Phyllidia Ku-Ruth, MD


My name is Phyllidia Ku-Ruth. I’m an internist – I specialize in adult medicine. I was born and raised in Philadelphia and have lived in Maine since 1997 after finishing my undergraduate work at Brown University in 1993 and then medical school, also at Brown, in 1997. I finished my residency in internal medicine at the Maine Medical Center in 2000 and have been in private practice since then.

I have been with InterMed and in a job share with Sarah Subak-Krah, M.D. since 2004. It was an honor to be elected to serve as InterMed’s President in 2014.
