Brenna Zapata,
Veterinary Technician

Brenna knew she wanted to work with animals since she was five years old and began her career working them as a high school senior. She was hired to work as a kennel assistant while attending New Technology High and once her internship was complete; she continued to work there for ten and a half years. She reached her goal of learning all she could on the job and became promoted to veterinary technician.   Brenna and her husband are high school sweethearts and bought their house at 19 years old together. This gave them the opportunity to fill their house with a variety of animals of both fur and scale type. November 5th 2020 they welcomed their first baby to the crew. They are both excited for the future and love to be surrounded by animals and can’t wait to share that love with our baby who is already obsessed with the cats and dogs.
