Board of Directors

Dena Cohen is a writer and editor whose main focus has been psychiatry, mental health, and the book publishing industry. She was an Assistant Editor as well as a freelance writer and book reviewer for Publishers Weekly. Her career shifted into medical publishing, where she was Senior Editor of Primary Psychiatry, a psychiatry journal aimed at primary care physicians and psychiatrists, after which she freelanced as a copy editor for numerous healthcare advertising and medical education companies. In 2012, Dena started an online forum for Jews with mood disorders—the first steps in what culminated in founding Refa’enu. Refa’enu was granted non-profit status in New Jersey in January 2014, and Federal non-profit status as a 501(c)(3) public charity in June 2014. Dena is a trained peer-support group facilitator at the Mood Disorders Support Group of New York (MDSG)—after which the Refa’enu mood disorder support groups are modeled—and is also on the advisory board of Elijah’s Journey, an organization dedicated to increasing suicide awareness and prevention in the Jewish community. She writes an op-ed column for The Jewish Standard (under her maiden name, Croog). Her first op-ed column in February 2014—“I have bipolar disorder”—which addressed the need to speak openly about mood disorders in the Jewish community, won an Excellence in Journalism Award issued by the New Jersey Society of Professional Journalists. Since then, Refa’enu has been featured in articles and columns in both The Jewish Link of New Jersey and The Jewish Standard. Dena continues with her own writing, which she hopes to see published before the death of the printed word.
