Our Chapter Board

The Chapter Board is comprised of approximately twenty volunteers with diverse backgrounds who meet monthly to direct the operation of the APDA Massachusetts Chapter. Board members are not paid for their services and are committed to the mission of helping find a cure through funding research, and to helping people in their day-to-day activities. Board members work extremely hard in planning and organizing information sessions, the annual Optimism Walk and numerous fundraising events.

Working closely with the APDA Information & Referral Center at Boston University School of Medicine and Massachusetts’s two APDA Centers for Advanced Research, the APDA Massachusetts Chapter strives to provide service to the approximately 21,000 people living with Parkinson’s in the state,* as well as their family members and care partners. The Chapter fulfills this mission by giving grants to organizations providing Parkinson’s programming,  supplying guidance and education to support groups across the state, and supporting educational programming in collaboration with the APDA Information & Referral Center at Boston University School of Medicine, among other activities.
