Hallmark Health wants to send the very best -- health care, that is -- to residents living in the suburbs north of Boston. The system includes the Lawrence Memorial and Melrose-Wakefield hospitals, which together have about 370 beds. The hospitals provide a full range of health services including primary, diagnostic, surgical, and rehabilitative care. The Hallmark network also includes the Malden Medical Center (radiology, laboratory, and dialysis services), family health clinics, physician offices, long-term health care facilities, and home health services. Physicians-in-training are supported through a family practice residency program offered in association with Tufts University.
