Our Programs

Intensive Day Program
Designed for adolescents and young adults between the ages of 13 and 25 struggling with moderate to severe anxiety or OCD, this outpatient program provides comprehensive, continuous care for expedited and enduring recovery.

Clients in our Intensive Day Program typically have not progressed with weekly therapy on its own. Withdrawal from family, friends, school and favorite activities are common, as well as excessive technology use (social media, gaming) as an unhealthy coping strategy. Our concentrated intensive outpatient program occurs Monday through Friday, over a 6-12 week time frame, depending on severity of symptoms. Each day consists of four hours of targeted individual and group work.

Individual Therapy
Our compassionate clinicians provide individualized therapy sessions to address anxiety and OCD symptoms.

Utilizing proven methods such as Cognitive Behavioral Therapy (CBT), we customize treatment plans supplemented by innovative technologies like bio-feedback, virtual reality, EMDR therapy, and Cognitive Processing therapy as part of a comprehensive treatment strategy.

Parent Coaching Services
Empowering parents to help their anxious child develop resilience, independence, and competence.

Solution-based Coaching Services for parents of children with anxiety. Parents and caregivers will learn to shift their approach from accommodating their child’s anxiety to parenting using constructive strategies and effective support techniques. Parents master skills to break the cycle of accommodation and avoidance, improve family dynamics, and foster a more independent, resilient child. Informed by evidence-based practices of the SPACE* treatment model from The Yale Child Study Center, the program is customized for your family’s specific needs.
