He served as Sheriff of Monmouth County, New Jersey from 1917 to 1920. One odd event during his tenure as Monmouth County Sheriff was the sale of liquor in 1920.

The fight referenced was the Dempsey-Carpenter fight in Jersey City - July 1921. On December 16, 1921, then Attorney General Dougherty requested Geran's resignation.
