SRA International (SRX) operating chief David A. Kriegman will leave Sept. 15 to pursue other opportunities.

The Fairfax, Va., technology and strategic consulting company said CEO Renato A. DiPentima will take Kriegman's duties until a successor is named.

"Throughout his tenure, David has been an important part of the company's success," said DiPentima. "He has helped SRA expand current business, hire and retain talent, and lead important projects with customers across the federal government. We thank him for his contributions and wish him well in his future endeavors."

Kriegman said, "I am privileged to have been part of the SRA team and to have played a leadership role in bringing the company into the top tier of federal government services providers. I have decided to retire from the company after 23 years to pursue other opportunities."
