Don Anderson passed away March 3, 2023. Don taught for the school of social work for many years, teaching and mentoring students in the intellectual and developmental disabilities area. Among his many initiatives, at the UW-Madison’s Waisman Center, he was responsible for launching the TIES program. TIES is nationally known for providing behavioral support for persons with intellectual and developmental disabilities who have challenging behaviors so they can more fully participate in community life. He also started numerous community agencies that provide supported living, supported employment and crisis response services. Most importantly, he mentored and nurtured dozens of students who have become leaders on a local, state, and national level. After retirement from UW-Madison, Don continued to advocate for full community integration, support for families, and the closing of institutions and segregated programs.
