He was admitted to the bar in 1900, and practiced in New York City.
He was Lieutenant Governor of New York from 1921 to 1922, elected on the Republican ticket with Governor Nathan L. Miller at the New York state election, 1920. On September 26, 1922, Wood resigned and was appointed a judge of the New York Court of Claims to fill the vacancy caused by the resignation of William D. Cunningham.
In 1925, he ran for the New York Supreme Court but was defeated.
He was Chairman of the Nassau County Republican Committee from 1927 to 1929.
He resided in North Lynbrook, New York, a community he created when the Village of Malverne became an incorporated village in 1921. Wood did not want to live in a village for fear of higher taxes. To avoid this, he changed the borders of the new village so that his home would not be included. He died in 1962 in Hempstead, Nassau County, New York.
