SI, GTSI appoint new managers

GTSI has hired an executive who formerly led a storage vendor’s solutions group to head the company’s services operation, while SI International officials promoted the company's chief operating officer to chief executive officer.

William Weber was named GTSI’s vice president of professional services. That unit provides a range of services, including requirements assessment, project management and maintenance. In addition to managing services, Weber will also be responsible for GTSI organizations involved in integration and managed fulfillment services. Weber reports to Barry Culman, GTSI’s chief business architect.

Prior to joining GTSI, Weber was vice president of client solutions at CNT, a storage networking vendor that McData acquired last month.

SI, meanwhile, has appointed S. Bradford Antle to succeed Ray Oleson as the company’s chief executive officer. Antle currently serves as SI International’s president and chief operating officer. He will retain his role as the company’s president. Oleson will continue as executive chairman of the board after Antle becomes CEO.

Oleson said in a statement that the management shift will let him devote more attention to strategic business planning for long-term growth initiatives and future acquisitions.

SI has closed two acquisitions in the last seven months: Bridge Technology and Shenandoah Electronic Intelligence. The acquisitions were aimed at broadening the integrator’s customer base among intelligence agencies and the Homeland Security Department, respectively.

SI will discuss the management changes Tuesday during its quarterly earnings conference call.
