Elliott Bettman, MD

I did my undergraduate work as a biology major at Wayne State University from 1978 – 1982. I attended the Universidad del Noreste from 1982 – 1986. After completing a Fifth Pathway at Lutheran Medical Center in Brooklyn, NY in 1989 – 1990, I did my medical residency at Saint Barnabas Medical Center in Livingston, NJ from 1990 – 1993. I became a diplomate in internal medicine in 1996 and have kept up my certification. In addition, I speak medical Spanish and have certification to give opiate replacement medications, including SUBOXONE®.

I worked at Gregory Medical Associates based in Passaic, NJ from 1994 – 1999 and had privileges at several local hospitals. After some locum tenens assignments, I worked at Health Care Partners in Conway, SC from 2005 – 2013. That is a state-run health center for uninsured and Medicaid patients. I then returned to the Detroit area to care for my late father and have been employed at WellHealth Medical Associates since 2014.
