The CEO and co-founder of Chicago-based primary care provider VillageMD has resigned, a move that comes as Walgreens Boots Alliance considers selling its stake in the business. VillageMD spokesperson Molly Lynch confirmed Wednesday that Tim Barry has stepped down as CEO and board chair and that the company’s board has appointed VillageMD Chief Operating Officer Jim Murray to serve as interim CEO “effective immediately.” Lynch did not answer questions about why Barry departed. Deerfield-based Walgreens said in a statement: “We look forward to continuing to partner with Jim Murray as he assumes day-to-day leadership responsibilities.” Murray has been “integral in helping lead the company’s turnaround as VillageMD makes meaningful progress and positions itself for profitable growth,” Walgreens added.
