OC500 2025: TOM DONNELLY 

TOM DONNELLY 

CEO/PRESIDENT 

MAZDA NORTH AMERICAN OPERATIONS 

WHY: Heads Orange County’s fourth-largest automaker with almost 340 local employees as of October.  

IN THE NEWS: Hit record vehicle sales in 2024, with 424,382 units sold. Redesigned dealerships, more than 300 locations, represented nearly 90% of Mazda North American’s retail sales last year. For the first six months of 2025, Mazda reported 210,298 vehicles sold, up 3.9% from the year before.  

NOTABLE: Donnelly counts over 30 years in auto; joined Mazda in 2008 as a director of service and parts operations in Texas before moving up and eventually entered top role after 15 years. March marked a record in single-month sales, 43,097 vehicles, for Mazda.  

QUOTABLE: “Our record-setting performance is a testament to the hard work of everyone at MNAO and our dealer partners.”
