Rhinebeck, N.Y.-based Monkfish Book Publishing Company has named a new associate publisher and has added three employees to the company's ownership structure.

Jon M. Sweeney, previously editor at large at Orbis Books, has joined Monkfish as associate publisher, effective May 1. Sweeney has also worked at Ave Maria Press, Paraclete Press, Franciscan Media, SkyLight Paths Publishing, and Jewish Lights Publishing. In his new role, Sweeney will be tasked primarily with growing Monkfish's list.

Additionally, Colin Rolfe has been promoted to director of design, production, and administration, and Anne McGrath has been promoted to literary editor.

Rolfe, McGrath, and Sweeney will join Monkfish publisher Paul Cohen as partners, taking an equity interest in the company. “After twenty years of being a boss with employees," said Cohen in a statement, "it’s exciting working with truly committed partners."

This June marks Monkfish's 21st year in business.
