Healthcare for the Homeless Program

Greater Portland Health’s 63 Preble Street location, home to our Health Care for the Homeless Program provides primary care and dental services to all clients regardless of their ability to pay. We follow a harm reduction model and provide nonjudgmental, trauma informed care.

We are located in the Bayside Neighborhood of downtown Portland. The Health Care for the Homeless site is located directly across the street from the City’s Preble Street Resource Center and soup kitchen. It is 2 ½ blocks from the shelter hub and 0.7 miles to the south of  Florence House, a shelter for women.


Approximately 40% of GPH’s patients are experiencing homelessness

Greater Portland Health staff often meet patients in their most vulnerable moments: just arriving in a new country, navigating shelter systems, accessing detox/substance use treatment, or spending nights sleeping on the streets. The team builds individual and community capacity by increasing health knowledge and self-sufficiency through a range of activities such as navigation of systems, outreach, community education, informal counseling, social support, and advocacy. This serves to help patients effectively carry out their treatment plans. Team members also serve as cultural brokers between Greater Portland Health, health or social services, and the communities of focus to facilitate access and improve the quality and cultural competence of health care delivery, ensuring positive health outcomes.

Outreach and Community Health Workers (CHWs)

Outreach staff, led by the Director of Social Work, are immersed in and members of Portland's diverse communities, the homeless community, and the recovery community. In coordination with leadership and providers, outreach staff build bridges between GPH and the communities served, facilitating fluid feedback regarding ways to reduce barriers to medical and behavioral health care.

A community health worker (CHW) based at our 63 Preble Street location spends much of her time in the community focusing on ways to bridge the large gap that exists between healthcare services and individuals experiencing homelessness. The CHW spends significant time in the local soup kitchen, resource center, on the street and provides outreach twice a week at the City of Portland Oxford Street Shelter to explain available health services, and support individuals to walk into the health clinic to see a medical provider and/or social worker. CHWs and Social Workers reduce barriers to care by going walking and/or taking the bus with patients to specialist appointments, viewing apartments for rent, going to the pharmacy to get medications, and connecting patients with benefits such as Food Supplemental Program, MaineCare and/or housing vouchers. Peer support provides additional support to those struggling with substance use.  Our peer Support Coordinator meets with patients wherever they are at and supports them through the stages of recovery.

Medication Assisted Recovery Program (MARP)

In response to Maine’s opioid crisis among the homeless population, we rolled out an innovative daily dosing program in 2017.

The program provides daily intensive outpatient support to high-risk patients experiencing homelessness with a focus on those who do not have access to other outpatient or residential treatment.

MARP’s daily observed dosing model has shown clear evidence of positive results in the community. The program optimizes existing substance use disorder (SUD) treatments and recovery-oriented services and adds monitored daily dosing MAT, paired with mental health counseling. Our Preble Street partners provide daily intensive case management, expedite access to entitlements and community services, and support efforts to gain housing and employment.  




Our dental team at 63 Preble Street offers preventative and restorative dental services to all patients regardless of their ability to pay.
