In 1939, John began working for P. F. Collier and Son. John's brother-in-law Earl Mason Roberts (husband of John's sister Florence) was working for the company and convinced him to work for them as well. John started off as a door-to-door book salesman in St. Louis, and within three months, he had been promoted to District Sales Manager in Indianapolis, Indiana. On 25 September 1939 in Indianapolis, John married Margaret Ann (Schneider) Foerstel, and gained an instant family (she had a daughter and son from her previous marriage). The family lived in Detroit for six years, where John and Margaret had two daughters and a son. They moved frequently, and lived in Chicago, Illinois; Los Angeles, California; New Hyde Park, New York; Redwood City, California; and Highland Park, New York. In 1956, John was appointed Vice President of P. F. Collier and began working at the New York office. He bought a home at 506 E. Saddle River Road, Ridgewood, New Jersey. He eventually became Chairman of the Board and President of P. F. Collier, President of Merit Students Encyclopedia, Inc., (which he created), and Senior Vice President of Crowell-Collier-Macmillan. Every year, he and Margaret traveled around the world and visited all the sales offices. On 15 July 1968, on his retirement, he was presented with the original Merit Students Encyclopedia Man of the Year Award. After six months, John had had enough of retirement and went back to work for two more years. In 1974, John and Margaret sold their house in Ridgewood and moved to an apartment in Ramsey, New Jersey.
John belonged to the Rubicon Masonic Lodge of Detroit, the Medina and Scottish Rite in Chicago, and Knickerbocker Country Club in Tenafly, New Jersey.
John died on 24 November 1977 (Thanksgiving Day) in New York City. He was buried at Valleau Cemetery in Ridgewood.
