Dr. Clifford Les received his D.V.M. from the University of California-Davis, and then started a practice in the Trinity Alps of northwestern California, serving as the only full-time veterinarian within a 60-mile radius of Weaverville. He has taught anatomy and histology at the veterinary schools at MSU, and at the Universities of Illinois and California, receiving a Ph.D. in Comparative Pathology from UCD. Serving a postdoc- toral fellowship at NASA, he was then recruited to the Henry Ford Health System in Detroit, where he worked for 16 years as an NIH-funded basic-science researcher (working on post-menopausal osteoporosis) in the Department of Orthopaedics, and as one of the laboratory-animal veterinarians for the facility. He served the USDA (on loan to the United Kingdom and the European Union) as a field veterinarian during the 2001 Foot-and-Mouth Disease epidemic in northern England. In addition to his work with PetCalls, he also is the Chief Veterinary Officer for Innovative Health Technologies, a dental biotech startup firm in Detroit, and a biomechanics consultant for HOSSO, a Rhode Island firm developing an equine tendon rehabilitation device, as well as holding faculty positions at Wayne State University School of Medicine (Anatomy, Physiology, and Cell Biology), Oakland University (Physics), MSU College of Veterinary Medicine (Small Animal Clinical Sciences), Colorado State University College of Veterinary Medicine and Biomedical Sciences (Clinical Sciences), and Cal-Poly San Luis Obispo (Bioengineering). He is licensed in Michigan, California, and the UK, and lives in Birmingham with his wife Catherine (a Sterling Heights public librarian), and their three cats, Mariposa, Brighid, and Peg.
