Our History








History of Sifferlin Animal Clinic

Our history begins in 1966 when John F Sifferlin graduated from The OSU Veterinary School. He then took his family to Marysville, Oh to practice in a mixed animal Veterinary Practice. In 1968 he moved his family to Dover, Oh because of the large population of cattle and horses. He then established Sifferlin Animal Clinic and initially he was specifically a large animal Veterinarian and had no intention of practicing on small animals. But, as fate had it, future clients managed to find Dr Sifferlin on Wooster Ave, Dover Oh. They soon knocked on his back door in the evenings holding their sick dogs and cats. Little by little word got out he would diagnose and treat dogs or cats in the evenings (after his supper)….so began the line down his sidewalk that lead to the basement door. It became a family practice, Sue Sifferlin (wife) made a makeshift clinic in the basement and assisted in appointments with her husband. And with a continual support from the community the practice grew exponentially.

Soon in 1970 Dr Sifferlin bought property on State Route 39 NW and built which is now the current site of the practice. In 1972, he added on and doubled the size of his building. As the years went by, his practice evolved to be an exclusive small animal practice. He was a pioneer in our local veterinary community; in the early years he was the first one to purchase a “large animal truck”, he wrote in the Times Reporter, and his practice was featured in Veterinary Economics Magazine. He was widely respected by his peers and beloved by his clients and patients.

In 1986 Dr John F Sifferlin unexpectedly passed away. His practice continued with the support of his family, dedicated employees and loyal clients. In 1989 his daughter, Dr Sally Sifferlin, graduated from The OSU Veterinary School and came back home to practice at Sifferlin Animal Clinic. The practice continues to grow and evolve, which we are eternally grateful to the community for its support.
