Holly O’Donnell – CEO

Bush for “Outstanding Service-Learning Opportunities,” the Washington Business Journal for “Exceptional Involvement of Corporate Volunteers,” Meyer Foundation for “Innovative Fundraising by an Executive Director,” and the DC Public Schools and Washington Regional Association of Grantmakers as a “Community Based Organization Partner of the Year.” Previous to DC SCORES, she was a Presidential Appointee to the Department of Education’s White House America Reads Challenge under President Clinton.

Holly’s commitment to the mission of the Bazelon Center is deeply personal.  Her lifelong advocacy for people with disabilities is inspired by her brother Brendan who has an intellectual disability. Her parents worked tirelessly and creatively to give him the same opportunities as Holly and other children. As often as possible, Brendan was taught in the same setting as his non-disabled peers.  He received a high school diploma, served in AmeriCorps, and completed coursework at Bunker Hill Community College. Following the early deaths of their parents, Holly and Brendan became a co-dependent sibling team supporting each other.  Brendan lives an independent, fulfilling, and fun life in Boston, his favorite city.  On March 23, 1999, then-Senator John Kerry delivered a speech on the Senate Floor that Brendan wrote describing what it’s like to have a learning disability.  Download Storm in My Mind (PDF).
