A brick and stone layer before entering politics, he was first elected to Dáil Éireann as a Labour Party Teachta Dála (TD) for the Kildare–Wicklow constituency at the 1922 general election. He was re-elected at the 1923 general election for the Kildare constituency and was again re-elected at the June 1927 and September 1927 general elections. He died in office in 1931 and the by-election caused by his death was won by Thomas Harris of Fianna Fáil.
