Care Philosophy

This content was provided by Dr. Diamond "We believe that each patient touched with cancer has unique concerns, fears, aspirations, and personal dynamics.  We strive to address each of these.  We also understand that while quality of care is (and should be) of paramount concern, that cost of care is an important concern.  As an independent (ie, non-hospital affiliated) practice, we can offer best-of-care treatment at costs typically much lower than that of the local hospitals."
