Our Medical Director

Along with The Board, our Medical Director provides valuable insight into modern pet health products and services, ultimately deciding what products we carry at our Community Clinics, Wellness Centers, and in our Online Store.

Dr. Katryna Fleer

DVM, Medical Director

A researcher at heart, Dr. Fleer has worked with animals around the world. From the wilds of Africa and the meadows of Yosemite to zoos in California and New York, Dr. Fleer has studied animal health and disease transmission for the last decade. She also completed studies in broader public health issues concerning both humans and animals. Much of her work is still used by government agencies to help solve public health issues.

At VIP Petcare, Dr. Fleer is responsible for understanding the gold standard in preventative veterinary medicine and applying that standard to the company formulary and services offered. She makes sure on a daily basis that ViP Petcare offers the best possible quality of care to our clients and their furry family members. Dr. Fleer holds a B.S. in Zoology from Marshall University, a Masters of Preventative Veterinary Medicine and a Doctorate of Veterinary Medicine, both from the University of California, Davis, School of Veterinary Medicine.
