Quicken Loan Mortgage Services, the division of Quicken Loans that partners with financial institutions including credit unions, has been growing quickly, the firm announced.

It also reported it will add 75 employees by the end of 2012 to support its growing business needs.

The division currently employs 150 and expects to expand beyond 200 by the end of the year and said it currently works with more than 800 partner financial institutions, the company said. It also predicted it will surpass 1,000 partners and $1 billion in monthly loan volume by the end of 2012.

The firm did not break out how many of those financial institutions are credit unions.

It will also move to a new 20,000-square-foot office space, which is more than double the current QLMS location in Charlotte, N.C., by the end of June.

“We are growing very quickly – faster than even the most optimistic models we developed when we launched QLMS two years ago,” said Tod Highfield, vice president of QLMS. “Right now we are in explosive growth mode, adding both partner financial institutions and team members. It is really a fun time to be part of this team – and we see continued opportunity ahead of us.”
