About Eric Toennies

Chiropractor

I have always had a passion for facilitating optimal health through natural, noninvasive healthcare that emphasizes illness prevention. I’ve pursued chiropractic to restore health and increase the quality of life in the community.


While many professionals are treating the body from the outside in, my office treats the body from the inside out and lets the body be in balance to start healing properly. I look for, and most often times discover, the root cause of the problem. I do not treat symptoms.
