ManTech's Dan Keefe to retire

ManTech International group president Dan Keefe will retire from the company effective June 30, according to a Thursday regulatory filing.

Keefe has led the company’s mission solutions and services group since 2013. This group comprises much of ManTech’s business with defense and federal civilian agencies.

Last year, the group defended its largest recompete in the five-year, $874 million contract to continue its sustainment and logistics support services for the Army’s MRAP ground vehicle fleet.

The retired Army brigadier general joined ManTech in 2011 from L3 Technologies, where he was a senior vice president and general manager.

Keefe’s announcement comes almost three months after Kevin Phillips succeeded ManTech’s founder and executive chairman George Pedersen as CEO. Also on Jan. 1, Rick Wagner succeeded the now-retired Bill Varner as president of the mission, cyber and intelligence solutions group.
