The Executive Board and Management

Visionary entrepreneurs introduced the Nomad concept of elite executive aviation in 2008. It’s a business strategy aimed at excellence in individualization, not standardization. Client loyalty is the goal. Nomad’s truly the only aviation firm designed specifically to serve a select, exclusive clientele.
