Laura at the front desk keeps everything rolling smoothly. Dr. Lester answered all my questions and was very thorough and approachable. I feel very well taken care of from this dental office.

Dr. Lester and staff provide excellent care. I have a lifetime of dental work due to trauma early in life. When I suffered a broken tooth, she made time to address it even though I was not a patient of hers at that time. Since then I have had multiple visits attending to multiple cracked teeth due to 50+ year-old fillings as well as a dental implant. She and her staff have been kind and gentle.

When I moved to Petaluma last April I didn't have a dentist. For many years I had dental problems so finding a new dentist was really important. Finding Dr. Lester, and having her treat me has made me feel confident that I will not have dental problems since she is a knowledgeable, caring person.

Do NOT go see Dr. Van Tassell. If I could give zero stars I would. This is the first negative review I've ever written as I really do like to give people grace and not blast them on yelp but this has to be said. My 6 year old son was seen at his regular dentist on July 21st and needed a tooth extracted. The dentist said it was urgent so she got me in the next day. They did the nitrous oxide but my son still went into a panic and was screaming so we could not get it done. We were referred to PDI (Pediatric Dental Institute) so that they could do the procedure under general anesthesia. But because we have Kaiser medi-cal we had to be seen by a dentist/oral surgeon that was in the Kaiser network. Enter in Dr. Van Tassel. 3 weeks later and after 3 canceled appointments and my son being in severe pain I called into Kaiser to get authorization to go out of network. I talked to a very nice and understanding Kaiser doctor who understood my concerns and spent hours trying to get authorization for me. Finally, he said I would be able to go to PDI and Kaiser would release my son so we could get the dental surgery done. PDI said if they received the formal authorization quickly we would possibly be able to do dental surgery the very next day. But then I get a call back from the Kaiser doctor who said that Dr. Van Tassel needs to release my son and she would not do it because she felt like she could get it done in a timely manner and would be back in the office next week so we could do an ASSESSMENT...not even the surgery. She said that it was not an urgent matter. Kaiser only gives two dates a month to do oral surgery so we would then have to wait for the opening. The Kaiser doctor explained to Dr. Van Tassel that my son was in a lot of pain and she replied that we could go back to our normal dentist to get pain management. Are you serious?!? How cold and heartless can you be to not release a 6 year who is in PAIN so that you can get paid to do the procedure after THREE weeks and THREE canceled appointments?!? This is beyond unacceptable. I will be figuring it out and paying OUT OF POCKET to get the surgery done at PDI because there is no way I would trust my son to be seen by this woman.
