Pittsburgh-based staffing provider System One acquired TPGS, a solutions provider to the intelligence community, Department of Defense and US federal clients.

TPGS will maintain its brand and operate as part of GAP Solutions Inc., a System One company. The transaction closed Sept. 19; terms were not disclosed. The TPGS leadership team will remain with the organization.

Headquartered in Reston, Va., TPGS provides cleared teams of IT professionals to government contractors.

The deal follows System One’s acquisition last month of NTP Wireless, a wireless site acquisition company headquartered in Chicago, and its January acquisition of Juvo telecom, a telecom, wireless and engineering services and staffing company. 

“TPGS expands our mission-critical support and technology services to better serve our federal customers and partners, which is fundamental to our long-term growth strategy,” said Diane Pairel, President, GAP Solutions.

System One ranks No. 21 on Staffing Industry Analysts’ 2018 list of largest staffing firms in US, and No. 11 on the global list of largest engineering staffing firms.
