Our Services

Mental Health & Therapy

Our clinicians provide individual therapy, couples counseling, trauma work, family therapy, and services for children and teens. Many of our team members specialize in working with neurodivergent clients, trauma, and relational growth.

Psychological & Developmental Assessments

We offer a full suite of evaluations, including autism diagnostic assessments (child and adult), developmental evaluations, re-evaluations, psychoeducational testing, and Independent Educational Evaluations (IEEs). These assessments help with diagnostic clarity, academic planning, and treatment planning.

RDI® / Developmental Therapy for Autism

Our developmental therapists provide RDI® therapy — a relationship-based model designed to build connection, dynamic thinking, and flexibility in autistic individuals. We work closely with families in the home, clinic, and community settings, supporting long-term social emotional development with a client-centered approach.
