Throughout Dr. Davey’s life, his pets have always been a part of the family. When he was young, they taught him responsibility and compassion and were a part of every childhood memory. As he grew older, they have always been loving companions and friends. So, when Dr. Davey was given the opportunity to attend Washington State University’s College of Veterinary Medicine, it was a dream come true. Since then, he has had the opportunity to practice medicine in Washington State, Colorado, Florida, and now Pennsylvania, and he is honored to share his passion for animals and to help other families share the same joy that he has with his pets. Dr. Davey’s favorite part of the workday is talking with people about their day-to-day life with their pets. Hearing about their adventures together, the daily laughs, the treats that get slipped under the table, their favorite toys, the valuables that they destroyed as puppies and kittens, and how they’ve changed over the years still makes him smile and laugh.
In Dr. Davey’s family he has two of the most bratty but wonderful cats, and the most spoiled little dog that you’ll ever meet. Caring for his own pets as they’ve grown older and developed medical conditions has given him perspective and understanding for helping others to care for their pets too.
What Dr. Davey finds most fulfilling about his work is empowering clients to provide the best possible care for their pets. There’s nothing he loves hearing more than “he’s acting like a puppy again” or “she’s been so much more loving recently” after starting a new treatment. Dr. Davey’s priority in caring for pets is to strengthen the bond that people share with their animals by helping all aspects of their care – from diet and behavior to medications and surgery, he wants to do everything he can to support their health and well-being.

Deb has been employed at GHAH since 2013 and has worked here as a Vet Assistant/Tech, Boarding Supervisor, Technical Staff Supervisor, Front Office Supervisor, and Practice Manager. In 2009, she officially entered veterinary medicine as a 2nd career and never looked back! She has found her true calling in this occupation and found a “forever home” at GHAH because she thrives in the culture of integrity and high standards that have always been a part of GHAH. Deb seeks to pass along calm and comfort to our animal patients and human clients at every opportunity and prides herself on understanding the many languages in which the pets speak to us!
Deb has 2 wonderful human children that fill her heart with pride and joy and, of course, a dog, cat, and some chickens just for fun. When Deb is not at the hospital, she is very likely spending time with her beau, Todd, or visiting one of her many pet-sitting charges.
Perhaps you will see her zooming through the lobby or speak to her on the phone at some point- she would love to help in any way she can!
