Pyles & Associates was founded to address the growing needs of adults with intellectual disabilities in southern California to address the scarcity of high-quality behavioral care for these individuals.  While the majority of ABA providers focus on children, we target the specific needs of adults at home, in residential facilities, and day programs.


The company was founded by a doctoral level Board Certified Behavior Analyst (BCBA-D), David A. Pyles, PhD, with extensive experience in the assessment and treatment of severe problem behaviors.  He has published articles in peer-reviewed journals and book chapters detailing the Behavioral Diagnostics approach that he developed with Jon S. Bailey, PhD.  Dr. Pyles has extended that approach to the use of psychotropic medication for people with intellectual disabilities, which has resulted in decreased psychotropic medication use to treat problem behavior, along with reductions in injuries to staff and clients, and in the use of restraint and other restrictive behavioral procedures in a large state-operated developmental center.


Our systems have been developed by practitioners with extensive training and decades of experience providing high quality behavioral services in settings including small group homes, schools, mid-sized (50 to 100 bed) facilities, state operated developmental centers, and entire statewide systems.


We use a behavioral systems analysis approach to providing support for individuals with intellectual disabilities, autism, and those who are dually diagnosed (MI/ID).


Our interlocking systems include:

  • Functional Behavioral Assessments
  • Behavior Support Plans
  • Creating a therapeutic environment
  • Data collection
  • Staff training
  • Ongoing competency assessment
  • Adaptive skills training
  • Quality assurance and improvement


We are a good fit for agencies that:

  • Strive for their clients to have the best quality of life possible
  • Promote independence
  • Provide administrative support
  • Continually support people to live in the least restrictive environments
  • Have clear channels of communication
  • Understand the role of direct support staff, home managers, and administrators
  • Focus on the long-term best interests of the client
  • Seek to provide the best services they can and continuously improve their systems
