Alex Truesdell received a B.S. (1979) and M.Ed. (1998) from Lesley University and an M.Ed. (1982) from Boston College. She was affiliated (1981–1998) with the Perkins School for the Blind, where she was founder and coordinator of the Assistive Device Center, prior to founding Adaptive Design Association, Inc., in 2001. Alex Truesdell is a visionary social entrepreneur who creates low-tech, affordable tools and furniture that enable children with disabilities to participate actively in their homes, schools, and communities. Truesdell challenges our assumption that disabilities are fixed and instead suggests that limitations can be minimized, or even eliminated, with effective user-inspired adaptations—the kind she creates as founder and director of the nonprofit Adaptive Design Association (ADA).
