Kathleen Harder-Brouwer, MD

Kathi is also a native Michigander and met Dr. Brouwer at Wayne State University School of Medicine. After school, both doctors attended residency at Grand Rapids Family Practice Residency, in Grand Rapids Medicine. It was during residency that the doctors first visited the Indian Health Service (IHS) site on the Blackfeet Reservation that served as their first jobs. After a two year stint with the IHS, both doctors returned to Michigan so that Kathi could work as a faculty physician teaching residents in Grand Rapids. A mutual love of Montana drew them back and they were pleased to call the Bitterroot Valley home. Kathi is also board certified in family medicine and has a special interest in women’s and children’s health. Her hobbies include dancing, biking and being a mom. Larry and Kathi have two daughters, Megan and Zoe. Kathi also serves on the board of the Corvallis School District.
