Richard Pitcairn | Founder

richard 2009Richard Pitcairn, DVM, PhD graduated from the veterinary school at the University of California, Davis, in 1965. Entering private practice in Southern California, he worked with small animals, farm livestock and zoo animals. In 1967, he accepted a position at Washington State University, Pullman, Washington, as Assistant Professor, later entering graduate school with a major in microbiology and immunology and a minor in biochemistry. This was completed in 1972 with a PhD degree in microbiology. Following this, Dr. Pitcairn worked as a faculty member at WSU, active in research and teaching in the veterinary school.

During his research on the factors affecting natural resistance to disease, the importance of optimal nutrition became a focus in his work. Realizing that such research would not be funded, he re-entered private practice to apply his study of nutrition and its effect on immunity and thus resistance to disease. During the years of clinical work, Dr. Pitcairn, along with his wife Susan, in 1982 published the first edition of Dr. Pitcairn’s Complete Guide To Natural Health For Dogs and Cats. This book is now in its third edition and has sold over 400,000 copies and been translated into several languages.

A further development was a study of homeopathic medicine for animal application. Though nutrition is very important there are urgent situations for which nutritional therapy is not practical, also some patients that simply will not eat as part of their illness. Homeopathy is a natural system of medicine that stimulates the immune system and natural resistance to disease and from 1978 Dr. Pitcairn focused on learning and applying this system to use along with his prior knowledge of nutritional therapy.

In 1985, he moved to Eugene, Oregon to establish a practice devoted solely to use of homeopathy and nutritional therapy. During this time, from 1985 on, several workshops on homeopathic medicine were offered to the public and in 1992, the Professional Course in Veterinary Homeopathy was established, a year-long post-graduate training for veterinarians in the use of homeopathy in their practices. By 2013, 500 veterinarians have been trained in this program. During this time, in 1995, Dr. Pitcairn and associates co-founded the Academy of Veterinary Homeopathy, the first professional organization of practicing veterinary homeopaths in the United States.

More recently, Dr. Pitcairn, in association with Wendy Jensen DVM, has developed a veterinary repertory which is available in computer and book form. This is the major reference work that homeopathic practitioners use in their work with patients and this veterinary repertory is the first of its kind, focused specifically on veterinary practice. Now retired from active practice, Dr. Pitcairn consults with homeopathic veterinarians and continues to be active in teaching and writing in the area of homeopathic medicine and healing of disease.

She has presented each year at the Annual Meeting in Veterinary Homeopathy since 2012, on topics covering homeopathic practice management, case taking, and a variety of case studies including: canine behavior (noise sensitivity, fear aggression), developmental cases, canine mammary cancer, equine sarcoids, laminitis, and chronic thrush.

Todd Cooney

Todd Cooney website bio 186x224Todd Cooney, DVM, CVH was born and raised in Indiana, and trained at Purdue University for undergraduate studies and veterinary school. He worked in private practice, served as an officer in the US Air Force and Army, and worked as a USDA veterinarian. After almost twenty years of conventional practice, he took Dr. Richard Pitcairn’s Professional Course in Veterinary Homeopathy and changed the way he viewed health and disease. Dr. Cooney began to use homeopathy in his practice before he had even finished the course, and now uses it exclusively on all of his cases. Dr. Cooney is grateful to many great mentors along the way – Dr. Glen Dupree, Dr. Susan Beal, and Dr. Christina Chambreau, and of course, Dr. Richard Pitcairn. His practice keeps him busy in north central Indiana, as well as long distance consulting, and serving as one of the instructors for the Pitcairn Institute of Veterinary Homeopathy. Dr. Cooney has presented at numerous conferences including the PIVH Annual Meeting, Academy of Veterinary Homeopathy Conference, 2016 American Holistic Veterinary Medical Association Conference. He has published articles in the Journal of the American Holistic Veterinary Medical Association, Integrative Veterinary Care Journal, and Dogs Naturally magazine. Dr. Cooney is currently serving as the president of the Academy of Veterinary Homeopathy. After twenty plus years of conventional practice, he sees homeopathy as a much more elegant system of medicine; by being able to make deeper progress with cases of chronic disease through working with the life force of the animal to restore balance, thereby removing the disease of the patient at a deepest level instead of just masking the symptoms of ill-health.
