DR. BRIAN SIDES, DC 

Dr. Brian Sides grew up in southwest Missouri where he started playing soccer at the age of 4.  He grew to love the sport and it, in turn, took him all across the Midwest.  He never dreamed it would take him to college, but it did.  It was at Missouri State University where he learned the principles of chiropractic and saw the benefits of it.  He knew he wanted a career in the medical field, but was not certain which specialty until he got treated for an injury sustained while playing soccer.  The treating physician; a chiropractor.  Over the next several weeks, he discussed the basic values and principles that chiropractic was founded on and why health care must move towards chiropractic in order to fix the health care crisis.  From that moment on, Dr. Sides knew exactly where he was headed.  From there, he attended Logan College of Chiropractic, and spent many hours studying the human body and biomechanics.  Not only does he have a special interest in sports injuries, but the most satisfying thing is helping, not just athletes, but everyone “make it” to the next level.  Performance is the key, and he wants us all to perform at the peak of our capabilities. The only true way to do that is to make sure the body can move and function without interference or interruption.  His goal is to make this community a more active and healthier one.
