About Us

Dr. David James Crum

Dr. Crum realized his dream of becoming an equine veterinarian after working with both large and small animals growing up on a farm in western Pennsylvania. He attended Michigan State University in the Animal Science/Pre-veterinary program, then went on to attend and graduate from Kansas State University College of Veterinary Medicine in 1994. Dr. Crum worked at three distinctly different veterinary practices giving him valuable experience with Thoroughbred and Standardbred race horses, sport horses, Hunters and Jumpers, rodeo horses and backyard horses. Crum Equine Veterinary Service was founded in 1998 in Pickerington, Ohio. In 2002, the practice was moved to Lancaster, Ohio just a few miles southeast of Pickerington. Dr. Crum’s interests lie in sports medicine, lameness, reproduction and dentistry with an emphasis on lameness, diagnostics and performance sports medicine. Outside of work, Dr. Crum enjoys anything active outdoors and spending time with his wife and two young children.
