Meet our Doctors

Jenni Zambriski, DVM, PhD

Staff Veterinarian

Emergency & Critical Care

I grew up in South Florida where I spent much of my childhood at the beach and surrounded by incredible wildlife, which sparked my initial love of animals. As soon as my dad told me that “animal doctor” was a real job, I knew that’s what I had to do! I went on to become a veterinarian and discovered a passion for epidemiology and infectious disease, earning my PhD. This has lead to a varied and amazing career path, which is one of the best gifts of this profession. As a veterinarian and epidemiologist, I have worked for the United Nations and many other great organizations, where I lived in Indonesia, Peru, Ethiopia, and Bolivia. I have also served as a professor in the College of Veterinary Medicine for Washington State University and Virginia Tech, teaching the next generation of veterinarians and public health professionals. All the while, I have continued to practice my first love, emergency medicine. In my free time, you most often can find me hanging out with my small petting zoo – Sammy the Wonder Dog, LaTiDa aka corgi-licious, my cat, Roberto Handsome Paws, and my bunny, Cupcake. I love cooking, traveling, knitting in the winter, live music, and all sports on the water…but prefer the ones where I can just float and look at pretty things!
