Westcore Properties of San Diego has opened a new office in Irvine, as it seeks to expand its acquisition focus within Southern California, the commercial real estate investment firm announced April 2.

The privately held Westcore, which completed more than $250 million in office and industrial acquisitions in 2011, also has regional offices in San Francisco and Denver. The firm’s European offices are located in Geneva and London.

A company statement said Managing Director Neil Johnson will head the Irvine office, at 2030 Main St., Suite 1300. “Our new Orange County office will enhance our ability to identify and move quickly on assets that meet our investment criteria within Southern California, especially in the Orange County, Los Angeles and Inland Empire regions,” Johnson said.

Since its founding in 2000, Westcore Properties and its affiliates have acquired and managed more than $3.9 billion in industrial and office assets, including 550 buildings totaling more than 25 million square feet, the statement said.
