Dr. Jon Harmon

Certified Neurofeedback

As a young boy, Dr. Harmon received so much benefit from Chiropractic that he decided he wanted to be a Doctor of Chiropractic. This has always been his passion! He attended the University of Utah and has a BS degree in Human Biology. After graduating summa cum laude from the Los Angeles College of Chiropractic in 1989, he settled in Boise where he has been practicing ever since. After experiencing the severe family emotional trauma of the suicide of his eighteen-year-old niece in March of 2010, the murder of his eldest daughter’s husband in March of 2011, his younger daughters started to experience depression, anxiety and insomnia. Counseling and prescription drugs weren’t helping so he decided to find other therapies to help his family. This led to expanding his education and practice to serve individuals with Neurofeedback and his passion to help others. Dr Harmon is Board Certified in Neurofeedback by the BCIA the international standard in biofeedback certification for MDs, Ph.D.’s, Psychiatrists, DOs, DCs and all healthcare professionals.  He is married, father of eight children and grandfather of 21.  He enjoys working out, staying fit, eating healthy, writing poetry, composing songs and spending time with his family.

Dr. Jason Barker

Naturopathic doctor

Dr. Jason Barker is a Naturopathic 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.”
