Riverstone Mortgage® is now Secure Mortgage Company

       At Riverstone Mortgage, our goal was to make the loan process as simple and worry-free as possible, and that is never going to change. As of January 1, 2019, with the retirement of Justin Navaretta, Riverstone Mortgage has stopped lending operations and Robin Mattern with Secure Mortgage Company has taken over lending operations.  Riverstone Mortgage had always been a Texas owned and operated residential mortgage loan originator through our strategic relationship with Secure Financial Services of Texas (DBA Secure Mortgage Company) and Robin Mattern has been been a Texas Senior Loan Processor and a Loan Officer for over 14 years.  Robin will continue the traditions of providing superior customer service, creating satisfied customers, working hard to satisfy financing needs, and exceeding the expectations of our customers.

       A strong belief in the "Customer for Life" principle of doing business is what fuels this company. Referrals from previous customers and real estate professionals have always delivered the majority of our company's business. We appreciate and thank you for the opportunity to continue to earn your business.


We offer both conforming and jumbo real estate loans.
