It’s one of the biggest companies you’ve probably never heard of.That’s how Foundation Financial Group CEO Paul Scott describes the mortgage services company that’s been at 225 Water St. since November 2004.Incorporated in Atlanta in 1994 as Homeowners Mortgage of America, the company opened its Jacksonville office almost six years ago and recently relocated its executive team here from its other offices in Atlanta, Savannah and Raleigh, N.C. The expansion to Jacksonville coincided with a change in Foundation Financial Group’s focus away from working with mortgage brokers and toward serving the retail residential mortgage market.
