He grew up in Tallahassee, Florida and attended Maclay School where he held numerous student leadership positions, active in sports, and graduated in 1987.

His great-grandfather, Colonel John B. Richardson, Sr., earned the Distinguished Service Cross, the nation's second highest award for valor, during World War I,[14] and his paternal grandfather served as an infantry battalion commander in the European Theater during World War II and commanded the 5th Cavalry Regiment in the 1st Cavalry Division in Japan and Korea 1953–54.

His maternal grandfather, Dr. H. Donald Loucks, graduated from the University of Florida, completed ROTC and served as a math professor and basketball coach at West Point, then a professor of physical education and the first NCAA basketball and tennis coach at Florida State University and was a 1985 inductee into the FSU Athletic Hall of Fame.

After the tour in the Pentagon he deployed to Iraq in the fight against ISIS in Mosul serving as the Deputy Commanding General for 1st Infantry Division/CJFLCC-Operation Inherent Resolve.

In September 2020, Richardson assumed duties as the Deputy Commanding General for III Corps, Fort Hood, Texas following the aftermath of the April 2020 murder of Army Specialist Vanessa Guillen.

Over the next year, Richardson would assist the III Corps Commander in leading the reforms recommended by the Fort Hood Independent Review Committee (FHIRC), to improve systemic issues of discipline, poor morale, and safety at the Nation's second largest Army installation.

The ensuing III Corps "People First" initiatives would set a foundation for the Army's transition to an inter-war period and focused on balanced and holistic readiness (People/Equipment/Training) required during an era of Great Power competition.

As a Cavalryman his warfighting philosophy is simple: Seize and maintain the initiative, attack, penetrate, exploit, pursue the enemy relentlessly, and win decisively.
