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.

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).
