Paul McClellan

President & Founder

Dr. Paul McClellan is a graduate of Purdue University School of Veterinary Medicine. It was his good fortune to have attended a university that placed a premium on instructors who were patient and devoted to their students. It was his friend Dr. William Henderson who introduced Dr. McClellan to the wonderful environment of Northern San Diego County. In 1982, shortly after receiving his veterinary degree, Dr. McClellan moved to the west coast. Performance horse medicine was a growing and rapidly evolving science for equine practitioners in the early ’80s and Dr. McClellan saw it as a perfect fit for his interests. He has devoted his entire career exclusively to the challenges of performance horse medicine.

The use of sophisticated technology to enhance indispensable clinical skills has been championed by Dr. McClellan. He was encouraged by his association with renowned radiologist Dr. Norm Rantanen to author several papers on the use of diagnostic ultrasound in the early ’80s. Dr. McClellan helped pioneer the use of standing MRI as a diagnostic standard for equine orthopedic injuries, hosting the first in North America at SDEG’s clinic in San Marcos. Dr. McClellan has shared his knowledge on this modality with the equine community since the early 2000s.

Dr. McClellan served on the USEF Drugs and Medications committee for 2 decades. He is an FEI permitted treating veterinarian and served as the 2020 USA Dressage Team Veterinarian, helping to bring home a Silver Medal for the United States! Through the years he has had the pleasure of working with horses at the highest levels of competition in multiple disciplines. The memories of great horses are never forgotten, even if he seems mystified by most everything else.

Together with Dr. Mike Manno, San Dieguito Equine Group has grown to be a globally recognized center for the orthopedic care of horses. Most importantly it is a business that values, mentorship, leadership, and teamwork as evidenced by the passionate and committed staff of San Dieguito Equine Group.

Aside from the pursuit of excellence in his vocation, Dr. McClellan’s interests include music, writing, and gardening. He stays physically and mentally fit by hiking with his canine companion Bernie and spending time with his Irish Sport Horse Toby.

Dr Nora H. Chavarria the newest edition to the SDEG team! She joins us primarily in the desert to help with the winter polo and sport horse show season.

When arriving at the WCVM she completed an internship in Large Animal Medicine and a combined Master’s and residency program in Equine Practice at the WCVM. At the end of her residency in 2012 she had her daughter and continued to stay on at the WCVM Equine Field Service Department as a clinical associate.

Dr. Chavarria’s husband is an avid polo player and spends every winter in Indio at the Polo club. Dr Chavarria has seen enough of Canadian prairie winters and has made a great effort to become a member of our team- at least for the winter seasons.

Dr. Chavarria is riding mainly English pleasure but has discovered Polocrosse, the “Poor man’s Polo”, together with a group of Polocrosse riders in Saskatoon. She owns an OTTB named Cherry, a typical red-head mare, who she says thought her a lot about approaching sensitive horses with patience and building trust.
