I am a Board-Certified internist and for the past eighteen years I have been working full-time in Graduate Medical Education (GME) , academic medicine, as Program Director for an Internal Medicine residency. I completed my residency at University Medical Center in Las Vegas including a year as Chief Resident. In my last year, 1999 , I was given the Resident of the Year and the Out Patient Clinic Resident of the Year awards.
I have been providing my services as a part-time endeavor and now I'm ready to go full-time. Included among my many skills is the fact that I am very adept at picking apart other physician's expert opinions and do not hesitate to sharply criticize them. I have provided written opinions on cases that ranged from relatively straight forward to two inmate, in-custody deaths.
