Board Certified Behavior Analysts

At Elite ABA Services, our Board Certified Behavior Analysts (BCBA's) provide a level of support unmatched in the community. Our BCBA's carry small case loads, generally 6 clients or less per Clinician. The Behavior Analysis Certification Board recommends caseloads of 10-15 clients per BCBA, which often gets exceeded in community practice. Carrying such a small caseload allows our BCBA's to provide a focused level of support to all the families we serve.
