Lake Charles, Louisiana-based Citadel Completions has rebranded as Citadel Aviation to reflect the company’s expanded global aviation services, not just VIP aircraft completions. The move is part of new CEO Greg Colgan’s marking “a new chapter,” which includes becoming “the preferred global partner for maintenance, modification, refurbishment, and completions in the VIP and elite custom aircraft market.”

Growing demand in the VIP aircraft market led to the expansion to full-service capabilities that include custom completion and refurbishment projects, fleet services, and maintenance. Colgan took on the CEO role at Citadel in August 2025, having previously worked as CEO at air carrier maintenance provider MRO Holdings.
