About Dr. Crist  

Essentially, I am a Family Practice medical doctor whose primary focus is on patients with borreliosis or Masters Disease. This web site is designed to shed light on this very complex and serious illness. I practice in Columbia, Missouri, USA.

I am originally from Shelbina, Missouri. I attended medical school at the University of Missouri-Kansas City, and did my residency in Family Practice at St. John’s Mercy Medical Center in St. Louis, Missouri. After that I served three years on active duty in the United States Air Force and became an A-10 Flight Surgeon.

In 1988, after leaving the Air Force, I joined a group of medical doctors in Cape Girardeau, Missouri. The group included Edwin J. Masters, M.D., for whom Master’s disease is named. During the five years I practiced medicine with Dr. Masters, I became heavily involved with helping patients with Masters Disease, or more accurately with borreliosis. (Several different bacteria that are borrelia may cause this disease, so borreliosis is a better name.)
