Our Reviews

I suffered a fractured tooth while traveling to the US and had to get through an acute process of a root canal procedure, followed by a crown build. The staff was very professional and extremely helpful in getting everything set up in just a few days. The procedures were performed with excellence and without any pain or discomfort for me. My crown fits perfectly. I left the office with a smile on my face!

Dr. John took great care in understanding my anxiety, and it was the first time I’ve had a filling done where I’ve not felt any sensitivity during or after the procedure. Go see him.
Morgan M.
My wife and I have been going to Dr. John in Soho for years. Best dentist either of us has ever had by far. The office is super nice and clean, and they are always on time. The entire team is top-notch. Highly recommend switching dentists to Dr. John!
David K.
Highly recommend this place. Everyone here is very friendly and professional. I previously had veneers that were very bulky and uncomfortable. I was worried I didn’t have any solution until I came here. I can’t thank Dr. Koutsoyiannis enough for giving me my smile and my life back!
Zachary K.

Dr. John Koutsoyiannis is the absolute best dentist! I’ve never had such a thorough examination before. He and his team listened to all my concerns and questions and made me feel very comfortable and eager to go see a dentist. He is very professional and kind. The whole process was seamless and the work done was painless and looks amazing!
Toni B.
This was more like a trip to the spa than the dentist. The facilities are calming and beautiful and you get to pick a movie to watch while having your teeth cleaned. The staff is friendly, knowledgeable, and detailed in their examination. Highly recommend!
Kayla W.
Such a lovely place to go to. My teeth look amazing after Invisalign treatment and I always feel so welcomed and taken care of. The place is super clean and the overall best dentist experience I have ever had.
Sofie B.
His care and experience, coupled with good tips on taking care of teeth, have allowed me to keep my teeth free of problems. His office also takes preventative care very seriously. At a routine cleaning, he caught a potentially life-threatening issue before it had a chance to cause any problems. Thank you Dr. John for the unparalleled care and treatment!
