Casa Rubén Foundation is a nonprofit organization serving community health needs, with a focus on improving the health and wellbeing of underserved people, especially those who are uninsured or underinsured. Its work aims to reduce health disparities through preventive care, clinical services, and community outreach. The foundation has served the community since 2015 and describes its strategic direction as guiding its work for almost 30 years.

Its clinic specializes in pediatrics and family medicine, offering primary care and support for patients and families. Services include a patient portal where patients can request appointments, as well as a mobile health clinic initiative intended to expand access to primary care and vaccinations for children across Montgomery County, including those who are uninsured, underinsured, or under-resourced. Casa Rubén also organizes pop-up clinics and vaccination events, including COVID-19 vaccination clinics, and shares health information with the community.

Based in Silver Spring, Maryland, the foundation works with community partners to advance accessible care and connect residents with health services
