Sparking Collaboration | Advancing Treatment
The Profound Autism Summit is a two-day conference that brings together researchers, clinicians, educators, and families to address the needs of people with profound autism across every discipline and every stage of life. It was created in 2023 by Nashoba Learning Group in collaboration with the Profound Autism Alliance.
Profound autism is the population with the highest support needs and the least representation in research, training, and services. Most autism conferences give it a track. We built an entire conference around it, and we bring medicine, behavior analysis, speech, social work, education, research, advocacy, and family experience into the same room rather than keeping them in separate ones.
The 2027 Summit, our fourth, is April 15 to 16 at the Hilton Boston Park Plaza.
Profound autism refers to autistic people who have significant intellectual and communication challenges and require 24/7 support. The Lancet Commission first proposed the term in its December 2021 report, giving families, advocates, and providers a way to describe this group's distinct needs.
A consensus-based research definition for profound autism was introduced at the 2025 INSAR Annual Meeting. That clarity is a first step toward making sure people with profound autism are accurately represented in research rather than excluded from the science that shapes their care. Our thanks to the Profound Autism Alliance and the Autism Science Foundation for supporting that effort.
The Summit was created in 2023 by Nashoba Learning Group in collaboration with the Profound Autism Alliance. One runs the services day to day. The other works on the research and policy that shape them. Bringing both into the same room is the point.

Judith cofounded the Profound Autism Alliance and serves as its president. She trained as a CPA and spent a decade in tax accounting before autism advocacy became her focus in 2005, when her son Jack was diagnosed at age two.
