Dr. Trellis is a very caring person. He always looks at my recent visits to my PCP and cardiologist reports and talks to me about them. everything is in the computer and he always looks at everything. I have an auto immune liver condition and he makes sure that I get my blood work done and take my medicine.

This was my first visit with Dr. Trellis. While he seemed knowledgeable, I didn't feel he took the time to listen fully to my concerns and understand the history of the issue at hand. It was difficult to answer his questions adequately as it seemed he was trying to hurry through the appointment.
