I completed a research fellowship and colon and rectal surgery residency at Ferguson Hospital on the Grand Rapids and East Lansing campuses of MSU. I am board certified in general surgery and colon and rectal surgery. I am a fellow in the American College of Surgeons and the American Society of Colon and Rectal Surgeons.
