Kilroy, who started his career with PRI in 1990, led the company’s editorial operations for 22 years until he was elevated to GM following PRI’s sale to the Specialty Equipment Market Association (SEMA) in 2012. For the next four years, he oversaw the day-to-day management of PRI and produced the annual PRI Trade Show while guiding the overall direction of PRI’s media and communications efforts.

A graduate of Cal State Fullerton, he was widely known and respected throughout the industry as an honest, hard-working professional with a passion for motorsports and those who made their living in the trade. He maintained countless friendships among PRI staff even after his departure from the company in 2016.


“John really was a pioneer in the industry,” said PRI Trade Show Director Karin Davidson. “Everyone knew him, whether you were at the Show or at the track. John was the go-to guy here for so long, and for so much. It’s hard to put into words the impact he had at PRI.”

In his final editorial for PRI Magazine titled “The Next Turn,” Kilroy spoke of his pride in having taken the concept of a trade show and business publication for racing professionals to “previously unimaginable heights.”

“I’ve had a great run here at PRI,” he wrote. “Along the way, I had the great fortune to work in an industry that taught me a lot about how to live this life. Thank you all for chasing after it the way you did. You inspired me throughout my 26 years.”


A resident of Orange, California, Kilroy leaves behind a wife and three children. He will be missed by all of us who knew, worked with, and learned so much from him through the years.
