We are relatively new patient at Seidner Dentistry having had a long and very positive relationship with our Periodontist for many years in Greenwich Ct..
We moved to the area and had to find all new Drs. and Dentists. The 1st practice was an absolute disaster for many reasons.
Luckily since following several recommendations, we gave Seidner Dentistry a try with a little trepidation.
However 2 years in their care my husband and I have had nothing but positive experiences.The office is very pleasant and well equipped, The Staff from the moment of check in is always friendly, polite and welcoming.
The waiting room is very comfortable. Our appointments have always been honored regarding the scheduled time.
The Hygienists are welcoming and do an excellent job communicating what they are doing and seeing that we are comfortable. And up until my last cleaning which we get 3 x’s a year, our choice because we like to take care of what we have been given.
This time 2 small cavities and a large crack in an older filling required a Crown. Not what we want to hear but I decided needed to be done.
The Dentist offered to begin the work to put a temporary Crown on to prevent saving me time and energy waiting to begin the process.
I left that appt.with my Temporary Crown in and my appointment made for when my permanent Crown was ready to go.
The attention to detail gets 5 Stars, the level of care during the appointment was 100%putting me at ease and ensuring my comfort every step of the way.
I wholeheartedly recommend Sneider Dentistry and highly recommend them for your Dental health and care.

I’ve been a patient with Seidner dentistry for over 20 years and they have always been top notch. Their entire staff is always friendly and professional, and the work they do is exceptional. While they are always efficient during a visit, you never feel rushed and know that they will take the time needed to be thorough and address any questions or concerns you may have.

I don't usually leave reviews but the outstanding professionalism, care, and detail each and EVERY staff member consistently gives you warranted me taking the time to do so. There's a reason I travel 40 miles to go here; it's the straightforward, honest, caring, capable and efficient dental office that never disappoints. Highly, highly recommend Seidner Dentistry.

I’ve been coming here since I was a child, and Dr. Kim has been my dentist since my very first visit. Even now at 27, I still struggle with dental anxiety, but he has always made me feel comfortable and reassured every step of the way. He truly listens to my concerns, he has always gone above and beyond to make me feel calm, comfortable, and taken care of.
After all of the procedures I’ve had done over the years, I’ve never once left in pain, which says everything. I’ve seen other doctors in the office as well, and every single one has been wonderful, but I will always come back to Dr. Kim. I couldn’t recommend him more!

I’ve been going to Seidner Dentistry for so many years now, and the experience is always so great. It starts off super pleasant with a very warm welcome from the check in receptionist. The receptionist always has a great way about herself and makes you feel welcome. The waiting area is open and clean with comfortable seating, so overall I wouldn’t mind hanging out in the waiting area, but the wait times are always minimal as the Seidner Dentistry team really care about your time. My oral hygienist Ava always calls me in right away and she’s absolutely the best. Ava is super sweet and most importantly super talented, you can tell after the experience how much she really cares about her craft. In the past I was usually pretty apprehensive at dentist offices, but Ava makes you feel super at ease to the point where I believe I may have dosed off briefly. The examination is concluded with a goodie bag full of oral hygiene products and a checkup by an on staff dentist which is also super friendly, knowledgeable, and thorough. I do not recall the name of the dentist who saw me today, but she was very friendly and funny actually. The experience is concluded with the checkout receptionists which is also super friendly and sends you off feeling appreciated. Overall, as you can tell, I highly recommend Seidner Dentistry!
