Dr. William Leonard "Bill" Vandergrift

December 8, 1954 — February 9, 2022

“There is a time for everything, and a season for every activity under the heavens.” This verse in Ecclesiastes 3 defines the life of Dr. Bill Vandergrift. Dr. William (Bill) Leonard Vandergrift of Elko, Georgia passed away on Wednesday, February 9, 2022 in a farm accident.

Bill, a native of Pittsfield, Massachusetts, was born to the late Rita Robenstein Vandergrift and Wayne James Vandergrift on December 8, 1954. He received his education in the Pittsfield schools and graduated with a Bachelor of Science degree in Horse Production from the University of Massachusetts in 1976. During his youth, Bill was involved in alpine skiing, as well as developing his musical talents of guitar playing and singing.

In 1976, realizing he had a dream to continue in the study of animal health, Bill chose to attend Texas A & M University where he obtained his Masters Degree (1978) and Ph. D. degree (1981) in Animal Nutrition. Upon his graduation, Bill accepted a teaching position at the University of Georgia where he taught courses in animal nutrition and also conducted research on the effects of animal nutrition on metabolic profiles. While finding this work interesting, Bill decided to leave the world of academia and accept a position as the Director of Equine Nutrition for Manna Pro in 1984 where he worked until starting his own company, EquiVision, Inc., in 1992. This company fulfilled Bill’s passion of not only providing quality animal nutrition in the United States but provided him the opportunity to work internationally with horse farms, owners and trainers. Dr. Bill was always on the cutting edge of equine nutrition often being the first to present a new concept or theory or develop a novel supplement. This work allowed others to know Bill as an animal nutritionist and as a caring and compassionate human who demonstrated his intelligence in a professional manner while serving with humility. Bill’s vast experience helped his clients win Olympic medals and major international races, including the Dubai World Cup, the Melbourne Cup, the Japan Derby and all three legs of the North American Triple Crown series. He was just as thrilled when any of his clients were able to accomplish what they dreamed of with their horses.

Continuing to lead EquiVision, Inc., Bill also consulted with Triple Crown Feed from the beginning of this company to the present time and was always a cherished member of this family. Throughout all of these professional experiences, Bill continued to make life long friends with many of his colleagues and clients, many of them calling him, “Dr. Bill”. Throughout his years as the owner and operator of EquiVision, Inc., Bill developed an extensive line of nutritional supplements and nutraceuticals that helped his clients’ horses reach their maximum potential. EquiVision, Inc., was awarded the Petfood and Nutrition Innovation Award in 2015, which was one of the many highlights of Bill’s professional career. As one client stated “Dr. Bill’s imprint on the equine industry will not fade” and another colleague said “I have never met a man so brilliant that was so humble” and yet another said “words simply can’t explain his role in life or his love for his wife, his friends, or those he just met, and his God.”

In 2001, Bill married the love of his life, Janice, and together they worked to increase productivity of EquiVision, Inc., and expand the territory in which the nutritional supplements were available. Bill and Janice moved to Kentucky during the early years of their marriage to allow Bill the opportunity to train racehorses and be immersed in the Horse Capital of the World. This time proved to be beneficial to Bill as he was able to interact and collaborate with some of the best professionals in the horse industry. He also set a track record with one of their own racehorses, as well as showed one of their horses to a World Title in Halter. It was during this time in Kentucky that Bill pursued his interest in farrier work. This work gave him the ability to treat the feet of horses and advance to becoming a certified farrier. His dream was to continue the farrier work and increase in his levels of certification while providing professional assistance to other owners of horses.

After returning to Georgia, Bill and Janice made the decision to sell the supplement part of EquiVision, Inc. to Stride Animal Health in 2018 so they could focus on developing the farm they purchased in Houston County and enjoy the horses that both of them loved. It was on this farm that Bill found joy and happiness in planning, designing and developing areas for their horses. Bill had a true passion for animal nutrition; it was never just a job. He also had a love for dogs especially Great Pyrenees. He and Janice fostered for National Great Pyrenees Rescue. This love of dogs and horses continued until his death.

Bill is survived by his wife of 20 years, Janice Satterfield Vandergrift, son Matthew Tyler Vandergrift of Macon, Ga., daughter Casey Lane Vandergrift of Asheville, N.C., siblings, Christine Lusignan (David) of Houston, TX, Carol Middelberg (Ted) of Austin, TX, James Vandergrift (Ann) of Seattle, WA, sister-in-law, Linda Corbett (Jim) of Atlanta, brother-in-law, Dr. Stephen Mason of Perry, GA and father-in-law, Courtney Mason of Perry, GA. Also, Bill is survived by 3 nephews and 4 nieces, 2 great nephews and 2 great nieces, as well as a host of close friends in Georgia and across the country. Bill was predeceased by his parents. Bill’s life demonstrated his love of God through his humility and his faith in his actions. Bill studied his Bible daily while reading other religious literature to grow his knowledge. Reflecting upon the life of Dr. Bill Vandergrift, there was a time for everything that included education and work and a season for all things in his life which included the many people he cherished in his life.
