Countryside's Veterinarians

Dr. J. Glenn Brewer

Dr. J. Glenn Brewer

University of Georgia


Countryside Founder and Janitor Emeritus (janitor of great merit)

Dr. Brewer bought the land and started blueprints for Countryside Animal Clinic in 1979. His first patient at Countryside was an Irish Setter named Jed in February 1982. Jed visited during the construction phase, waiting for opening day.
​​​​​​​
Dr. Brewer attended the University of Georgia for undergraduate and veterinary college. He furthered his training at the Animal Medical Center in New York City and owned Clearwater Animal Hospital before moving to Deland. Dr. Brewer and his wife are high school sweethearts from Madison, Georgia.

Over the years they have taken in a multitude of animals they call pets, such as cows, horses, goats, dogs, cats, and chickens. Their breakfast room furniture still has chew marks from teething puppies. Dr. Brewer says their first child was a cat, then they had human babies.

Dr. Brewer’s primary concern has always been the family owned pet and getting to know the family. “The Countryside family of employees are a part of the community. We love participating with the schools and civic organizations for the betterment of our hometown. Of course, there is nothing more rewarding than helping pets who can’t speak for themselves.”
