Meet Our Doctors

Dr. Mayo is married to Kevin (NOT a veterinarian!), and has four kids - Nathan, Joe, Rebecca and Gabriel. Additionally, they have many pets-dogs, cats and birds. She and her husband have a dream of eventually owning a small farm where they would be able to have goats, sheep and maybe pigs (that they would never eat!).
"Why do I come to work, why do I still love to do this job? Our veterinary teams at our two hospitals are the best people you can know, and together we make a difference every day. Whether it's a wellness exam for a new kitten, an emergency weekend surgery on an ill dog, or a school visit to teach kids (and teachers) about our amazing profession, every day holds a new challenge and a new reward."
