Prior to his time in the Texas Senate and House, Pat enjoyed a decades-long successful entrepreneurial career, having founded over a dozen successful companies.

To raise funds and awareness for pediatric cancer research, Pat entered what has been billed as "the world's greatest endurance challenge" in 2016. He completed the World Marathon Challenge, a race where competitors attempt to run 7 marathons on 7 continents in 7 days, on January 29, 2016, becoming just the 15th person in the world to do so successfully. He was also the first (and still only) person to finish the World Marathon Challenge with no previous marathon experience.

Congressman Fallon is a proud graduate of the University of Notre Dame where he played varsity football under legendary coach Lou Holtz and was a member of the 1988 National Championship team. Upon graduation, Pat received a commission to serve as an officer in the United States Air Force where he was stationed at Sheppard Air Force Base in Wichita Falls, TX.

Pat has been happily married to his lovely wife, Susan, for 19 years and they have two boys, Thomas (16) and Mac (13).
