Deb DeMott

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!
