O'Hara was born in Greenore, Ireland, in 1886. He emigrated to the United States on April 7, 1915 at age 27, sailing aboard the SS Cymric from Liverpool. He was the eldest of three brothers. His brothers Patrick and Jimmy were also golf professionals. Fellow Irish professional Pat Doyle was O'Hara's traveling companion aboard the Cymric which would find a watery grave just 13 months later on May 8, 1916 when it was sunk by a German U-boat during World War I.
Golf career
Early career
In Ireland he was first engaged at the Greenore Golf Club at age 17 in 1903, a position he held until 1907. His next job was at Monkstown in Cork Harbour where he laid out a 9-hole course.
Emigration to the U.S.
After arrival in the U.S. in 1915, he first worked at Pittsburgh Field Golf Club from 1915–18. In late 1919, he took up a post at Haworth Country Club in Haworth, New Jersey, and in 1920 was employed by Shackamaxon Country Club in Scotch Plains, New Jersey, where he joined forces with his brother Patrick. He remained at Shackamaxon until 1922. The two brothers were a tough pair to beat in four-ball matches on their home course as evidenced by a surprising 6 and 5 victory they had in 1920 over the highly favored duo of Harry Vardon and Ted Ray. O'Hara wasted no time getting his golf career going when he made a start in the 1915 U.S. Open at Baltusrol Golf Club. He didn't play his best golf, shooting 85 and 79, and failed to make the cut. His results were better in the 1917 Western Open where he finished tied for fifth behind Jim Barnes and Walter Hagen. In the 1930 U.S. Open he finished tied for 11th place and at the time was professional at the Westmoreland Country Club in Verona, Pennsylvania. O'Hara was known for not taking any backswing whatsoever on short putts. He would simply place his putter head about 3-4 inches behind the ball and hit the ball from that position.
In the 1920 PGA Championship held at the Flossmore County Club, located south of Chicago, O'Hara got off to a good start with a 1 up victory over Pat Doyle in the first round. He rode that momentum into the second round and defeated Alex Cunningham by a convincing 5 and 4 margin. His upset bid in the third round was spoiled when he lost to George McLean in a closely contested match that wasn't decided until the 38th hole. His final position in the tournament was a tie for fifth place.
The 1929 U.S. Open was held June 27–30 at Winged Foot Golf Club in Mamaroneck, New York, a suburb northeast of New York City. Bobby Jones won his third U.S. Open title in a 36-hole playoff, trouncing Al Espinosa by 23 strokes on the West Course. O'Hara played steady golf, carding rounds of 74-76-73-78=301, and won $300 in prize money. He finished tied for eighth place.
Death
O'Hara retired from Green Oaks Golf and Country Club in 1948. He died on April 11, 1977, aged 91. Both he and his wife Hanora are interred in St. Joseph's Cemetery in Hackensack, New Jersey.
