Dr. Mark Revenaugh is the owner of NWEP. He is a renowned expert in the diagnosis and treatment of lameness and performance issues, attracting clients from all over the northwest. His fascination with equine medicine and competitive performance began long before opening his specialty clinic in the Oregon.
Though he studied riding under eventing icon Bruce Davidson, and spent several years in human medical research, his passion was always focused on helping owners and horses maximize their performance potential.
He pursued that passion at the University of Illinois College of Veterinary Medicine, graduating in 1991. Dr. Revenaugh worked with some of the leading sport horse veterinarians in the world, including Dr. Kent Allen, Dr. Haynes Stevens, and Dr. Brendon Furlong. During this time, Dr. Revenaugh authored the first license for use of scintigraphy (bone scan) in the state of New Jersey in 1996. In 1997, Dr. Revenaugh took his first trip as official USET Team Veterinarian, traveling to Germany for a pairs Driving World Championship. Dr. Revenaugh has been honored to serve as a Team Veterinarian or Assistant Team Veterinarian since that time. Duties have included selecting, treating and advising elite level professionals in the equine industry, maintaining health and maximizing performance.
Dr. Revenaugh moved to the Pacific Northwest in 2002 where he intended to create a small and unique practice to work exclusively with equine performance issues and lameness. The clinic quickly grew into one of the premier equine sports medicine practices in the western United States reflecting Dr. Revenaugh's investment in advanced technologies, imaging modalities, and leading edge therapies. Dr. Revenaugh has also served as the Director of the High Performance Sports Group since 2013 in an effort to help further not only the sport, but the profession as well.
His greatest professional joy remains being part of a winning team; helping horses and owners make good decisions to advance equine health and maximize performance.
Dr. Revenaugh lives on a farm in Mulino with his wife and 2 children. They enjoy outdoor activities including bicycling, camping, and exploring this beautiful region.
