Program on Immigrant Families and Unhoused Communities

About the program

The FXB’s Program for Immigrant Families and Unhoused Communities is a joint program with the Harvard T.H. Chan School of Public Health. It is a unique place for scholar-practitioners who are both in the classroom and working directly with affected communities. The program highlights the need for greater public health involvement and a human rights-based focus on the health of people marginalized by economic impoverishment, displacement, xenophobia and racism in the United States. Migration and homelessness, structural determinants of health which increasingly overlap, broadly impact the health of families, child development, and community wellbeing. Increased criminalization of both groups negatively impacts access to health-promoting services and long-term health outcomes.

This work includes a new Partnership for Community Mental Health and Immigrant Wellbeing, co-led by Dr. Maggie Sullivan and Dr. Jocelyn Chu. The Partnership aims to better understand the local landscape of community mental health supports for immigrants, grow academic-community collaborations to support immigrant mental health, and create mutually beneficial learning opportunities for public health students and immigrant-serving organizations.

The Program includes a course on health and homelessness, one of the few such graduate-level public health courses, co-taught by Dr. Sullivan and Dr. Jill Roncarati; collaborative research in immigrant health; and student mentorship.

The FXB Center for Health and Human Rights Program on Immigrant Families and Unhoused Communities is led by Dr. Margaret Sullivan, FNP-BC, DrPH, FAAN, a Distinguished Fellow of the National Academies of Practice (NAP) in Nursing, and a Fellow of the American Academy of Nursing (FAAN). Trained as a family nurse practitioner, Dr. Sullivan brings two decades of experience serving immigrants and unhoused populations in primary care settings. She also co-advises the Harvard Students Human Rights Collaborative and conducts forensic medical evaluations for asylum with Harvard Medical School’s Asylum Clinic.

APHA 2025

Dr. Margaret (Maggie) Sullivan, FNP-BC, DrPH, FAAN, presented at the 2025 APHA Annual Meeting in Washington, D.C. The session was titled “The Role of Community Engagement and Multidisciplinary Initiatives in Advancing Health of Immigrants, Refugees, and Forcibly Displaced Populations.” It covered the conditions that have led to a decrease in health-seeking behaviors and increase in mental health symptoms in immigrant communities. The negative impact of those unmet needs on adults, children and families has broad implications for maternal child health, nutrition, completion of routine screenings and vaccinations, educational attainment, self-efficacy, economic stability, and family cohesion.

Numerous barriers persist including stigma, disproportionately low numbers of bilingual/bicultural behavioral health providers, long wait times, limited insurance eligibility, and competing priorities (i.e. employment, housing, legal matters).

The session explored how new models for psychosocial interventions at the community level are needed to increase access, language concordance, culturally sensitive approaches, and targeted referrals to higher levels of care. Such models of care might varyingly incorporate language-based support groups, non-clinical and culturally relevant healing techniques (i.e. music and art), peer counseling, and participant eligibility regardless of primary care affiliation or not having a known behavioral health diagnosis. These examples prioritize skill-building, social cohesion, psychosocial wellness and accessibility outside of the traditional medical system.
