Bill W. Benson, DVM
Chief of Staff

A small town boy, Dr. Benson was born and raised in Hampton, Arkansas. After graduating from the University of Arkansas in 1978 with a B.S in Biology, he decided to pursue his lifelong interest in veterinary medicine at Tuskegee University School of Veterinary Medicine. In 1982 he graduated with his DVM degree. Seduced by what he thought was a mild winter climate, Dr. Benson moved to Maryland in January of 1984, now residing close by in Pennsylvania.

In 1990, Dr. Benson opened the practice in Reisterstown, Maryland. He is a committed veterinarian/surgeon and cares for all his patients with the same enthusiasm. Among his clients are Greyhound Pets of America of Maryland, the German Shepherd, Greyhound, Bulldog and Cocker rescues of Maryland who place their trust in Dr. Benson and his staff to provide the care and services needed to prepare the pets for new homes. His specialties are orthopedic and soft tissue surgeries. 

He is an avid Baltimore Ravens and Orioles fan and can often be found at M&T Stadium or Camden Yards rooting for the home team. Recently, his interest in thoroughbred racehorses will find him at any one of the local horsetracks or at his farm training his own farm bred foals and yearlings.
