Leah J. Greenberger, DVM

Long ago in a small town in Pennsylvania a toddler rode on her bouncy horse and proudly told everyone she was going to be a "horse doctor" when she grew up. That little girl never lost sight of that goal. She earned her undergraduate degree and then her doctor of veterinary medicine in 1992 from Cornell University and is Dr. Leah Greenberger. Her path took her to Maryland and then Virginia where she operated a successful small animal practice in a rural area near Norfolk. Along the way she rescued, fostered, and adopted a legion of dogs and cats and developed her love of birds, reptiles, and other exotic animals. She never lost her love for horses and riding. When she moved to Massachusetts in 1999, she practiced emergency and critical care veterinary medicine throughout the area. These specialties developed her skills as a diagnostician and exposed her to a wide variety of medical experiences. Dr. Leah brings all of her background, love of animals, and experience to Belchertown Veterinary Hospital. She still retains her interest in emergency medicine and her longtime love of exotic animal medicine.

Faith attended Holyoke Community College and UMass Amherst, graduating with a degree in Biology. She minored in Criminal Justice and was certified as a veterinary technician in Connecticut. She served in the Army as an MP for 10 years. When asked about her current profession she states, "I love animal medicine. It is so fulfilling to be a part of the healing process and a part of the care. If I went back to school I would definitely pursue a career in animal and human communication. Each animal I encounter is so different and unique in the way they communicate. A touch from a purring cat or the depth of the stare of an old dog can warm my soul. Trust can be difficult sometimes, but once it is gained, unconditional love is certain." She has three cats, two dogs, and is a Yankees fan.
