Knoxville Chamber of Commerce Director Larissa Van Donselaar says she’s looking forward to Roger Brook’s visit to Marion County. She says that the world-renowned tourism expert will give great input on what they’re doing right and where they can improve in terms of tourism opportunities. Van Donselaar says his June 7th presentation is a great opportunity to learn, noting that those results have to be taken seriously. Community and business leaders are invited to hear to take part in that presentation and workshop at Pella Christian High School. Early bird registration ends May 1st and can be completed at the Marion County Development Commission.
