Origins
Raised on a Farm:
Raised on a Farm:
A Foundation of Hard Work
I grew up on a fourth-generation family farm in Massachusetts, where long days, early mornings, and caring for animals were simply part of life. From feeding horses before school to helping with dogs, cats, ducks, rabbits, goats, and everything in between, those daily responsibilities shaped my work ethic and taught me the value of teamwork. It was on that farm that my love for animals truly began — a connection that has stayed with me throughout my life and makes supporting veterinary teams feel less like a job and more like who I am.
