Dr. Fiser grew up on a small family farm in Atwater, California. He attended UC Riverside, and graduated from UC Davis School of Veterinary Medicine in 1986. He has been with Lone Oak Large Animal Veterinary Services since graduation.

He currently resides in Visalia, California with his wife, who is also a veterinarian, and their two teenage children. Dr. Fiser spends most of his spare time with his family, which usually involves some type of sport: he can be found playing, coaching, and cheering on his kids in baseball and volleyball. He also enjoys spending time snow skiing and traveling to places of historical significance.


Brent Pascoe, D.V.M.

Dr. Pascoe was raised right here in Tulare County in the small town of Lemoncove.

He and his wife love to rope, hunt and fish with any spare time they have. You can also find him helping his in-laws who run a pack-station in the Eastern Sierras out of June Lake, California.
