In the fall of 1894, Hollister took time off from his legal studies to accept a position as physical director and football coach at Beloit College. An account from the Beloit College Hall of Honor, to which Hollister was posthumously inducted in 1980, notes: "In 1894, Beloit alumni interested in seeing the athletic program expand provided funds to hire a coach for one year. The subsequent appointment of John Hollister as the first physical training instructor and coach began a rich athletic tradition at the College."[4]
After serving the 1894–95 academic year at Beloit, Hollister returned to the University of Michigan to complete his legal education, receiving an Ll.B. degree in 1896. After completing his legal studies, Hollister became the head football coach at the University of Mississippi in 1896, leading the team to a 1–2 record.[8]
In November 1897, Hollister married Margaret Hayden Reustle. They had a daughter, Margaret, in 1904.[1]
In 1898, Hollister returned to coaching, serving as the football coach and athletic director from 1898 to 1903.[8] He also served as the head football coach at Morningside College in Iowa from 1908 to 1910. Hollister compiled a career college football record of 50–39–10.[8]
Hollister later worked as a publishing executive in Chicago.[4] At the time of the 1920 Census, Hollister was listed as a resident of Chicago with a wife (Margaret, age 38) and a daughter (Margaret, age 15), and a job as an accountant in the machinery industry.[9] He died on March 8, 1950, in Chicago.[1]
