The Story Starts With Sonia
She built a reputation for transforming brands, developing award-winning creative and helping establish Greteman Group and Wichita as a center of aviation marketing expertise. An early relationship with Learjet opened the door to an industry that would take our team around the world, working with aircraft manufacturers, flight support companies and aviation businesses of all kinds.
A Legacy That Keeps Moving
After more than three decades of leading the agency, Sonia transitioned ownership to Ashley Bowen Cook, who had worked alongside her for more than 20 years. Adopting our new name, Alpha Charlie, in 2026, that new chapter was built on the foundation Sonia created.
The name changed. The spirit didn’t. Alpha Charlie carries forward the commitment to creative thinking, strong relationships, aviation expertise and work that makes a difference, while looking ahead to what’s next.
