Dr. Dost Sarpel

Dr. Dost Sarpel completed his Internal Medicine Residency and Infectious Disease Fellowship at the George Washington University Hospital in Washington D.C.   After finishing his fellowship, Dr. Sarpel worked as consultant for many hospitals throughout the East Bay area in California.  During this time he was a key part in managing Infection Control and Antibiotic Stewardship programs at numerous hospitals and long term care facilities.  He then made the decision to pursue additional training because of his strong interest in viral hepatitis.  He completed a Viral Hepatology Fellowship under the mentorship of Dr. Douglas Dieterich, a world renowned hepatologist, at the Icahn School of Medicine at Mount Sinai.  Dr. Sarpel has noted expertise in treating patients with HIV, chronic hepatitis C, or chronic hepatitis B as well as patients with co-infection of these viruses, and has given many lectures on these topics.
