Goldman Oil Banker Montgomery Said to Leave for Buyout Job

William Montgomery, a senior Goldman Sachs Group Inc. banker to the oil and gas industry, is leaving the firm’s Houston office and plans to join a local private-equity firm, said a person with knowledge of his plans.

Montgomery, 49, may join Quantum Energy Partners later this year, said the person, who spoke on condition of anonymity. His retirement is effective May 31, Goldman Sachs said in a memorandum last month that was confirmed by Andrea Rachman, a Goldman Sachs spokeswoman.
