Our Mission

Local solutions for every community.

The Arlene and Michael Rosen Foundation invests in local solutions that address the needs of community’s most vulnerable populations, with an emphasis on those impacted by homelessness, addiction, and mental illness.

Who We Are


We are an active, engaged philanthropic partner who provides technical assistance, coalition-building, and financial support to communities interested in new solutions to homelessness, addiction, and mental illness.

We seek to pioneer changes to current systems of care and risk reduction for people experiencing homelessness, addiction, and/or mental illness to improve overall individual and community wellness. We also seek to reduce and eliminate community focus on institutionalized care, particularly emergency departments and incarceration.
