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.

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.

As a colon and rectal surgeon, Dr. Matzie has special interests in Transanal Endoscopic Microsurgery (TEM), a minimally invasive approach to removing large rectal polyps and early cancers not responsive to colonoscopy excision or other traditional techniques.

When she isn’t at work, Dr. Matzie enjoys spending time with her husband, Chris, and their two daughters.
