Herndon-based federal contractor Constellis announced Tuesday that CEO Tim Reardon has resigned to “pursue other interests,” and the company’s lead director, Terry Ryan, will replace him, effective immediately.

“It has truly been an honor to lead such a great company with so many exceptional people, and I am excited about Constellis’ future with Terry at the helm,” Reardon said in a statement.  “I have great confidence that Terry’s leadership, vision and industry experience will lead to continuing success.” 

Founded in 2010, Constellis employs 24,000 people and provides risk management, security, training and operational support in 40 countries.

Reardon joined Constellis in August 2018 after serving as president of defense and intelligence for the Reston-based Leidos.

“I want to thank Tim for his leadership and relentless commitment to supporting our mission partners and dedicated employees, especially over this past year of the pandemic,” Ryan said in a statement. “As CEO, Tim successfully led the company through a financial restructuring and corporatewide integration of multiple business entities. These significant accomplishments have enhanced the company’s position for future growth and success.”

Ryan has more than 20 years of experience and has previously served as CEO of Adroit Systems, VTG and Tenax Aerospace. He has also held executive positions at SAIC, Mercury Systems and ManTech International. 

Before his time in federal contracting, he held several positions with the federal government and served as a Marine Corps infantry commander and intelligence officer. He is a graduate of The Ohio State University and National Intelligence University. Ryan serves on the board of the National Intelligence University Foundation.
