South Putnam Animal Hospital

Meet Our Doctors

Our approach to veterinary care sets us apart from other practices in the area. While we provide top-quality clinical services and feline boarding accommodations in a modern facility, it's how we deliver care to you and your pet that's different. We view bedside manner as an integral component of superior service, and strive to offer plenty of love, cuddles, and warm welcomes during every visit.

Jessica Hillyard

DVM

Dr. Jessica Hillyard is a Veterinarian at South Putnam Animal Hospital. She earned her Doctorate of Veterinary Medicine from the University of Minnesota College of Veterinary Medicine in 2013, and completed her undergrad degree from Northwestern University in 2005. Her areas of professional interest include surgery and oncology. Dr. Hillyard loves the human and animal bond, which inspired her to pursue a veterinary career back in 2007. She says the best part of working in the veterinary field is watching clients’ pets grow from puppies and kittens, to adults.

Originally from Oceanside, New York (Long Island), Dr. Hillyard currently lives with her spouse, Boxer, Steve, French Bulldog/Boston Terrier mix, Gizmo, Jack Russel Terrier, Bowser, cat, Trashy, and 9 hens. In her spare time she enjoys reading, doing yoga, and hanging out with her dogs. A fun fact about Dr. Hillyard is that she was an English major in college and has lived in four states, while practicing veterinary medicine in three of them!

Kathi Heiber

DVM & Co-Owner

Originally from Cleveland, Dr. Kathi Heiber earned her degree in veterinary medicine from the Ohio State University College of Veterinary Medicine in 1979. Her first few years in practice in Brewster, NY were spent treating companion pets as well as farm animals and horses.

In 1984, Drs. Heiber and Cindy Kosacz founded South Putnam Animal Hospital in its present location in Mahopac, NY. The hospital was built to provide a high standard of veterinary care that they would want for their friends and family to receive for their beloved pets. Providing owners with the best information to make care decisions for their pets has always been the hospital's goal.

Dr. Heiber is actively involved in the community, and presently serves on the Board of Directors for Cornell Cooperative Extension of Putnam County. She is also a leader with 4-H youth development programs that work with local youth interested in veterinary medicine. In addition, Dr. Heiber volunteers for AFS International Exchange Student Program welcoming students from foreign countries and supporting families who host students in their homes.

When Dr. Heiber is not practicing high-quality animal medicine or doing community service, you may find her riding her Arab Shagya mare, Lily. She also has a Jack Russell mix and two adopted cats. Dr. Heiber enjoys reading, swimming, yoga, and spending time with her husband, cooking through the seasons with fresh local produce, exploring new cuisines, and traveling.
