Comprehensive Evaluations
Our neuropsychological evaluations use gold-standard tools to measure cognitive functioning, learning styles, and emotional development. We identify learning disabilities, giftedness, and developmental delays through multi-specialist assessments that inform targeted treatment plans. The process includes school collaboration and follow-up recommendations.
Short-term Therapy
We offer focused therapy sessions addressing specific concerns like anxiety management, behavioral regulation, and coping skill development. Our evidence-based interventions help children navigate life stressors and improve communication abilities through structured, goal-oriented sessions lasting several weeks.
Long-term Therapy
For complex needs requiring sustained care, we provide extended therapy addressing chronic conditions, emotional disorders, and developmental challenges. Our psychologists work with families to implement lasting strategies for managing chronic illness, improving social skills, and enhancing overall well-being over multiple months.
Special Education Advocacy
We assist families with IEPs, 504 plans, and special education legal processes. Our team interprets evaluation data for school teams, recommends evidence-based accommodations, and participates in mediation to ensure appropriate educational support aligned with diagnostic findings.
Family Case Management
We help families navigate healthcare and education systems by coordinating care between pediatricians, therapists, and school staff. Services include treatment plan implementation support, insurance guidance, and connecting families with community resources for comprehensive care.
