Brynn Bixby
Physician Assistant
I grew up south of Musselshell at Meredith Ranch and went to high school in Custer. I received a Bachelor of Science in Biology and Chemistry. Then went to Rocky Mountain College to obtain a Master of Physician Assistant Studies. I have worked in the medical field for 18 years now and truly love it. I am married with two rambunctious boys, Blake and Zane. They are the center of my life. We have a fish named Iron Man. I enjoy all sports and outdoor activities. I am very interested in orthopedics and sports medicine.
