Sharewood is a free health education program that also provides limited health care services to the medically underserved populations of the Malden and Greater Boston areas. Medical services are managed by volunteer physicians and faculty from Tufts University under the direction Gregory Sawin, M.D., Medical Director/Advisor. Dr. Sawin is also Assistant Professor of Family Medicine at Tufts University School of Medicine and Program Director of the Tufts Family Medicine Residency at Cambridge Health Alliance. The administrative responsibility for Sharewood is held by a board of 27 volunteer medical students from Tufts University School of Medicine. Dental students and faculty volunteers from Tufts University School of Dental Medicine also contribute, as do physician assistant, nutrition, public health, and undergraduate students from Tufts University.

The name "Sharewood" is based on the Robin Hood/Sherwood Forest idea of giving to the poor. The reason "Sherwood" became "Sharewood" is that the Sharewood Project is not about robbery and simple handouts. It is a mutual give and take where those receiving health services provide a learning opportunity for the students of Tufts University School of Medicine. The experience is shared rather than given.
