In recognition of the dedication and effort shown in helping to advance research in the Comparative Orthopaedic Laboratory in order to improve the quality of life for humans and animals, we present Dr. Robert and Mrs. Marilyn Littlejohn with the Making a Difference Award. This award recognizes their significant contributions to the COL through the years. The support, encouragement, and inspiration they have provided have been important to our development into a world leader in orthopaedic research. The Littlejohn Family Endowment ensures the success of Comparative Orthopaedics Day and the many associated benefits it brings to Mizzou. This award is intended to express our sincere gratitude and appreciation for the Littlejohns as an integral part of our team.
