I went in for results of my colonoscopy, but I was also able talk about other problems I had with my liver.

I am new to this disease I have been diagnosed with and have a lot of questions. Dr. Tsai was so tone deaf and insensitive to my needs as a patient he made me cry. I'm 61 years old, have had cancer before and been through it all and I can honestly say this is the first time anything like that has ever happened to me. Then in his notes he said all of my questions were answered. That is not true and I don't know how he could think that. Like I said, tone deaf. I don't know if I can bring myself to go back because he made feel so uncomfortable and has negatively affected my mental state for the three days following the appointment. That is not going to help me get well.

On one hand Dr. Tsai is fabulous, however if I recommend him to others and his list of patients grows, then that will further impact my ability to get an early appointment. I do always tell people that he's the best. I simply don't recommend that they switch to him and further complicate my life.

I been seeing this dr for a long time going back 30 years but it seemed like he wanted to just hurry and get me out. It was a scary time cause the prognosis wasn't in the best I am very worried.

Dr. Tsai was very apologetic for the delay. He explained they had a few urgent cases that set them back. I suggested that he let the staff tell patients and give them a choice. He was very receptive to the idea and would let the front know.
