Jeffery R. Jamison, DO, FAAFP


Dr. of Osteopathic Medicine


Dr. Jamison earned his bachelor’s degree from Brigham Young University in 1986, with a degree in Zoology, pre-professional, with an emphasis in Human Anatomy and Japanese. As a child, Jeff dreamt of becoming a doctor and helping people overcome their medical trials. However, after graduation, he chose to take time off from school, get married and start a family. Jeff and Trisha were married in 1987, and together they have 6 children. Jeff started medical school in Des Moines, IA, at Des Moines University School of Osteopathic Medicine in 1991.

After graduating in 1995, the family moved closer to their hometown of Spokane, Washington and began a residency in Family Medicine at Yakima’s Central Washington Family Medicine. He graduated, became board certified in Family Practice, and started a private group practice in 1998. He has worked in Spokane ever since.

Jeff has enjoyed a successful, high-volume practice. In 2004, he broke out on his own, running the practice by managing both medicine and business. He began his interest in wellness when he noticed that his office was full of patients who came to be ‘fixed’ without any thought to how they lived their lives or taking responsibility for their own actions. He felt he was missing something in the prevention piece of medicine. After cancer took his father’s life, Jeff resolved to work toward prevention of disease and not just treatment.

Prevention and wellness have always been a focus of his wife, Trisha. Once Jeff came on board with Trisha and recognized the value in prevention, fostering change, and focusing on real nutrition and brain neurobiology, the scientist in Jeff was in with both feet. Hard science and the holistic approach merged, and a calling in wellness was born.
