Mindy Grossman is leaving HSN Inc. on May 24 2017 and assuming the role of president and CEO of Weight Watchers in July. Grossman replaces James Chambers at the weight-loss program operator. Chambers stepped down in September 2016 amid the company’s struggles to build on the momentum it garnered from an alliance with Oprah Winfrey. Weight Watchers says that until Grossman’s arrival it will continue to be led by the members of the interim office of the CEO.
