A veterinarian in Millbrook, New York, John Jagar has been a member of the Zweig Committee since 1994.
It was on a friend's trainer's horse farm in Atlanta that Jagar was first drawn to veterinary medicine. Intrigued by the work of the equine veterinarian there, he decided that was the field he wanted to pursue.
After his sophomore year at the University of The South in Sewanee, Tennessee, Jagar worked as a groom on Claiborne Farm, which was owned by the family of a classmate. There he met veterinarians Colonel Floyd Sager and Jim Klyza, both alumni of the New York State College of Veterinary Medicine at Cornell; thanks to the impression they made on him, he decided that Cornell was the only veterinary school in the world to attend.
After earning a DVM degree in 1974 from Cornell, Jagar completed an internship and residency at Auburn University and received a master's degree in large-animal surgery. He returned to New York in 1980 to work as a resident veterinarian on a breeding farm in Ghent.
In 1984, with two partners, he opened a practice - Millbrook Equine Veterinary Clinic, P.C. - in the Hudson Valley, the hub of the New York horse breeding industry.
With his wife Suzanne, Jagar owns a Thoroughbred brood mare, a stallion share, and three dogs.
