Guardian Protection Services, ranked No. 6 on the SDM 100, announced that President Joe Colosimo will resign effective May 12.
The resignation comes just over one month after the 2017 Guardian Protection Services Authorized Dealer Conference was held at ISC West in Las Vegas. Guardian said in a statement, “Colosimo will be taking some much-needed time off and plans to return to the security industry as soon as possible,” with no further word on why Colosimo is stepping down.
