John began a career in journalism during his high school days when he served in a variety of roles, including news and sports reporter, for the Duncan Banner, a daily newspaper in his small Oklahoma hometown. He was the youngest sports editor in the newspaper's history by the time he attended the University of Oklahoma on a journalism scholarship. He graduated in 1978 with a bachelor of arts and sciences degree in journalism. Dwyer further developed his journalistic skills in radio as a play‐by‐play football and basketball announcer for several radio stations. He won the coveted position of sports director for the University of Oklahoma's 100,000 watt KGOU‐FM radio station. For seven years, he provided live, on‐air reports to America's largest radio networks of University of Oklahoma college football games. Except for a year in England during 6th grade, John lived in the Sooner State for 28 years before returning to Dallas in 1986 to attend Dallas Theological Seminary where he earned his Master of Biblical Studies. While there, Dwyer worked part time on the sports staff of The Dallas Times Herald, which at the time owned one of the five largest circulations of any daily newspaper in Texas. It was in Texas that he also met and married his wife Grace in 1988 and settled down to start his family.
