Noblis Inc.’s senior vice president, chief financial and administrative officer and treasurer, Mark Simione, will retire July 8, 2022, the Reston-based not-for-profit federal contractor announced this week.

Gary Sladic, the company’s vice president of finance and accounting, has been appointed deputy CFO and will assume the top role after Simione’s retirement.

“As one of the first executives to help establish Noblis in 1996, my tenure with the company has been an incredible journey. I’m honored to have helped build and lead in such a phenomenal organization and team,” Simione said in a statement. “I am also pleased to pass the baton to Gary Sladic upon my retirement. Gary and I have worked together for the past 25 years, and I’m confident he’s the right leader for this next phase of growth.”

Simione and Sladic joined Noblis — then known as Mitretek Systems — in 1996. Simione serves on Noblis’ board of trustees and AllCom Global Srvices’ board of directors. Sladic has held several positions in the company’s finance department and has contributed significant work to the company’s merger and acquisitions during the past 25 years.

In September, Noblis won a five-year, $263 million Department of Defense contract to work on its Cooperative Threat Reduction program. In April, Noblis purchased McKean Defense Group for an undisclosed amount.
