Infinite Spectrum Learning and Behavior, LLC combines the use of different naturalistic ABA models along with Developmentally Appropriate Practice for young learners, ensuring interventions are client centered following guidelines by Dr. Greg Hanley, and Child’s Way ABA. Our goal at Infinite Spectrum is to provide ABA and coordinate and implement Behavior Intervention Plans with Dr. Greg Hanley’s requirement prioritizing safety, televisibility, and rapport.
