Dr. Williams is a Board Certified Orthopedic Surgeon who specializes in Sports Medicine with a focus on innovative arthroscopic and reconstructive interventions for injuries affecting individuals of all ages. Ultimately, his goal is to get patients back to doing what they love, whether it is returning to the football field or chasing grandchildren around the park.

Throughout his life, Dr. Williams has always sought to become a leader in his field and has attended some of the top institutions for his education and training. As an undergraduate at Yale University, Dr. Williams studied political science and earned All-Ivy honors as a member of the varsity track and field team. Afterwards, he honed his research skills by working in a laboratory at Johns Hopkins Hospital. He then attended Harvard Medical School and completed orthopedic surgery residency at the prestigious Hospital for Special Surgery, which U.S. News and World report consistently ranks as the #1 orthopedic surgery hospital in the nation.

For additional specialized training in sports medicine, he completed a fellowship at the renowned Kerlan-Jobe Orthopedic Clinic. During his training he has had the opportunity to assist in the care of several professional sports teams including the Los Angeles Lakers, Los Angeles Dodgers, Los Angeles Kings, Anaheim Ducks, Los Angeles Sparks, and Los Angeles Galaxy. Additionally, he was assistant team physician for Loyola Marymount University Athletics as well as numerous high school football teams. He has written numerous scientific articles and book chapters on various sports medicine conditions and his award-winning research has been presented throughout the country and internationally. Dr. Williams utilizes the most up to date evidence-based surgical and non-surgical techniques to implement a comprehensive individual treatment plan for each patient emphasizing prevention of further injuries.

Dr. Williams is a member of the American Academy of Orthopedic Surgeons, the American Orthopedic Society for Sports Medicine, the Arthroscopy Association of North America, the J. Robert Gladden Orthopedic Society, and the National Medical Association.

In his free time, Dr. Williams enjoys spending time with his three young daughters Laila, Elise, and Aria, running with his wife Andrea, and listening to and collecting jazz records.
