Ellenhorn A Community Treatment (PACT) team providing comprehensive, individualized and multidisciplinary psychiatric and psychosocial services

Ellenhorn is an effective alternative to long-term residential care, delivering intensive and individualized multidisciplinary services. We have three locations: Boston, Los Angeles, and New York City. For clients who are local to Boston or initially need more structure, we offer our innovative residential setting. As an evidence-based Program for Assertive Community Team (PACT), we have a high success rate with difficult cases that present co-occurring medical, substance misuse or complex psychiatric issues, and with clients who don’t fit into traditional residential programs. Our treatment approach combines psychosocial rehabilitation, medical/psychiatric care, and a focus on physical wellness. From day one, we work toward the client’s reintegration into the community, re-engagement with life, and rediscovery of a sense of purpose and hope. We believe that staying connected to the world is central to an individual getting better. Aside from psychosocial support, robust psychiatric care, vocational counseling, nursing, and non-pharmacological therapies, we provide direct support for our clients in regards to activities of daily living. As a PACT program, Ellenhorn is a “single source” model of treatment. Instead of providing only one component of a person’s treatment and referring-out for other services, we offer a full range of rehabilitation and treatment resources delivered by a multidisciplinary team. In this integrated approach to services, the “whole person,” rather than a cluster of symptoms is treated. SUPPORT INCLUDES:
Psychiatry/Psychopharmacology
Open Dialogue for Psychosis
Mentalized Based Therapy (MBT)
Wellness Coaching
Social Rhythms Therapy
Integrated Dual Diagnosis Treatment (IDDT) for Substance Use
Community Integration
Psychosocial Rehabilitation
Medication Independence Planning
Transportation to clinical and community appts
Home and Community Based Services
Side-by-side cleaning
Independence planning

Every clinical team has cases that test them. Clients who struggle to trust help, or whose complexity creates strain not just in the room, but across the whole team. AMBIT (Adaptive Mentalization-Based Integrative Treatment) was built for just such cases.

Join Ellenhorn Director of AMBIT Shelly Simpson, LCSW for an AMBIT workshop and consultation series. The series will feature academic lectures and skill-building activities, and attendees will leave with AMBIT techniques they can immediately put into practice.
