Dr. Nickey Brown

Veterinarian & Practice Owner

I’ve always loved animals, science, and meeting new people, so it was an easy decision to dedicate my life to veterinary medicine. Each patient is important to me and I value the relationships that I build with their families. I focus on preventative medicine and like to think of my style as gentle, warm and caring. Trust is important in this line of work and I don’t take that lightly. While they’re in my care, your pet is as important to me as they are to you.
I have a wonderful husband, Tim, three great kids, and a house full of pets. Right now we have four dogs, one cat, two birds, and a brood of chickens. There’s never a dull moment.
“Be patient, be kind. We are all dealing with life in our own way”
