Mitchell Engle MD, PhD 

Interventional Pain Specialist

In a world of assembly line medical care, Dr. Engle is markedly different; he is passionate about his patients and helping them achieve wellness. Since every patient comes with a unique life story, he places particular emphasis on knowing and evaluating the whole patient. As such, he firmly believes that each patient must be individually assessed and given a unique treatment plan. He and the The Institute of Precision Pain Medicine staff will all diligently work to identify and treat the causes of pain rather than just masking it with more pills.
