Dr. Riggenbach joined Orlando Orthopaedic Center in 2012. He came to Orlando after spending the majority of his life in the midwest. He attended the University of Dayton where he majored in Exercise Science and worked as an assistant strength coach for the Dayton Flyers athletic department. It was there where he developed his interest for the musculoskeletal system. He graduated summa cum laude, winning several academic awards. He remained in Dayton, Ohio attending the Boonshoft School of Medicine at Wright State University where he became involved with Orthopaedic Surgery.

Upon graduation from medical school, Dr. Riggenbach completed his residency at the Ohio State University Medical Center. His interest in hand surgery began during long nights in the emergency room, caring for patients with hand injuries. This interest propelled him into a Hand/Upper Extremity Fellowship at the University of Florida Department of Orthopaedics.
