JLL Assembles New Team to Steer Southeast Financial Center

Mr. Cartwright has successfully directed the exclusive leasing of Southeast Financial Center for over two years, including 240,000 square feet of lease transactions.
“I am thrilled to continue overseeing the leasing of the most prestigious business address in the southeast.

Located at 200 South Biscayne Boulevard in downtown Miami, Southeast Financial Center is comprised of two buildings: a 1.225 million square foot 55-story Class A Office Tower distinguished by its striking “saw-tooth” design on the northeast corner of the façade and a 15 story Annex Building which houses the popular Downtown Athletic Club and 1,200 parking spaces. Connecting the Office Tower and Annex buildings is a 30,000 square foot outdoor plaza landscaped with shade trees and a variety of lush native plantings. A steel and glass canopy attached 150 feet from the ground provides a unique architectural connection between the two structures, and adds an aesthetically pleasing ambiance to the plaza.
