Marcus worked the first ten years of his professional career as an Architect but then discovered the fascinating and complex dynamics of human architecture and so switched professions to a Doctor of Physical therapy. Marcus furthered his studies to become certified as an orthopedic specialist working as a director of an outpatient orthopedic clinic for St. Luke's University Health Network.
While Marcus has retired from Physical Therapy, he continues to work with architecture and construction part-time. He also teaches skiing in the winter and enjoys mountain climbing and bicycling - both mountain and road biking.
