The Collingwood Group named Mary Lou Christy senior vice president. Christy comes from Fannie Mae and joins Joseph Murin, the former president of Ginnie Mae, and Brian Montgomery, former Federal Housing Administration commissioner, at the firm, which provides advisory services to boards and senior executives at financial services companies. Murin, Montgomery and a few other partners formed the Washington-based company last year. Christy was most recently senior vice president of investor relations for Fannie Mae. She also led the mortgage-backed securities trading desk and was vice president of sales and marketing in the southwestern region during 24 years at the GSE. "This is an extraordinary opportunity to help clients succeed amidst the historic business and regulatory changes of the new decade,” Christy said. Write to Jason Philyaw.
