Expert Program Leaders

Welch Senior Living Memory Care Program Leaders

Welch Senior Living Memory Care leaders are experienced in planning, developing, and managing memory care programs. They are charged with setting the standards for our cutting-edge program, focused on person-centered care. Working in collaboration with executive directors and program directors they establish care protocols, and develop and implement specialized memory care staff training programs. They provide clinical oversight and quality assurance for care planning and resident engagement programs, and are important resources to support the staff, as well as families struggling to cope with a loved one’s diagnosis.

In addition to tapping into trusted medical providers and resources like the local Council on Aging, VNA, Hospice, and Concerto Care, Duxbury House also partners with leading experts across the South Shore.
