The real estate executive who signed the largest private sector lease in D.C. history has just changed firms.

Dan Dooley left his position as Carr Properties' chief operating officer and is joining Tishman Speyer this month. Dooley posted the change on his LinkedIn page and Tishman Speyer confirmed the hire to Bisnow.

Dooley will serve as managing director and head of leasing and asset strategy for the D.C. region for Tishman Speyer, which owns 12 office properties totaling over 4.7M in the region. He previously worked for the New York City-based developer between 2001 and 2014 before joining Carr.

"Dan is well known as an outstanding leader in the D.C. market," a Tishman Speyer spokesperson said in an emailed statement to Bisnow. "We found an opportunity to bring him back in a leadership role as we continue growing in the market, and we are really pleased.”

While at Carr, Dooley led the effort to sign Fannie Mae to a 752K SF lease at Midtown Center, the District's largest private sector lease. Following that lease, CREBA in 2016 named Dooley the top leasing agent in the region, and he took home the association's James L. Eichberg Broker of the Year Award. Dooley's team also signed WeWork for 110K SF at Midtown Center in April.
