I was a patient of Dr. Senn’s for almost a decade and very much appreciated all of the excellent dental work that he did for me over the years. His staff were incredibly helpful and friendly and I always looked forward to my appointments for teeth cleaning and repairs. This all ended with the reorganization of his office in 2019 and the arrival of the woman billed as the office manager, Lisa. I have never encountered such a rude and disrespectful person who was supposedly occupying a position that was supposed to be helpful and accommodating to patients. After she appeared to deliberately botch up some insurance payment information around some expensive dental work that Dr. Senn did for me, and she continuously gave me misinformation around the claim, I realized that I was dealing with someone who more that likely was suffering from a serious behavioral problem. I decided with some sadness to find another dentist. Happily I did and one that is closer to home in Petaluma where I live. However, the dealings with Lisa at Dr. Senn’s office in Sebastopol were not quite over with yet! My new dentist’s office requested my last set of x-rays from Dr. Senn’s office. This was not an unusual request and is common practice. The next thing I know I receive a call from Lisa that I must sign a release form for the x-rays which was fine by me, but she also informed me that I would have to pay a fee! My husband is a doctor and according to him and to my new dental office, demanding a fee for the release of my x-rays was not only unethical but also illegal. I called Lisa back and told her that I refused to pay any fees for the release of my x-rays and further that I would lodge a complaint with the Dental Regulatory Board and the Better Business Bureau. Shortly thereafter my new dental office received a very incomplete set of old outdated x-rays. So much for cooperation and working on behalf of a patient’s best interests. I have no idea how a seriously disturbed person like Lisa can be allowed to wield so much negative influence in a dental practice that once prided itself on genuine care and compassion in dealing with its patients. That Lisa has been allowed to continue with her toxic behaviors without Dr. Senn or Dr. Mann intervening is incomprehensible to me. That this woman hasn’t driven off most of Dr. Senn’s patients is miraculous. I have no idea what happened at Dr. Senn’s practice to allow such a person as Lisa to wield such control over every aspect of the office, but I am deeply sorry that it came to this. Meanwhile, I am very happy with my new dentist and aside from being a real state of the art practice, my new dentist is incredibly knowledgeable, highly skilled, and genuinely compassionate and thoughtful, and the office staff are all genuinely friendly, highly competent and free of any obvious psychological issues.
