San Diego-based Guild Mortgage has grown significantly since 2007 and managed to stay successful despite the housing crisis, according to an article in U T San Diego. 

The mortgage firm grew from $1 billion in loan production at the end of 2007 to $6.4 billion last year, the article said.

Additionally, the company's servicing portfolio escalated from $2 billion in 2007 to $10 billion.

In the beginning of 2008, we believed that was the time to search for and pick up talent (from companies that folded). We took advantage of the dislocation of the market. In 2008 and 2009, we grew a lot. That’s when we got a lot of good people. That just fed on itself through 2010. We want to continue to expand.
