She’s currently attending Texas State University getting her nursing degree, and later plans to go back to get her masters.

Nez Gomez, Kennel Tech
Nez is originally from Carrizo Springs but wanted to advance her education so she moved up state to get her degree in Dance Education. Nez was a kickbox instructor and dance teacher for a few years but her heart was missing her true passion, dogs! Since Nez was young, she always had the worst habit of taking in any dog that she saw on the road or that was offered to her. Her mission was to give every dog in her care the best life she could provide. Nez started her journey into the animal industry and worked in multiple areas ranging from vet clinics to grooming salons to try to learn all I she could! Nez saved every penny so she could purchase a few acres to build her own personal kennel for her pack of 7 rescues! There's not a thing Nez wouldn't do for her babies. Nez's personal goal is to have a beautiful space not only for her personal dogs, but also to take in more foster dogs and help any dogs that need some loving! Her career goals are to become a Canine Rehabilitation Therapist and continue to learn and grow with Jumping Jack! When not at work, Nez loves to cook, workout, and teach dance!
