Tomorrow will be the last day for Crain’s New York Business‘ editorial director Greg David, who is leaving the pub after more than 33 years at Crain Communications.

David is leaving his full-time gig at Crain’s to become the director of the business and economics program at the CUNY Graduate School of Journalism. “I have been teaching there for three years and it is an exciting opportunity,” he said in an email today.

However, David said he will still write a weekly column in Crain’s print edition as well as a daily blog on the Web site, and “may do other editorial projects from time to time,” so he won’t be far from the pub. He’s also planning on making media appearances on WCBS Newsradio 880 and WNYC, giving speeches and moderating panels in addition to his duties at the journalism school.

During his long career at Crain’s, David spent 23 years as editor of the paper, joining just a few months after it started publishing in January 1985. In September 2008, the paper hired a new editor, Xana Antunes, and David moved into the role of editorial director. He previously worked for The Sarasota Herald Tribune and The Charlotte Observer.
