JILL GREISMAN, DVM, cVMA
If you’re looking for intelligence and quick thinking, then let Jill Greisman manage your animal's health care. There isn't an animal on the farm that Dr. Jill won't treat, be it horse, cow, pig, or turkey Dr. Jill will sort out a solution quickly and efficiently. She is certified in acupuncture/manual manipulation and enjoys advising people on the best way to manage their farm health. When she isn't treating other people's animals she's riding one of her horses in summer shows.
Dr. Rheanna Foley
Dr. Rheanna is no stranger to hard work and will happily tackle (or treat) any issues with enthusiasm. She studied Animal and Dairy Science at Cornell University prior to attending veterinary school at Mississippi State University. After graduating from vet school in 2019, she worked in Virginia for over a year caring for a wide variety of farm animals and family pets.
Originally from Tyler County, WV, she and her two older brothers grew up together and could often be found out rambling the farm with the family dogs. Early on, she was an active member of her high school FFA chapter, participating in many career development events and raising hogs for the chapter’s annual Ham & Bacon Sale.
Now, in her spare time, Dr. Rheanna enjoys hiking, gardening, baking, and training her dog, Mia, to do cool tricks. Be sure to let her know the best places to go hiking and best places to grab coffee or lunch!

Dr. Mary Kate Metch
Dr. Mary Kate Metch grew up and went to college in Virginia. She worked in small animal clinics before attending veterinary school at the University of Pennsylvania.
