Christopher Johns, MD

Dr. Christopher Johns' deep desire to help others, along with a keen interest in biology and science helped him to realize that a career in medicine was in his future. He sustained an injury while playing ice hockey that showed him how significant functional limitations can impact your goals and quality of life.


Dr. Johns attended medical school at the University of Cincinnati in Ohio, where he stayed to complete his residency in Physical Medicine & Rehabilitation. He chose this specialty because he realized how important movement was to the overall health and physical, mental, and social well-being of every person, no matter the age or circumstance.


Dr. Christopher Johns believes in “the power of positivity and adherence to the golden rule”. His approach to care is to “treat your patients like family and remember that you are treating a person, not a symptom Everyone is unique and their medical plan should be tailored accordingly to provide for the best possible outcome.”
