Aaron Timmons, Jr. is the Director of Debate at Greenhill School. A veteran educator, and Greenhill Faculty Leader, Timmons has been inducted into the Hall of Fame of the National Speech & Debate Association, The Tournament of Champions, and the Texas Forensic Association. In 2000, he was listed as one of the top coaches of the 20th century by the National Speech & Debate Association. Timmons has published several educational publications and is a frequent presenter of workshops on debate pedagogy both domestically, and internationally. In 2014, Timmons was chosen as a Coach of the National Speech & Debate Associations version of the Olympic team for high school debate, the USA Debate Team. A former National Debate Coaches Association Educator of the Year, Timmons is one of only three coaches in the history of the National Speech & Debate Association to win National Championships in policy debate and Lincoln-Douglas Debate. He is the only coach to have multiple champions in both divisions, and in 2020, coached a World Schools and Poetry Interpretation champion as well. While the Greenhill Debate Team has a history of success, Timmons believes that the activity of Speech & Debate serves as a vehicle in aiding young people in telling their stories and preparing them to better themselves, and their communities.
