For nearly two decades, Dr. Heinen has been known for his expertise in shoulder and knee complex arthroscopy and joint replacement surgery. Now, he leads his Arcadia and Riverside team at the California Sports and Cartilage Institute with an emphasis to provide personalized, specialty Orthopaedic care.

Fellowship trained in Sports Medicine and double Board Certified in both Orthopaedic Surgery and Orthopaedic Sports Medicine, Dr. Heinen combines a scientific, literature based approach with common sense care. Honored as an Associate Master Instructor in shoulder arthroscopy teaching other orthopaedic surgeons nationally, Dr. Heinen has served for years as the “go to” shoulder and knee doctor of the Inland Empire and now also in Arcadia.

Having graduated top of his class from the University of California, Berkeley, Dr. Heinen pursued his medical degree at the Yale University School of Medicine in New Haven, Connecticut. He then received his Orthopaedic training at the University of Southern California Orthopaedic Surgery program.

Fellowship trained in Sports Medicine and Arthroscopy at SCOI, Dr. Heinen furthered his expertise in extremity care. He has been team doctor for multiple Division I, II and NAIA Universities for well over a decade. He continues to care for athletes at the University of California, Riverside; California Baptist University; California State University San Bernardino and La Sierra University. He also volunteers his time as team doctor of Loyola High School of Los Angeles, and as consultant for several other division I high school teams locally.

Academically inclined, Dr. Heinen is published in Orthopaedic peer reviewed scientific journals and also continues to actively teach others.

Dr. Heinen, his wife, Judy, and his 3 children, reside where he was raised, in the San Gabriel Valley, while still maintaining the valuable friendships developed in the Inland Empire.
