The Gannett Co. announced Thursday that Janet Hasson, president and publisher of The Journal News Media Group, is resigning effective March 6.

Michael G. Kane, east group president for Gannett U.S. Community Publishing, said Hasson will leave the White Plains-based media property to pursue another opportunity.

George Troyano, vice president sales/advertising for The Journal News Media Group, will serve as interim publisher.

Kane made the announcement to the staff in a conference call, which he opened by thanking Hasson for her four years of service. “What we want to do with a new publisher, obviously, is transition through and carry a lot of the same strategies that you’re working on now, executing them well in the field and serving our readers and customers well,” he said.

Hasson, 55, of Greenwich, Conn., arrived at The Journal News in June 2011 during the news organization’s digital transition. She oversaw the publication’s move from its former printing plant in West Harrison to 1133 Westchester Ave. in White Plains, and the roll-out of new digital and print products.

“I walk out of this place really proud of the team that’s in here and I know you’re going to keep doing really great and we’ve got a great plan in place,” Hasson told her staff.

Hasson pointed out her leadership of the company’s transition from a print-centric to a digital news organization as her biggest accomplishment.

“I really feel we’re meeting the new needs of our readers and our advertisers,” said Hasson.

Besides her work at The Journal News, Hasson serves on the boards of the Westchester County Association and ArtsWestchester. She said her successor will likely continue her public work.

“Community involvement is a very important role for the publisher and that will be a decision for the next publisher. I’m sure it will be important. That’s just part of the role of the publisher,” Hasson said.
