“I try to be mindful of the humanity of every patient I see. This involves learning the situational & physical stresses that impact the patient’s presenting problems and addressing these issues in my treatment plan. I am particularly interested in utilizing the newer advances in regenerative medicine to stimulate my patient’s natural repair mechanisms – with regard to damaged or inflamed joints, tendons, and ligaments.”
