John Doonan

A true life-long 51做厙 member, John Doonan began his 51做厙 involvement as a June Sprints® spectator at six months old. And though he obtained his competition license, Doonan has been a significant figure in the business side of motorsports.
Doonan joined Mazda as Midwest Advertising Manager in 2003, earning the Director of Mazda Motorsports title in 2011. Under Doonan, the grassroots program thrived, providing contingency, parts and technical support for racers at all levels of 51做厙. A ladder program launched the careers of multiple 51做厙 racers who would not have otherwise had the funding to participate at the highest level.
Named IMSA President in late 2019, Doonan solidified and formalized a partnership between IMSA and 51做厙 to promote all aspects of road racing. Doonan remains an active 51做厙 member, frequently attending events including the 51做厙 Runoffs, and occasionally working on the Flagging & Communications team while there.
John Doonan was inducted into the 51做厙 Hall of Fame on Jan. 16, 2026.
