It is with deep sadness, and profound gratitude, that we share the passing of Dave Gustafson, PhD.
Dave believed something simple and radical: no one should suffer twice. Not from their illness, and not from the broken systems meant to help them heal.
From that conviction, Dave saw technology not as a replacement for human connection, but as a bridge to it. He understood that recovery doesn't happen only in a clinic or a counselor's office. It happens on day 1 in treatment or day 400 in recovery. It can happen in the middle of a workday or at 2am. The need for ongoing support and community continues throughout someone's life.
As founder of the University of Wisconsin-Madison Center for Health Enhancement Systems Studies (CHESS), he dedicated his career to closing that gap. His work included developing and proving the evidence of the A-CHESS app, which he then commercialized as co-founder of CHESS Health as the Connections App that today is used by thousands of people living with substance use disorder. Integrated as part of their treatment plan, Connections provides recovery engagement and support for individuals through sustained connection to their provider, peers, and an online community of support - meeting people where they are and keeping them engaged in their recovery.
We are grateful for his tireless vision, his humanity, and his belief that the right technology, in the right hands, can change and save lives.
In Dave's name, we are honored to carry that mission forward đź’™
