Dr. Jason Williamson DC


After receiving my doctorate from National University in Lombard Illinois, I moved back home to Michigan to practice. Having grown up in a small West Michigan town, I love practicing in Portland, as it reminds me of “home.” Prior to becoming a chiropractor, I graduated from WMU and was teaching and coaching in Northern Michigan.

Here, at Portland Family Chiropractic, I care for patients of all ages and have completed hundreds of hours of continuing education including extensive studies in pediatric and pregnancy care. I am a member various associations including the Michigan Association of Chiropractic (MAC). As a Portland resident I serve on the City of Portland Planning Commission and the DDA (Downtown Development Association). Being active is important to me, as I love hiking, biking and playing sports. Vicki and I married in 2017 and I am the very proud dad of 2 sons. Vicki and I also have 3 fur-babies, cats, Thumper, Casper and Sharpie.

“Through these doors walk the most important people in the world…our patients.”

Born and raised right here in Portland, I am proud to call Portland home. After graduating from Life College, in Marietta Georgia, I returned to Michigan and started practicing. Willemin Chiropractic, now Portland Family Chiropractic, opened and has been helping Portland and the surrounding communities ever since.

I have been married to my lovely wife Kathy for 39 years and have 3 wonderful children and 5 grandkids.
