DK is reorganizing its North American leadership structure, according to a letter from Mary Marotta, senior v-p, to staff today.

Carol Stokke has been promoted to v-p of sales, reporting directly to Marotta, in which position she will oversee overall day-to-day leadership of the U.S. sales team. Stokke will be hiring a new manager to oversee relations with Penguin Random House’s field groups. (DK is a division of PRH).

Reporting to Stokke are Tim Greco, v-p of mass digital; Savannah D’Amico, educational sales manager for Ingram and Baker Taylor; Meg Miguelino, national accounts manager for Barnes Noble and Books-a-Million; Jay Franco, who has been newly appointed director of special sales; and sales manager Jennifer Stephen.

In addition to the changes in the sales team, Meghan Marton has been promoted to director of custom publishing, still reporting to Marotta. Billy Fields has been named director of publishing operations, also reporting to Marotta, in which role he will work, in part, with the publishing team in the U.K. Katy Miller has been named metadata coordinator, and will report to Fields, as will executive editor of Americanization Lori Hand; managing editor Jill Thomas; and associate managing editor Jennifer Chung.

While Marotta has yet to appoint a v-p of marketing and publicity, that appointment, she wrote, is imminent, and she intends to expand the marketing team by adding specialists in travel, education, digital, and brand, all of whom will report to Jaimie Cona, senior director of marketing. Also on the marketing side, Kristen Pozzuoli has been named senior marketing manager for education and library, and Laura Hernandez has been promoted to marketing coordinator.

As a result of these changes, Marotta wrote, interactive media director Rob Roglev will leave the publisher. All changes are effective immediately.
