As with many underserved populations, migrants, immigrants, and asylum seekers encounter barriers to access culturally responsive high-quality health care in the United States. Clinicians dedicated to serving them struggle to reach them, and lack strategies, resources, and technical assistance to remove barriers to care. Migrant Clinicians Network advocates for these populations’ health needs, develops both patient-facing and clinical resources, and provides services and technical assistance to support clinical care on the frontlines. Migrant Clinicians Network’s goal is to create practical solutions at the intersection of vulnerability, migration, and health. In this article, the authors examine the underserved populations in the United States that Migrant Clinicians Network seeks to serve, and the efforts built to meet their basic health needs.
