LOS ANGELES-MPG Office Trust Inc. has named David L. Weinstein as its new president and CEO, effective immediately. The new MPG chief, a partner at New York City’s Belvedere Capital, takes the reins a week after former president and CEO Nelson Rising quit in a split with the board.

In addition, the company said that it has retained Frederick E. Chin and his firm Atalon Management Group LLC to provide restructuring advice to M:G. Chin most recently led efforts to restructure and resolve various loan and other obligations associated with Lake Las Vegas, a 3,600-acre master planned community in Henderson, NV.

Weinstein has served as an independent director on the MPG board since August 2008 and served as a member of the audit committee and nominating and corporate governance committee until his appointment as president and CEO. He also serves and will continue to serve on the company’s finance committee.

Before becoming a partner at Belvedere Capital, Weinstein was a managing director of Westbridge Investment Group, a real estate investment fund focused on hospitality. From 1996 to 2007, he worked at Goldman Sachs & Co., initially in the real estate investment banking group (focusing on mergers, asset sales and corporate finance), and from 2004 to 2007, in the special situations group focused on real estate debt investments.

MPG said in a prepared statement that under Weinstein the next phase of the REIT’s restructuring efforts will focus on the company’s core Downtown Los Angeles properties and “will include proactively working with lenders and special servicers in an effort to reduce the company’s leverage, extend debt maturities, maintain appropriate funds for value-creating leasing and capital expenditures and ensure adequate cash flow with respect to these properties.”

The first phase of the company’s restructuring efforts is substantially complete and resulted in the resolution of 18 assets, relieving MPG of approximately $2 billion of debt obligations and potential guaranties of approximately $150 million, according to the statement.
