Hazelden Betty Ford Foundation CEO Mark Mishek has announced he will retire next year. 

Created as a result of a merger between Hazelden Foundation and Betty Ford Center, the organization dubs itself as the largest nonprofit substance use disorder (SUD) treatment provider in the country. It has 17 locations nationwide, offering both inpatient and outpatient treatment for adolescents and adults. The foundation also has a graduate school of addiction studies, a publishing division, an advocacy arm and an addiction research center, among other programs and initiatives. 

Mischek’s leadership predates the combined company itself. He was hired as CEO of Center City, Minnesota-based Hazelden back in 2008. 

The company’s 2014 merger with Rancho Mirage, California-based Betty Ford occurred during his tenure. On top of that, he oversaw a number of other acquisition and organic growth pursuits during his time with the company.

When Mischek stepped into the CEO role, Hazelden had six locations nationwide. Today, his nonprofit has just shy of three times that number, and “is on its way to offering virtual care in all 50 states through its industry-leading RecoveryGo behavioral health service,” according to a press release announcing the news. 

Mischek says he will step down when his successor is hired, likely in the first half of 2021.
