Kimberly Matzie, MD, FACS, FASCRS, is a board-certified colon and rectal surgeon at Fairfax Colon & Rectal Surgery, PC.
Dr. Matzie was born and raised in Granby, Connecticut. She decided to pursue a career in medicine after undergoing an operation in her freshman year of college. The procedure went well, but the surgeon didn’t have the best bedside manner, and no one on the surgical team explained the process or what to expect during recovery.
Dr. Matzie left the hospital inspired and committed to making interactions with her patients both positive and informative. After earning her undergraduate degree at Harvard College in Cambridge, Massachusetts, Dr. Matzie enrolled at the Perelman School of Medicine at the University of Pennsylvania in Philadelphia.
