John O’Mahony, who worked as an editor, reporter and columnist for the New York Post for 12 years, died Friday in Manhattan at age 63 after suffering a heart attack.
O’Mahony began working at The Post in 1993, and within a year he was back in his native Ireland covering the Northern Ireland peace process as a Post correspondent.
In 1999, he became a news-features editor and in 2001 he was promoted to associate city editor.
Genial, hardworking and possessed of a charming brogue, he was always amenable to a new idea and an after-work nightcap with colleagues.
Lately, he had been writing frequently for Bloomberg Businessweek and producing and editing through Blossom Trail, the company he founded with ex-wife and longtime friend Maya O’Mahony.
“He was a good man and Ill miss him terribly,” Maya told The Post Saturday.
