DENVER: MGA Communications chairman Mike Gaughan passed away on August 25 at age 77, according to media reports.
The Denver Business Journal cited post-surgical "complications" as the cause of death.
Nearly three decades ago, Gaughan started the firm with Jeff Julin and Cricket Smith, according to MGA’s website.
As a teen, Gaughan was a "marquee boy," which inspired him to form his own company, Entercom PR and Advertising, which specialized in movie promotion, according to his profile page on MGA’s website.
He also served as the director of advertising and PR for theater operations at the Cooper Foundation, working with celebrities including Sean Connery, Charlton Heston, Henry Fonda, and Jimmy Stewart.
Gaughan’s approach to communications was to "understand what motivates the people you are trying to communicate with. From this understanding, you can create an open forum to discuss the truth and the issues that separate people," according to his MGA profile page.
Memorial arrangements are still in the works, MGA said on its Facebook page.
"I have received so many beautiful and funny remembrances regarding Mike and the life he led," Julin posted to the page last week. "But the real tribute is the number of people who loved him and celebrate him now. We both believe that the true treasure of life is friendship."
PR pros on Twitter mourned the loss of Gaughan:
