Who We Are

Clinic Director: Dr. Derik Anderson, DC, CSN, CPT

Dr. Anderson helps his patients be healthier by utilizing his education and personal and professional backgrounds. Dr. Anderson grew up wanting to help people and initially planned to go to business school to work in energy conservation. But, after a good friend’s life was positively changed by chiropractic care, he had a change of heart. His friend spent two years with horrific intestinal problems and saw over a dozen providers, but no one could help her – until she saw a chiropractor. The chiropractor knew that the vertebra and muscles around them affected the nerves that controlled the intestines. After treatment, she was no longer bed-ridden and went back to teaching, traveling and leading an active life. Dr. Anderson realized that health care was his calling and his passion for helping people was channeled into chiropractic.

Dr. Anderson lives what he practices. He is an avid runner, nationally competitive sailor, surfs, and is a youth coach. Dr. Anderson also eats a diet high in vegetables, low in starch, and drinks several quarts of water each day. Why? Food is our bodies’ fuel and muscles consume 70% of that fuel (the brain consumes another 20%), so to reach our maximum potential, our food chain needs to be clean, appropriate, and healthy for our needs.
