In 1985, Dr. Pitcairn moved to Eugene, Oregon to establish a practice devoted solely to the use of homeopathy and nutritional therapy. From this time forward, 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. As of 2016, over 500 veterinarians have been trained in this program offered by the Pitcairn Institute of Veterinary Homeopathy. 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.
