Here’s a milestone for the male-dominated investment sales arena. Darcy Stacom, an executive vice president at Los Angeles-based CB Richard Ellis, was the firm’s top grossing sales broker on a national basis last year. This is the first time in CBRE history that a woman has achieved such lofty status, according to the firm.

Stacom and her New York City-based team brokered roughly $7.1 billion in office and multi-family property sales last year. They also beat out 2,200 other CBRE sales brokers for the title.

Four years ago, CB Richard Ellis lured Stacom away from Cushman & Wakefield with a seven-figure signing bonus. Her partner, Bill Shanahan, also followed her to CBRE. Stacom was Cushman & Wakefield’s top global producer for two years leading up to her defection.

“Darcy has long been one of the most productive brokerage professionals in the New York market, and she took her performance to an even higher level in 2005,” says Brett White, president and chief executive officer at CB Richard Ellis.

“The volume of business she generated is truly remarkable, and stands in testament to the strategic advice and precise execution she offers New York City investors on a daily basis,” adds White. In New York City alone, Stacom and her team last year sold $4.6 billion of office buildings. According to CBRE, that represented 40% of all office investment sales activity in Manhattan last year.
