What other people are saying

Tim J.

I highly recommend this office, from the receptionist to the tech to Dr. Greenberg. I had my wisdom teeth pulled out, and the expected cost was told upfront—nothing additional or surprise costs. The follow-up was easy, and I feel so much better.

Joyce B.

Dr. Andrew Greenberg is truly an exceptional doctor and a remarkable human being. When I was in agonizing pain and no one else would see me even though they could clearly hear the distress in my voice.  Dr. Greenberg and his amazing staff stepped in without hesitation. He not only saw me promptly, but did so with a level of compassion, professionalism, and empathy that is incredibly rare.

Claudette B.

Dr. Greenberg and his assistant went above and beyond to make me feel calm and cared for. I’m so grateful I chose this practice. Next step—implant! I highly recommend them.
