Christopher Asleson
Chris Asleson has been instrumental in the growth of CATCO since he joined the company as head of the construction division more than two decades ago. He developed relationships with reputable subcontractors as well as insurance adjusters while leading his staff to provide excellent service. He moved over to the account management side of the business and expanded the sales efforts in the St. Louis region and beyond. Not afraid to be hands-on, Chris developed a reputation with his clients as a problem solver. His customers know they only need to call Chris to get a project moving quickly and effectively. Chris took over the reigns of the Missouri branches in June of 2022 when Michael Hammack retired, effectively continuing our legacy in the St. Louis metropolitan area as a full-service restoration leader.
