Dr. Jason Barker, NMD

Naturopathic Medical Doctor

Dr. Jason Barker is a Naturopathic Medical Doctor. He received his medical training from Bastyr University in Seattle, WA. Dr. Barker’s clinical focus is utilizing integrative medicine to help his patients.....

Integrative medicine includes the full spectrum of physical, emotional, mental, social, energetic, spiritual, and environmental factors that influence your health. Dr. Barker also takes the time to listen to his patients to understand their healthcare needs better. Dr. Barker is a member of the Medical Academy of Pediatric Special Needs (MedMAPS) and has extensive experience treating children on the Autism Spectrum. He also treats digestive disorders, anxiety and depression, Lyme disease and co-tick infections, auto-immune, allergies, and much more.

“What drew me to Naturopathic medicine was a desire to help people understand their health. People’s hardware is roughly the same. We all have hearts and brains, toes and fingers, blood and tears. Yet every one of us is different. We are shaped by our genetics, our experiences, and our environment. So treating everyone as an individual is the only way I see medicine working properly. I look forward to helping you understand your own health.
