About the Veterinarians

Dr. Robert Silver

Dr. Robert Silver DVM, MS, CVA achieved his lifetime goal of becoming a veterinarian when he graduated from Colorado State University’s (CSU) College of Veterinary Medicine in 1982. This followed his receiving his BS in Animal Science in 1974 and his MS in cardiopulmonary physiology in 1976, these also from CSU.

Veterinary College was an exciting experience for Dr. Silver, who enjoyed learning about the complicated diseases that our pets can get, and the many approaches available to address those diseases. He was active on the student newspaper, and involved in a number of projects, including one that involved bottle-feeding orphaned goats!

Following veterinary school, Dr. Silver practiced small animal medicine in Denver and Boulder and then spent a year teaching veterinary technology (nursing) in the mountains at Colorado Mountain College in Glenwood Springs. Following that, Dr. Silver moved to Colorado Springs where he established one of the first house call practices in the state, and there, in Colorado Springs, in 1984, is where he began his studies and his practice of herbal, nutritional, and holistic medicine for pets. At that time he started to learn acupuncture, studying first with Jake Fratkin, in Boulder, and then with the International Acupuncture Society, receiving his certification in 1993. In 1993, Dr. Silver moved his veterinary practice to Boulder, Colorado, where he established the Holistic Wellness Center, which later became known as Boulder’s Natural Animal, one of the first integrative veterinary practices in the country. Boulder’s Natural Animal was a “flagship” example of how blending conventional with alternative veterinary medicine can create superior clinical outcomes than either one of those modalities alone.

At Boulder’s Natural Animal, Dr. Silver commonly saw the really difficult cases that other practices would refer to him for his integrative approach. At Boulder’s Natural Animal, Dr. Silver established effective protocols for a number of serious, potentially life-threatening chronic diseases in dogs and cats, such as cancer, allergies, chronic pain, inflammatory bowel disease, Canine epilepsy, and behavior problems. In 1996, Dr. Silver began designing nutritional and herbal formulas for RxVitamins for Pets, a company that manufactures very high quality and high potency professional-level nutraceuticals for use by veterinarians to help their patients get better faster. RxVitamins has grown over the years and is now in 15 countries globally, as well as the US and Canada. All of these formulas are supported by evidence and research and have set the high water mark for professional quality animal nutraceuticals.

Dr. Silver writes extensive documentation for these formulas, and travels widely, both domestically and internationally, speaking to veterinarians and pet owners explaining the virtues of integrative medicine and how his formulas can help veterinarians better treat their patients for condition-specific clinical problems.As a veterinarian in practice in Colorado, Dr. Silver has directly worked with pets who have been given cannabis and hemp by their owners to address a number of difficult conditions such as epilepsy, pain, cancer and behavior problems. This experience has given Dr. Silver a unique understanding of this exciting emerging therapy in the United States.

Dr. Silver has lived in the Boulder area for over 20 years, enjoying the beautiful views and outdoor recreational opportunities for hiking, camping, biking, skiing, and sailing. In his spare time, Dr. Silver plays guitar and is a follower of Bluegrass music as well as blues and jazz.

Dr. Silver cooked professionally in New York City at a health food restaurant in the late 1960s. His background in cooking and his interest in natural nutrition have combined to make Dr. Silver very proficient at recommending and teaching the details of home-made meals for his clients to prepare for their pets. Dr. Silver has recommended home-prepared meals for his patients for the past 25 years of his more than 30-year practice of veterinary medicine.

Although retired from day-to-day practice, Dr. Silver still consults on difficult cases referred from veterinarians and continues to work as Chief Medical Officer for RxVitamins for Pets, designing formulas and educating veterinarians about the value of integrative medicine. Dr. Silver is also actively working with the medical hemp industry to bring quality CBD extracts to veterinarians and pet parents, alike.

Dr. Joyce Harman

Dr. Joyce Harman graduated from Virginia Maryland Regional College of Veterinary Medicine in 1984 with an interest in acupuncture and alternative medicine. She went to England then Ireland to study equine exercise physiology and sports medicine, always looking for a better, safer way to treat and train horses.

Upon her return to the United States, she went to work in New Jersey for a large equine practice, with all the latest equipment. However, as Dr. Harman began to find out, many animals still could not be helped and she began to use acupuncture extensively to resolve cases that were not responding to conventional medicine. Dr. Harman became a Certified Veterinary Acupuncturist in 1990.

She decided to open her own practice and do just acupuncture, so she moved to Virginia in 1990 and opened Harmany Equine Clinic. In 1994 she became a Certified Veterinary Chiropractor and also completed an advanced homeopathic course for veterinarians. Along the way, she has taken many other courses in holistic medicine for animals.

Dr. Harman finds the best approach for the horse is a team approach involving veterinarians, therapists, farriers, dentists, riding instructors, and saddle experts. She became the first veterinarian to acquire a computerized saddle-fitting device and is currently using the Pliance unit. This equipment gives a color scan of the pressure points under as saddle while the horse is being ridden at all gaits.

She has “written the book” on saddle fitting, with two volumes, The Horse’s Pain-Free Back and Saddle Fit Book for western and English horses. She also has a booklet to help introduce people to homeopathy for horses, The First Aid Guide to Homeopathy for Horses. Her goal is to help educate the equine industry about natural, holistic, and integrative medicine.

She writes extensively in both the lay and professional magazines and also speaks to both groups frequently. She has published over sixty articles in professional journals and more than that in lay magazines. A number of equine magazines have also featured her work and she is a regular contributor to “ask the vet” on http://equisearch.com/resources/expert/. She was president of the American Holistic Veterinary Medical Association in 1998 and 1999, the president of the Veterinary Botanical Medicine Association from 2006-2008.

In what little spare time can be found, she has a Connemara-Thoroughbred mare that she rides, drives, and enjoys. She is also a nature photographer and her work can be found at www.harmanyinnature.com
