Our History

Adaptive Design Association (ADA) was established as an independent non-profit in 2001.  Based in Manhattan, New York, ADA has been transforming the lives of disabled individuals by inventing and producing innovative, low-cost adaptive design solutions for over twenty years.


Alex Truesdell, Founder, and  Director Emeritus, began creating adaptive solutions at Perkins School for the Blind when she was a teacher for children with multiple disabilities.  Alex invented and produced adaptive tools by using affordable materials such as cardboard and rolled towels.  Through years of practice, Alex transformed ideas and frustrations into highly customized and successful solutions.  In 2015 The MacArthur Foundation recognized ADA's innovative approach to solving critical global problems by awarding Alex with a MacArthur Fellowship.


Today, under the leadership of Executive Director Jennifer Hercman, Adaptive Design Association has grown its programmatic scope to strengthen adaptive solutions for individuals with physical disabilities, producing three-dimensional communication learning cards for the visually impaired, and launching an innovative work program for students with Autism in the New York Public School system.

About the Founder

Untitled_Artwork 28_edited.png

In 1981, Alex Truesdell, met two people that forever inspired her to better the lives of others.

Alex Truesdell


In that year, Alex Truesdell, an early childhood teacher at the Perkins School for the Blind in Boston, met Erin, an infant with severe multiple disabilities. A few months later, Alex’s aunt lost the use of her fingers and thumbs following a spinal cord injury. “I had never heard of adaptive technology, but suddenly found myself waking up in the night thinking of adaptations. I rolled towels into bolsters, carved notches in toys, and threaded straps through seat backs.” With the help of her Uncle Frank, a skilled builder, Alex learned to work with all kinds of materials, and together, they transformed ideas and frustrations into highly customized solutions for Erin and her Aunt Lynn.

Over the next few years, Alex set up a small workshop in her basement and made many more adaptations for children on her caseload. Alex was eventually hired full-time by the Perkins School to start the Assistive Device Center. In 1998, Alex relocated to New York City with the goal of replicating the practice and philosophy of adaptive design, and adding an internship program for women re-entering the workforce through Alternatives To Incarceration. Through a great stroke of luck, Alex met Antoinette LaSorsa and they developed a pilot called “Creative Constructions.” In 2001 they established the Adaptive Design Association as an independent nonprofit.  In 2015 The MacArthur Foundation recognized Alex's innovative approach to solving a critical global problem and awarded her the MacArthur Fellowship.
