David Ogilvy is closing David Ogilvy & Assoc. after 34 years of brokering some of the town’s largest residential sales. The Greenwich Time was the first to report the news.

Ogilvy is bringing eight agents from his former firm with him. At the same time, Ogilvy is breaking his affiliation with Christie’s International Real Estate.
