Dr. Forstner is a board-certified colon and rectal surgeon, who has been part of a thriving female colon and rectal practice since returning to the Valley in 2006. She received training at Mayo Clinic Scottsdale after attending medical school at the Mayo Clinic in Rochester, MN, and received her specialized surgical training with the Colon and Rectal Clinic of Orlando.
