The Mack Clayton endowed lecture series is a monthly seminar that features distinguished speakers from outside institutions, who are nominated by trainees and faculty. These speakers are invited to CU to present their latest research in musculoskeletal science during a one-hour seminar. Their visit also includes one-on-one meetings with faculty and their labs across the Anschutz, Denver, Colorado Springs, and Boulder campuses, held both in person and virtually. Most importantly, there is a "meet-the-professor" session following the presentation. This session gives trainees the chance to network with established researchers, ask questions about their work and careers, and ultimately expand their professional connections.

The history of the Mack Clayton Lectureship is supported by the Dr. Mack Clayton Endowment in the Department of Orthopedics at the University of Colorado. Dr. Clayton was a clinician and surgeon-researcher who focused on developing surgical and biological methods to accelerate ligament healing in the 1950s. His pioneering work led to significant advances that laid the groundwork for the modern treatment of ACL injuries. He was well-known in the ski communities around Denver and along the Front Range for creating medically trained ski patrols, which were the first to provide orthopedic and trauma care to injured skiers on the mountain.
