Steven Liu, M.D.
I think he's a very efficient to the point doctor but I wish she was more on time each time I wait more than 30 minutes
Kambiz Behzadi, M.D.
Everyone was extremely professional & very pleasant. I've seldom had an office visit where I felt more relaxed or received more actual attention by all during my visit. Very impressed with my 1st visit.
Kambiz Behzadi, M.D.
I’ve been seeing Dr. Behzadi for years and I can’t recommend him enough. He is very knowledgeable, patient, and thorough in his explanations. What stands out most is their genuine concern for their patients’ well-being — he go above and beyond to ensure I understand my treatment options and feel confident in my care. The office is clean, efficient, and welcoming. Thank you Dr. Behzadi and Tri Valley team for excellent service.

Excellent Dr, caring, attentive as he listens to what I’m going through then provides a plan that will directly improve my way of life with freedom from pain!
Laura Sonoda, M.D.
Dr Sonoda does not explain the treatment and operation procedure clearly. She was amused by questioning the treatment / procedures which should lead to concerns for any patient.
Julie Long, M.D.
