A 3,000-employee telecommunications and electrical firm will move its HQ from Dulles to Greensboro Station in Tysons, part of The Meridian Group's 4.2M SF The Boro project.

M.C. Dean signed a lease for 86k SF. In the exclusive picture above, Meridian's Gary Block inks the deal with M.C. Dean's Bill Dean.

“This is a tremendous story for Tysons and in particular Greensboro Station and The Boro,” Gary said in a release. “Company leaders are seeing the ongoing transformation of Tysons...They know this will help them to attract and retain the best employees, and better service their clients.”

The Meridian Group bought the 620k SF office complex, above, from SAIC in 2013 and recently scored $165M in financing for renovations. Meridian acquired the complex with 25% occupancy and with the M.C. Dean deal it is now more than 90% leased.

“M.C. Dean’s selection of Greensboro Station as its new headquarters is a clear endorsement of Meridian’s repositioning and redevelopment strategy,” CBRE senior vice president Terry Reiley, who helped broker the deal, said in a release.

Last month, Meridian signed its first office tenant to The Boro when media company Tegna signed a 60k SF lease at the 20-story Boro Tower.
