My experience was at first positive and then very negative. He's very gentle, and his office is…read morewell-run, efficient, and gorgeously decorated. I often saw his wife, the receptionist, giving gifts to the child patients.
However, like another person mentioned, there's a side to Dr. Tsai and his wife, Susan, that comes out whenever there is a deviation from this tightly controlled environment. In my case, the osteopath that Dr. Tsai was co-treating with was out of town and unable to help me when a molar got loose due to the dental treatment that the other osteopath was supervising. Dr. Tsai felt how loose the tooth was but refused to cover for the absent osteopath. He said I would be safe if it only lasted "up to two weeks." At three weeks, the tooth was on the brink of falling out, but the appliance was still in while we waited for the return of the other osteopath. Again, he had the option of helping me fix the appliance (at the dentist's) that week. He not only refused but this told me that it was okay to have this tooth getting looser for "up to three weeks." When I asked him to clarify, because last week, at two weeks, he had said "two weeks," he argued with me, insisting that three weeks was okay. Then he asked Susan when the other osteopath would be coming back to town. "Next week," she said, and he ran his hand through his hair in irritation and then walked away.
That molar was so damaged it is now a source of endless problems and has made any further orthopedic or orthodontic interventions next to impossible. It literally would have taken him five minutes to help save that tooth, and by extension, my jaw.
To watch him walk away from something so simple, easy, and ethical profoundly shocked me. I guess he was afraid of stepping on the other doctor's toes, but this was an emergency.
To be gaslit, told that I had misunderstood the first (accurate prognosis), simply because he refused to help was highly unethical traumatic.
To make matters worse, Susan became very rude to me after this.
