Ben Cort

Ben Cort’s passion for recovery, prevention and harm reduction comes from his own struggle with substance abuse. Sober since June 15, 1996, Ben has been a part of the recovery community in almost every way imaginable. From recipient to provider to spokesperson, Ben has a deep understanding of the issues and a personal motivation to see the harmful effects of drug and alcohol abuse minimized.

Today, he serves as director of professional relations for an adult substance-addiction treatment hospital. However, Ben built much of his career outside of the field of substance abuse recovery. Until 2007, he was the director of human resources at an S&P 500 firm. But his departure from that role did, indeed, compel him to do do more to help people enduring the substance struggles he knows so well. Ben started out by working to support a Colorado-based nonprofit that helps people regain sobriety, Phoenix Multisport (PM). As an original board member and then the nonprofit’s first full-time employee, he was instrumental in building Phoenix Multisport into a nationally recognized organization lauded for its innovative approach to building sober communities around sport and healthy activities. He worked extensively with the treatment community and with drug courts and the therapy community as advisor, a member of clinical teams, frequent speaker and liaison.

As someone who understands the experience of addiction treatment as much as the leadership of the programs delivering that treatment, Ben brings a holistic, compassionate and informed perspective to SAM’s efforts.
