Mateo “Teo” Castaneda

Registered Behavior Technician - He/They


Teo has worked in the field of ABA since 2023, and has prior experience serving in the military and working in community outreach through the Big Brother mentoring program. He is originally from Houston, Texas and moved to Colorado in 2009.

His favorite thing about ABA is being able to be part of his client’s growth! In his words, “this line of work heals the soul and provides a sense of purpose, while teaching with the love and care necessary to impart growth.” In his free time he enjoys playing pool, playing Magic the Gathering and Dungeons & Dragons, and spending time at home to watch Anime and try new recipes.
