She enjoys working side-by-side with Doc Haviar and learning from his 30+ years of experience. When not working, her hobbies include tennis, horseback riding, and yoga.

Mallory, Veterinary Technician

I've spent my whole life with a huge love for animals and I can't imagine going a day without being around them. I've grown up with dogs and cats and was always the one to play nurse when an issue arose. I spent a few years focusing on school before I adopted my Border Collie, Addie. She is the love of my life and I'm so happy I found her.

I've been an avid horseback rider since I was 6 which is really what got me into the care and maintenance of the animal world. There's nothing like riding a trail with your dog at your side. Some things that I like to do in my free time are travel, spend time with family, and play with my dog.
