I have had terrible experiences with dentists through out my life and can be very particular about my dental services especially when it comes to discomfort. Igor Kostanyan is the best dentist I’ve ever had. Personable, direct, listens, and has a great since of humor. I’ve had MAJOR work done by him this hear and for the first time in my life I’m always happy to go back to see my dentist. TAYLOR LAMBERT, 5 Stars Review - Google

I come to Dr. Sarji because he knows I need a lot of Novocain and time before any work starts.

The ‘Gentle’ in the name is very accurate.

I have been using the services of Advanced Gentle Dentistry for several years. The office is modern, clean and everyone is professional. They do their best to be flexible with the patients schedule with regard to appointment times. The waiting room is pleasant although I am happy to say that you do not spend much time in the waiting room. I highly recommend. 5 Stars Review-Google
