O'Mahony (spelled "O'Mahoney" during his wrestling career) was brought in to America by a Boston promoter Paul Bowser who had a plan of creating the biggest Irish wrestling star since William Muldoon.

On 1935-06-27, O'Mahoney defeated Jim Londos in Boston for the world heavyweight championship, recognized by New York State Athletic Commission and National Wrestling Association. After about a month later, he defeated Ed Don George in Boston to win the American Wrestling Association title to unify the three major versions of the world heavyweight championships.

His reign as the undisputed world heavyweight champion ended when Dick Shikat defeated him on 1936-03-02 at Madison Square Garden in New York City to become a new champion while O'Mahoney continued to be recognized as the champion by AWA in Boston. However, he lost the AWA title to Yvon Robert four months later.

O'Mahoney passed away on 1950-11-03 in his homeland of Ireland at the young age of 38 due to an injury from an auto accident.
