Hector Ruiz
Founder / Director
Hector has been in the field of Applied Behavior Analysis (ABA) since 2001, when he began working as an in-home therapist in El Paso. Hector graduated with a Bachelors in Psychology from the University of Texas at El Paso (UTEP) in 2002 and a Master’s of Science in ABA from Northeastern University in Boston Massachusetts in 2006.

Prior to founding ABA Comprehensive Services, Hector garnered extensive experience as the Clinical Manager for a school district-based ABA program for 7 and 1⁄2 years, overseeing a program that served over 150 children with autism daily.
Hector’s commitment to the field dates back to growing up with his younger brother with autism. His family moved to the states in 1990 in need of adequate services that were not available in his native Puerto Rico. This continues to be a driving force in Hector’s commitment to providing exceptional services to families facing similar challenges in under-served communities.
His interests within the field include:
- The integration of applied behavior analytic services within the school setting, particularly as it relates to collaborating with other professionals to maximize student outcomes.
- The dissemination of behavior analysis within Spanish speaking communities. Hector has provided seminars and workshops in Spanish and collaborated with Dr. Mark Sundberg in the translation of the VB-MAPP app, as well as with ABA España in the translation of 2nd and 3rd Edition of “Applied Behavior Analysis” by Cooper, Heron, Heward (2007).
- Language-based (Verbal Behavior) assessment and interventions, in particular in their effectiveness towards reducing problem behavior.

Esmeralda Resendez
Lead Registered Behavior Technician, Student Analyst
Esmie has been in the field of ABA since 2017, when she became an RBT in El Paso, TX, at 18 years old. Over the years, she has gained experience in clinic and in-home settings and has worked with children and adults ranging from 2 to 44 years old.
Working with the ASD community had been a goal of Esmie’s from a very young age after her nephew got diagnosed with autism. She saw the positive change that her nephew’s therapists made throughout his early childhood, which confirmed that someday, she would want to give back to the community by continuing that chain. Throughout her early years as an RBT, Esmie then realized that there was a concerning need for ethical ABA services in El Paso that were trauma-free, child-centered, and promoted a strengths-based approach rather than compliance-based interventions. She also noticed that there was a need for ABA services in Spanish to support the ASD community and their families along the border. This has driven her to pursue her BCBA certification.
Esmie received her Bachelor of Arts in Psychology with a minor in Spanish from the University of Texas at El Paso in 2020. She then received her Master of Arts in Special Education with a concentration in Applied Behavior Analysis from Arizona State University in 2023. As a student analyst, Esmie is very close to completing her fieldwork hours and hopes to be eligible to test for her BCBA certification by the end of 2024.
Julie Smith
Care Coordinator
Julie has been working with special needs children since 2018, when she volunteered at a summer camp for children on the autism spectrum and then took a job as a swim instructor for children with Down syndrome. Julie loved working in these settings but felt limited in the individual impact she could make on the children in a group setting. She felt called to do something where she could work 1:1 with children on the autism spectrum, and soon after, she discovered the field of ABA.
Julie transitioned into the field of ABA in 2021 when she became an RBT and started working in Las Cruces, NM. In early 2022, Julie moved to El Paso and began working as an RBT and Care Coordinator for ABA Comprehensive. As an RBT, Julie worked with children ages 3 to 13. After taking a break in 2023 for a program abroad, Julie returned to ABA Comprehensive to work as a Care Coordinator while she pursued her Master’s degree in Couples, Marriage, and Family Therapy.
Throughout her work in the field of ABA, Julie noticed how many stressors families go through navigating supporting their children’s autism and how many mental health needs individuals with autism have themselves. After graduating from her Master’s program, Julie wants to specialize in providing therapy to individuals with autism and their families to support them with these stressors. Julie is also working on a master’s thesis on autism in adult women and hopes to contribute to helping the field better understand the nuances of autism presentation in girls and women.
