Meet The Off Leash K9 Team

Aundria Casarez - Trainer

Leading up to her career in training, Aundria worked as a bartender and dental assistant. But her love for animals took her career path in another direction.

Aundria is an El Paso native who loves the city and its community. She is a newlywed and enjoys working alongside her husband. Aundria has 5 dogs, all of which were rescued, and two snakes. In her free time, Aundria enjoys spending time with her family, reading, and training with her local Jeep community.


Mark Casarez - Trainer

Mark Casarez is an El Paso native who adores the city. Mark graduated from Sul Ross University with a bachelor’s in criminal justice. Before becoming a trainer, Mark worked with various law enforcement agencies.

Although he enjoyed his previous work, he has always had a passion for dogs and other animals, which led him to change his career path. He loves his 5 dogs, and two snakes. He enjoys working alongside his wife. In his free time, Mark enjoys bike riding, playing video games, and spending time with his family.

Brianna Flowers - Trainer

Before working at Off Leash, Brianna served as military police in the Army for 5 years at Fort Bliss. That was definitely the odd job she’s had, as she worked as a therapy dog handler from 2014-2017. Brianna also worked at a doggy daycare and volunteered for the El Paso humane society and El Paso animal services. She enjoys working with dogs more than anything.

Brianna and her wife, Jersey, have 4 dogs and two crazy cats! Brianna currently holds a canine psychology and behavior certification and hopes to help train dogs for work and sport in the future.
