Crown Media Family Networks’ lead programming and production executive Michelle Vicary is departing her post as executive vice president at the start of June, the company said Monday. Randy Pope, the company’s senior vice president of programming and development, and Darren Melameth, senior vice president of programming and content strategy, will serve as interim co-leads while the company looks for a successor.

“We thank Michelle for her contributions to the growth and success of our networks and for helping to bring the quintessential Hallmark brand to life,” said Wonya Lucas, the president and chief executive officer of Crown Media Family Networks, in a statement. “We appreciate the passion and effort she has brought to our team and to the company.”

Vicary had held posts at various Crown Media properties during her time there, boosting the prominence of networks including Hallmark Channel, Hallmark Movies & Mysteries, and Hallmark Drama, during which time original series and movies such as “When Calls the Heart,” “Good Witch” and the long-running “Home & Family” were released.

Separately, Crown Media Family Networks in early May named former TV One programming and production exec Toni Judkins as senior vice president of programming and development for Hallmark Channel and Hallmark Movies & Mysteries, and elevated Hallmark content exec Jessica Callahan to vice president of programming and development; both were then slated to report to Vicary. Last July, Lucas was named Crown Media Family Networks’ president and CEO after a tenure as head of Public Broadcasting Atlanta, overseeing its NPR and PBS outlets.
