In all the years that I have had going to doctors, I have never gone to a doctor as wonderful as he is. This man had patience, explained things to me that I never even knew what was wrong with me. He is absolutely a fantastic doctor and words can't even say how marvelous he was, the way he talked to me and answered things and I am so happy that I got to see him. Thank you, thank you, thank you.

This doctor, Sides, was extremely thorough and spoke on a patient level, not at a doctor level to the patient and very, very informative. Taught us so much about his condition and we were extremely grateful.
