starting to panic. Dr. Sullivan put my mind at ease, explained everything in detail, and was just so encouraging!

Most importantly, he performed the extraction so swiftly and with such care, I didn't get a chance to worry before he was done! He is incredible and so good at what he does, a true professional that I will forever recommend to everyone! Feel so lucky to have discovered him thanks to others' lovely reviews!

Dr John Sullivan is excellent with kids and one of the best dentists that I have been too. He is patient and always explains what is going on. Took our 3.5 year old and it went very well. Cavity all fixed. Thanks doc!

I was looking for a second opinion on some teeth that were bothering me and I needed to see a dentist ASAP. Fortunately I was able to make an appointment with Dr. Sullivan right away and just from speaking to them on the phone I could already tell that I was going to be in good hands. Georgia at the front desk was very helpful and welcoming as soon as I arrived and the paperwork you fill out as a first time patient is harmless. Dr. Sullivan was able to give me a second opinion in a matter of minutes and after a few x-rays, we were able to come to a satisfying conclusion. Dr. Sullivan is very knowledgeable and its obviously that he loves what he does and genuinely cares for each of his patients.

My mother, father, brother AND sister all see Dr. Sullivan and have been for the past couple years. I can only speak on behalf of my minor encounter with Dr. Sullivan but each of my siblings always have good things to say after they get their cleanings. Thanks again to everyone at Dr. Sullivan's office, my teeth and I really appreciate it!

Extremely trustworthy dentist & a perfectionist. Everyone makes you feel comfortable at the office & quite informative. I had a night guard made (grinding my teeth & broke off a crown :/.) He had me in the chair for a while because he wanted it to fit PERFECTLY. Very friendly doctor & honest work. He will not trying to rip you off with unnecessary work. Would recommend Dr. Sullivan's office! Very friendly & accommodating office.

My coworkers suggested I see Dr. Sullivan since I was in the market for a new dentist. I had a deep cleaning and all 4 wisdom teeth taken out and would say it's the most laid back dentist office I've ever been to. He was professional but talks to you like a person- not condescending like others tend to. The staff in the office were happy to greet and help with any other questions I had. Dr. Sullivan himself called me the next day himself to see how I was feeling despite it being the weekend. I definitely recommend his office for getting any work done!

My regular dentist referred me to Dr. Sullivan to help me with my TMJ/TMD issues. I live about 40 miles away from Dr. Sullivan and was skeptical that it would be worth driving so far to see a dentist. I'm so glad that I did drive all that way because he has really helped relieve a lot of my pain with the mouth guard that he made for me. He's very nice and has a good "dental chair" manner. I highly recommend Dr. Sullivan even if you live far away like I do.

I'm a new patient and I'm so glad that I found Dr. Sullivan. I had some problems with my old Dentist and he is completely different. He and his staff do a great job and truly seem to have the patient's best interest at heart. I am so happy with their service I even sent my son to him also

Dr. Sullivan has been my dentist for over 12 years and I have to say that he is the very best! He is kind, gentle, and extremely knowledgable - always bringing the latest technology into his office. He and his staff are all very warm and friendly people. I go to his office for cleanings twice a year and am always impressed by what a great job they do!

Although I live in the city and have a choice of hundreds of dentists that I can go to, it's worth the drive for me to see Dr. Sullivan. I highly recommend Dr. Sullivan and his staff!
