Trisha Holder was raised on a 2.5 acre ranch with her parents and older sister, located on the far eastside of Mesa, Arizona. She grew up around horses which shortly developed into a very strong love for all animals. The love of animals guided her to go work for her neighbor, who was a dog breeder. For the next 10 years she helped in the kennel as needed. As the years went by Trisha began riding her horse at the local arenas competing in barrel racing, pole bending, and gymkhanas along with the local 4H club. She attended AAEC Red Mountain High School in 2008. During her second year of high school she became president of her schools FFA chapter, as well as an active member in the rodeo and horsemanship clubs.
Once out of high school, Trisha began working for a company as a caregiver for geriatric patients in their personal homes. She worked in human medicine for 4 years before changing careers completely by enrolling into the veterinary assistant and veterinary technician programs at Pima Medical Institute in 2018. She proudly graduated from both of the programs in 2019 with perfect attendance. With hard work and responsibility she gained over 480 hours of externship skills at a small animal hospital and equine hospital. This allowed the pursuit of her career as a mobile mixed veterinary technician.
