For Aaron Walsh and James Pursell, the work of LEAN-STL is personal. As peer support specialists, they work to break down the stigma of talking about addiction and mental health — often sharing their own experience with addiction, recovery and healing in the process. In the two and a half years since LEAN-STL was founded, the pair has connected hundreds of St. Louis laborers and their families with resources. It’s a model they believe will lower the high rates of substance use and suicide among construction workers — one they hope to see adopted by more trade associations in the future.
