Meet Our Team
Experienced, caring doctors dedicated to your well-being.
Matthew Hales
I founded Chiro Shack on a simple idea: chiropractic care should be accessible to every family — not just when the pain gets unbearable. I studied at Parker College of Chiropractic and have been adjusting patients ever since. My approach adapts to you — traditional hands-on, gentler techniques, whatever your body responds to best. Outside the office I’m a dad of six and a grandpa, so I know firsthand what it means to need affordable, reliable care for a whole family. Getting adjusted is a partnership. I’m glad you’re here.
Dr. Gary Spainhower
Dr. Spainhower brings skill, warmth, and dedication to the Middleton location. Patients love his thorough approach and personable care. He works alongside Dr. Hales to ensure every Middleton member receives the same high-quality adjustments.
Dr. Jim Marion
Dr. Marion is the chiropractor at Chiro Shack Treasure Valley. He came to this kind of practice for the same reason a lot of patients come to us: the chance to do real chiropractic care without the insurance maze, the long intake forms, or the upsell. He'll walk you through what he's seeing, do the work, check in on how it feels, and get you back to your day. New to chiropractic and a little nervous? That's normal — he'll explain everything before he does anything. Kids welcome.
Dr. Gregg Jones
Since 1995, Dr. Jones has specialized in treating patients who want to maintain and even improve their active lifestyles. A big fan of family and the great outdoors, Dr. Jones believes that age is not what limits us. It's our choices. Returning people to doing what they love and have lost is his greatest motivation.
