DR. JILL GREISMAN
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. JESSIE BOLSTER
Skill and patience are what Jessie Bolster brings to the table as one of our two owners. Dr. Jessie has a passion for equine podiatry, pastured beef, and alternative/organic treatment methods. She enjoys formulating herd health plans and looking for low cost, effective treatments to decrease the frequency of sick animals in the herd. In her free time, she and her husband raise grassfed beef and pastured pork.
DR. RHEANNA FOLEY
Dr. Rheanna Foley, the newest member of the team, is excited to be back in New York joining Dr. Jill and Dr. Jessie at RVVS. 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. ALEX FITTON
Say hi and welcome to Dr. Alex! You may recognize her from one of the times she has worked with us in the past 3 years.
Dr. Alex Fitton, the newest member of the RVVS team, is excited to serve any animal on your farm! A Hudson Valley native, she’s thrilled to be back in upstate New York after finishing her Doctorate of Veterinary Medicine and Bachelor’s of Animal Science at North Carolina State University. She worked previously at Advanced Animal Diagnostics, a company which develops diagnostic technology specifically for food animals, and as a clinical pathology laboratory technician. Dr. Alex has a background and interest in working with many animal species including: equine sports medicine, dairy cattle pharmacology research, and backyard poultry flock health.
In her spare time, Dr. Alex enjoys horseback riding with her off-the-track-Thoroughbred (Marshall), hiking with her dogs (Rue and Rogue), gardening with her house chicken (Margie), and breeding Belgian d’Anver bantam chickens.
After graduating from Cornell University in 2014 with a degree in Animal Science Emily became an assistant manager at a 1200 cow dairy farm. From that farm, she transitioned to managing a 500 cow dairy. Now a full time mom to 3 energetic kiddos ages 3.5, 2 and 6 months, she gets to spend her "free time" on raising her own animals including a small number of beef cows, honey bees, and meat/laying chickens. Emily answers phones and responds to emails for RVVS and is an integral part of our team. When she can, she'll jump in the truck to meet clients face to face!

Veterinary Assistant / Office Staff
Allie Bellair is one of the newest additions to the team and couldn’t be more excited to help out. She graduated from Union College in 2020 with a degree in Chinese language and minor in Mathematics. She is currently finishing up her pre-requisite courses through UVM’s post-baccalaureate premedical program so that she can apply to veterinary school in the next couple of years. Although new to large animal medicine, Allie has quite a bit of experience working with small animals. When she isn’t answering the phones, she is usually riding along with one of the doctors to learn anything she can about large animal medicine as this is what she hopes to do one day!
