Dr. Knowles decided at the age of 12 that he wanted to become a chiropractor. In 1990, he graduated from Western States Chiropractic College in Portland, Oregon. Upon returning to Boise, Dr. Knowles established Knowles Chiropractic and subsequently the Migraine Center of Boise, providing natural treatment for migraine headaches, tension headaches, and stress headaches. He has been helping those who were told "they would just have to live with it" for over three decades. When he is not helping people, Dr. Knowles loves to spend time with his family and being on the river fly fishing.
