Meet Michael Green
Michael Green began his way up the publishing ladder as an editorial assistant for a boutique children’s book imprint called Philomel. He would go on to spend the next 27 years with Philomel, climbing to the roles of President and Publisher while redefining the imprint as a commercial force and a cornerstone for Penguin Young Readers group (Penguin Random House). As an editor, he acquired and helped develop 30 New York Times bestselling titles, including several that went all the way to #1. As head of Philomel, Michael also oversaw the release of multiple award-winning and international bestsellers, working hand in hand with some of the sharpest marketing, publicity, sales, foreign rights, and production teams in the business, broadening his experience with every aspect of a book’s journey to publication and beyond.
Michael is currently the acquisitions editor for the indie children's book publisher Marble Press (www.MarblePress.com), where he is building a brand-new list comprised of picture books, middle grade fiction, and graphic novels. He is married to an audiobook producer/director for Hachette Book Group and is a father to one son. He is a diehard fan of the New York Mets and New York Giants, SEC college football, slow-burn TV dramas, pitch-dark comedies, classic rock, and strawberry Twizzlers by the handful. Make him belly-laugh and you’ll have a friend for life.
Meet Kaitlin Severini
Kaitlin Severini began her career as a copy editor by teaching Spanish at a high school in New Jersey . . . where she used her free periods to apply for copyediting jobs in children’s book publishing. In 2010 she started as a production editor (Production editoris: little-known publishing species responsible for keeping other departments on track to ensure on-time, error-free publication) for Henry Holt and Square Fish imprints (within the Macmillan Children’s Publishing Group). She then moved over to work with two of Simon & Schuster’s children’s imprints, Atheneum and Margaret K. McElderry. Kaitlin has worked on books by revolutionary authors like Phyllis Reynolds Naylor and Laurie Halse Anderson, and was the production editor for the Caldecott Medal–winning and Sibert Honor picture book Locomotive. In 2013, she left her desk job to travel while freelancing full-time, and once mailed a marked-up manuscript all the way from Koh Phangan, Thailand, to New York City (and yes, it arrived safe and sound!).
Since she began freelancing, Kaitlin has worked on nearly 1,000 books, from novelty and picture books for young children (which she now tests out on her own young son), to chapter books and young adult novels. . . . Occasionally some grown-up books sneak in too.
