therealdeal.com – Cushman & Wakefield’s Paul Massey is one step closer to challenging Mayor Bill de Blasio in 2017.

The co-founder of Massey Knakal Realty Services is tapping SL Green executive David Amsterdam as his campaign manager if and when Massey decides to run for mayor.

Amsterdam joined SL Green in 2011 as a vice president for leasing. He represented the firm in house on its deal to lease 53,000 square feet at 328 West 34th Street to Music Choice earlier this year.

“Yes, Mr. Massey has had extensive discussions with David Amsterdam, whom he greatly trusts and admires,” a spokesperson for Massey told Commercial Observer. “And, yes, if Paul were to run for mayor, Mr. Amsterdam would be his number one choice to serve as campaign CEO. That’s all I can say for now.”
