Green River Capital, a REO asset management and loss-mitigation provider based in Utah, named Lorenz Schwarz chief operating officer. Schwarz replaces Stephen Sherman, who ascended to the operating chief post in early October, and also will lead the GR Financial and Infinity Valuation Services unit. Sherman joined Green River in 2008, holding several upper management positions, including senior vice president. Schwarz brings more than 20 years of commercial and residential mortgage servicing experience to Green River. He had been president of Phoenix Asset Management and held management positions for Select Portfolio Servicing, Wilshire Credit Corp, and J.E. Robert Co. prior to joining Green River. Schwarz joins the company as it expands REO services to commercial properties.  The company will be able to handle commercial property repossessed by client lenders through services such as disposition of assets, maintain properties, verification of leases, and property valuation. Additionally, Green River plans to focus its REO efforts toward small-balance properties and add specialists to its nationwide agent network. Write to Matthew Torres
