Holly Brinegar

Hello, I’m Holly Brinegar, the receptionist and “go to” person for the team of Grant County Veterinary Clinic. I have been working with GCVC since 2007. While I don’t work on the technical side of animal care, I take great pride in strengthening the bond between pets and their owners. I enjoy getting to know our clients and their families.
