Therapy Staff:
An intensive in-home therapy team consists of several different staff members.  The Lead Therapist (BTLS), a Behavioral Treatment Therapist and 3-4 Behavioral Treatment Technicians will typically compose the therapy team.

The Lead Therapist and Associate Director oversee the clinic.  At times, the Associate Director and/or other BCBAs may provide additional home or office visits when necessary in addition to meeting regularly with BTLS and Behavioral Treatment Therapists to help oversee the treatment of care. 

A Behavioral Treatment Therapist (BT Therapist) is an individual who possesses either a Master's Degree with at least 400 hours of direct ABA experience or a Bachelor's degree with at least 2000 hours of direct ABA experience.  In addition, WNCA BT Therapists must complete a mentoring process that equips them for managing a case.  

A Behavioral Treatment Technician (BT Tech) is the direct treatment provider within the therapy team. This critical team member directly implements the programs to teach skills to the child with Autism. Technician qualifications are that the person must be at least 18 years old, have a high school diploma (or equivalent), pass a caregiver and criminal background check, have 40 hours of supervised training and love children!
