The CEO and co-founder of a Lenexa company is stepping down.

Keith Plumb announced Jan. 31 that he would leave Executive AirShare in 30 to 60 days. He co-founded the company in 2000 and has served as COO, president and CEO.

Plumb will remain CEO until he leaves; CFO John Owen will serve as interim president during the transition. The company has begun a search for a new CEO.

“All of the remarkable accomplishments and successes that we shared over the last 18 years would not have been possible without the aviation passion, dedication and hard work by the EAS family,” Plumb said. “I leave Executive AirShare feeling privileged and honored to have had the opportunity to meet incredible people, travel to amazing destinations and gain valuable experience leading the professional men and women at Executive AirShare.”

Executive AirShare serves the central U.S. and Great Lakes region by managing a fleet of planes that each have fractional ownership. It also offers aircraft management and charter services through its subsidiary, Executive Flight Services.
