Nine-year-old John Mullen arrived in America from Ireland with his family in 1856. They settled in New York where John learned the trade of miller. At age nineteen, John went west to Kansas to work. In 1871 he moved on to Denver, Colorado. He was an experienced miller but found it hard to obtain a job in the milling industry in Denver. He eventually went to work for O. W Shackleton and Charles Davis at their West Denver Flour Mill. As a progressive businessman, Mullen built the Colorado Milling and Elevator Company and bought the Excelsior Mill from John W. Smith.

Former Mullen Home

In 1925, the basement of the church was finished, but funds had run out. Because Catherine Mullen was an avid supporter of the new church, J. K. “felt compelled to provide support to the parish in her memory" when she died that year. He donated more than $65,000 to the church to help cover the remaining building costs. St. Cajetan’s Catholic Church was completed in 1926.
