“This dental office is studded with SUPERSTARS! From the admin staff members Sue and Pattie to the incredibly gentle, friendly and expert dental hygienist Andrew to the wonderful doctor herself, I received a top notch experience for my initial appointment and felt comfortable and reassured every step of the way. I have always been anxious towards any dental care yet this visit was the most pleasant I have ever had in my life. Much appreciated!”

Katy K.

Polk Gulch, San Francisco, CA

I came in recently as a first-time patient for Zoom teeth whitening which I had purchased at a charity auction. The office staff was friendly and helpful, and Dr. Potesta-Knoll was very careful and thorough with the whitening process. It may not be something one would normally say about a dental appointment, but it was a pleasure. Thanks Dr. Potesta-Knoll and Sue for the great service and for contributing to our school fundraiser!

Dr Potesta and Patty and Sue are very nice people. And good at their jobs! I have always had fear of going to the dentist but they make me feel very comfortable during the procedures.

Susie A.

Dr. Podesta is very attentive and thorough. Her skills are precise with no pain. I was amazed considering all the surgery I required but with Dr. Podesta's skill along with her staff and the amazing view of the bay and Golden Gate Bridge I was so relaxed leaving with complete trust and respect for Dr. Podesta.
