About Northwell Health Mather Hospital
Northwell Health Mather Hospital provides comprehensive behavioral health services for both adults and adolescents who are dealing with significant psychiatric symptoms. The center offers a partial hospitalization program (PHP), which serves as a structured level of care for individuals who do not require a full inpatient stay but need more support than traditional outpatient therapy. This program is designed to be a step-down from an inpatient unit or to help prevent the need for hospitalization altogether. They offer a safe and therapeutic environment for individuals to focus on their mental health and recovery during the day while returning home in the evenings.
The treatment at the center is built around a collaborative and individualized plan, created with input from the client, their family, and their referring doctor. A variety of therapeutic methods are used, including individual, group, and family therapy sessions. Through these therapies, clients work on developing better coping strategies to handle daily stressors, learn to effectively manage their psychiatric symptoms, and gain a deeper understanding of their mental and emotional health. The goal is to empower each person with the skills needed for independent functioning and long-term wellness in a supportive setting.
A distinctive aspect of the program is its structured, full-day schedule, which runs from Monday through Friday, providing consistency and intensive care. For adolescents, the program integrates educational services, including tutoring, to ensure they can keep up with their schoolwork while receiving treatment. Furthermore, professional staff are available for crisis coverage 24 hours a day, 7 days a week, ensuring that support is always accessible for clients and their families when it is needed most, providing a crucial safety net.
