Celebrating the Legacy of Leo Sarkissian


Leo’s lifelong career has been dedicated to ensuring that people with intellectual and developmental disabilities, including autism, have the right and the opportunities to live full lives in the community. Leo has impacted countless individuals and families across this state both directly and through his state and national advocacy and policy work. It is not an overstatement to say that Leo will affect people for decades to come. He has been recognized numerous times for his achievements by state and national organizations, including The Arc’s National Conference of Executives Executive Excellence Award in 2022.

This is his enormous and lasting legacy.

Join us in the coming months as we recognize and celebrate Leo’s dedication, commitment, and effectiveness and thank him for all he has done.
