Developed by Dr. William Barnett, DVM
Founder of Advanced Veterinary Nutrition
Since 1982, he has used his skills and knowledge to develop supplements that promote optimum fitness and health in both dogs and cats. Dr. Barnett received his Doctor of Veterinary Medicine degree from Iowa State College of Veterinary Medicine. After graduating, he enrolled in the Laboratory Animal Medicine and Surgery program at the Walter Reed Army Institute of Medical Research. Here, as acting veterinarian, he presided over the daily medical and surgical care of more than 13,000 animals. Over the next four years, Dr. Barnett was appointed special advisor to the US Army Dental Institute of Research and the Walter Reed Division of Surgical Research. Dr. Barnett also served eight years as the Head of Surgical Research at the Clinical Investigation Department, Naval Regional Medical Center in San Diego.
Dr. Barnett’s experience and careful attention to the specific health needs of animals throughout all stages of life has led to the development of a line of products that are safe, effective, palatable, and maximize the full potential of the dog and cat – allowing them to live healthier and longer lives.
