Although this was my first visit to this specialist after a hospitalization, he was very knowledgeable about my condition and gave me great treatment options.

Care provider listened and discussed a new treatment for me.

This Doctor was a refreshing change to the inept providers I have had in the past. I thought he was very knowledgeable on the matter and straight forward with his responses. I wish he were closer to home and in general practice.

was seen next day after contact for appointment dr was great

Dr. Ayasso interrupted me several times, made an unhelpfully judgmental comment about marijuana use and referred to his female receptionists as "The girls", which I found patronizing.

May 15, 2019

Felt he took time to hear and make a plan to address my concerns and didn't dismiss me. He had gotten interrupted by calls from the hospital twice during the visit, but I felt he was genuine when he apologized instead of making me feel secondary. That is a positive for Dr Ayasso as many doctors I've had in the past would not have acknowledged the patient as their first priority and simply left to do what they needed to do. I think (hope) that demonstrated that he will be caring and concerned about his patients getting the answers they need.
