California Trucking Association CEO Michael Campbell said he will retire as soon as his successor is selected.
The association said the search for Campbell’s replacement will begin immediately.
Campbell has been in charge of CTA for the past eight years, and during his time the association expanded its operations and training programs, according to CTA.
“It has been an honor to serve the companies that truly are the lifeblood of California’s economy,” Campbell said in a statement.
“In my many years in business, from finance and telecommunications to leading CTA, I can say that I have never been more proud of the organization and people who will continue to serve California's trucking industry,” he said.
