About the Office Staff

Dr. Joan M. Johnson DC
      Chiropractic Physician
National College of Chiropractic

As a child, she suffered with migraine headaches.  She missed entire days from school from age five on.  As a teen, traditional medicine failed to improve her symptoms.  In college, after several specialist couldn't make a difference she tried chiropractic care and within three weeks she was seeing improvement for the first time in her life.  Six months later she graduated from Hood College with her bachelors in Biology and was enrolled in National College of Chiropractic in Lombard Illinois to start her own journey spurred on by her successful treatment.

Diana grew up in this Chain of Lake town of Antioch, though she moved away to the South to raise her kids, she returned to be near her family and has worked for AFC for almost the entire life of the practice.  In the 28th year of the practice, she decided to cut back to part-time and she now works from home, taking care of the insurance and billing aspect of the office.  Though we miss her face in the office (staff and patients alike) she has more time for her granddaughters, Mom, dog and cats and of course her plants and baking!
