Bold Idea 

Increase access to health and improve healthy behaviors by providing free culturally and linguistically appropriate health services to our clients in the community.


Designed in collaboration with community partners over twenty years ago, the Family Van is a mobile clinic that increases access to health care and improves the health status of residents in Boston’s most underserved communities. The Family Van's charter is to empower community members through improved health literacy and preventive screenings to live healthier lives, while establishing an environment of encouragement and confidence. Our team is comprised of a diversity of members, from health educators to HIV counselors, registered dieticians to volunteers, as well as other health professionals and partners. The Family Van was co-founded by Nancy E. Oriol, Cheryl L. Dorsey, Tamara Callahan, and Ramona Hamblin.


Tamara L. Callahan, M.D. is an Associate Professor of Clinical Obstetrics and Gynecology at Vanderbilt University School of Medicine.
