Private, Concierge Behavior Analytic Services
Across Long Island’s East End
Some of Our Services
Concierge BCBA
This model is ideal for families seeking a true clinical partner. We provide in-home visits, rapid assessments (FBAs, BIPs), hands-on caregiver coaching, and IEP support. You will have a consistent clinician who understands your history and goals, offering direct access between sessions to ensure you are supported whenever needs arise.
ABA Program Development & Oversight
We develop individualized treatment plans by assessing unique needs, setting measurable goals, and creating evidence-based procedures. We design custom materials for parents and staff to implement with success.
Parent & Staff Training
We offer specialized workshops and private sessions designed to empower caregivers and household staff with practical behavior management strategies.
BCBA, BCaBA & RBT Supervision
We provide high-quality clinical supervision and mentorship tailored to meet BACB requirements for aspiring BCBAs, BCaBAs, and practicing Registered Behavior Technicians.
District Support
We offer independent consultation for schools, working with administrators and teachers to build educational supports. Services include behavior assessments, IEP development, and professional training to foster inclusive, thriving classroom environments for all students and staff.
Functional Behavior Assessments (FBA)
Detailed evaluations designed to identify the underlying causes of challenging behaviors and create effective, data-driven intervention plans for home and school.
Behavior Intervention Plans (BIP)
Following an FBA, we create strategies that address the root cause of a behavior rather than just the symptoms. These plans provide clear goals and consistent guidance for caregivers and educators, ensuring that interventions lead to meaningful, lasting change across all settings.
Intensive Toilet Training
Toileting independence is a vital milestone that brings privacy and confidence. At East End ABA, we provide evidence-based, dignity-preserving programs tailored to each individual’s needs. We help children, teens, and adults reach this goal with a supportive approach that opens doors to new opportunities at home and in the community.
AAC Consultation
We provide Augmentative and Alternative Communication (AAC) support for individuals whose speech does not fully meet their needs. From picture boards to devices like TouchChat, we serve those with developmental disabilities or following medical changes; such as stroke or brain injury. We collaborate with speech-language pathologists at the Community Speech Language and Learning Center to ensure every voice is heard through a respectful, consistent plan.
Sleep Support
We evaluate sleep routines and sensory needs to build calm, predictable bedtime environments. Using gentle, gradual strategies that respect personal comfort, we focus on sustainable regulation for the whole household. Better sleep leads to better days, improving the quality of life for the individuals we serve and the families who love them.
