About Longmont Joint & Spine

Longmont Joint & Spine was established in 2016 with a mission to provide the highest quality musculoskeletal care at reasonable prices. We don’t believe in the practice of multiple visits per week for many months at a time. There are no sales pitches or drawn out timelines here. We’re just real people trying to keep our friends and neighbors feeling their best without breaking the bank. Our goal is always to provide significant relief as soon as physically possible in hopes that you will spread the word about our services.

Micheal Walker, D.C.

Owner/Clinic Director

Dr. Walker was born and raised in Southern Illinois, just outside of St. Louis, Missouri. He has been a Longmont resident since 2013 and hopes to be active member of the community for decades to come. He is an avid sports enthusiast. In fact, some might say his baseball (St. Louis Cardinals) obsession is borderline unhealthy. Outside of work he enjoys live music, craft beer, and travelling.
