Denver-based air charter firm Mountain Aviation was acquired by an unidentified private investment group earlier this week. Rich Bjelkevig, who founded the turboprop and jet charter firm in 1993, will continue to serve as the company’s president. Cam Kenyon, previously the executive vice president of operations at WestJet Airlines and the president of Lynx Aviation in Denver, has been appointed Mountain Aviation’s executive director. In addition to retaining a focus on its existing Rocky Mountain region aviation clients, the company will seek to provide additional aviation services to the oil and gas industry and government services markets.
