Samantha K. Engle, PA-C

Certified Physician Assistant

Samantha Engle is a Board Certified Physicians Assistant. Growing up as a competitive athlete Sam has always had a passion for Sports Medicine and Orthopedics. As a child, Sam often accompanied her Mother, who’s an Orthopedic Surgeon, on weekend rounds in the hospital. Seeing the impact that her Mom had on the lives of her patients, Sam had no doubt she would one day join a medical field.

Sam began that process at West Chester University, where she earned a B.S. in Exercise Science, then continued at Slippery Rock University, where she earned a Masters of Physician Assistant Studies.

Sam credits her years as a competitive athlete, including her career as a collegiate gymnast, with helping her appreciate the value of a work ethic, learn how to overcome adversity, and see the value of commitment to everything you do.

She brings that same drive, and that same passion for work, sports, fitness, and nutrition to CAO — where she plans to prove once again the truth of the adage, “There is no shortcut to success, and no substitute for hard work.”
