Why choose
Autism Behavior Services, Inc.?

Autism Behavior Services, Inc. was founded in 2010 by Dr. Rosa Patterson, Psy.D, BCBA, LBA, QBA. In creating ABSI, Dr. Patterson’s goal was to help people who are neurodiverse, and make services available to the largest group of people as possible. To that end, Dr. Patterson set about crafting therapy programs that would be unique to every client. It is her goal that ABSI would be a place offering clients and teammates growth, education, and understanding.

To that end, all Behavior Technicians employed by ABSI are certified in CPR, and as an Applied Behavior Analysis Technician (ABAT) or Registered Behavior Technician (RBT), BEFORE they go out into the field to provide services. ABSI’s teammates truly follow a “whole person approach” in the work they do for the company as well as your family. Our mission is that your loved one will become engaged with our therapy programs and technicians, and thus “buy in” to the idea of reaching and exceeding their potential.

Our behavior technicians are certified in CPR as well as ABAT or RBT.
