“I have been watching Sierra for a while and they have impressed me in their approach to management and the energy they seem to exude,” Poblocki says. “And now, with their partnership with Lee & Associates, the leverage and support this will mean to me will be ideal in how I can service my clients.”

During his tenure at Grubb and as managing director at CBRE, the 30-year veteran of the CRE industry has handled management assignments from Midtown to Downtown, including the Sony Building on Madison Avenue, 420 Fifth Ave., 125 Broad St., 67 Broad St., 50 Broadway, 14 Wall St., 22 Cortlandt St., 99 Church St., 55 E. 59^th St., 460 Park Ave., 125 Park Ave., 150 E. 42^nd St., 800 Second Ave., 475 Riverside Dr., the Paley Foundation Building at 1 E. 53^rd St. and the Riverside Church and Union Theological Seminary.

Sierra currently manages office properties such as 875 Avenue of the Americas, 401 Washington St., 12 East 46^th St. and 648 Broadway, as well as mixed-use residential buildings at 1125 Lexington Ave., 971 1^st Ave., 244 E. 46^th St., 783 Lexington Ave. and 12 East 60^th St., according to the company website.

James Wacht, president of Sierra Real Estate, says that Poblocki's hire will be "instrumental" in raising the profile of the company's commercial property management services as the firm increases its footprint in Manhattan. "To get someone with as much talent and expertise as John has is phenomenal," he says, in a statement.

Earlier in the year, the firm has also hired ex-Grubb brokers Howard Rosen and John Cannon. Poblocki wasn't immediately available for additional comment.
