Washington University

Michael Keith "Mike" Simpson, D.M.D. (born September 8, 1950 in Burley, Idaho), has been a Republican United States Representative from Idaho since 1999. Simpson represents Idaho's 2nd congressional district.

Simpson was educated at Utah State University in Logan, Utah, and the defunct Washington University School of Dental Medicine in St. Louis, Missouri. Simpson practiced dentistry in Blackfoot, Idaho, before entering the U.S. House. While other members of Congress who come from a medical background prefer to be referred to as "Doctor" while serving in Congress (most notably former Senate Majority Leader Bill Frist), Simpson does not insist that he be referred to as Dr. Simpson, preferring to simply go by Congressman or Mr. Simpson.
