The Martineaus joined NEXA Mortgage during a pivotal growth phase — when a team of 800 Loan Officers felt big. Today, NEXA is home to over 2,000 professionals nationwide, and Diane & Eric have been proud contributors to that expansion. Their long-standing commitment reflects not only their belief in NEXA’s model, but also their trust in the power of education-driven lending.
Together, Diane and Eric offer a full suite of residential mortgage solutions, including VA, FHA, USDA, Conventional, and Down Payment Assistance programs. They specialize in helping first-time homebuyers, military veterans, and credit-challenged borrowers navigate the lending process with confidence.
Clients know them for their responsiveness, reliability, and willingness to go the extra mile — ensuring every borrower understands their options and secures the best possible financing strategy.
When they’re not serving clients, Diane and Eric enjoy giving back to their community, continuing their education in the evolving mortgage landscape, and celebrating each homeowner success story — one family at a time.


Ever wonder how NEXA Mortgage became the largest and fastest growing Mortgage company in the Nation? We explain how NEXA’s focus on Loan Officers makes the difference.
After years in the Industry Diane wasn’t getting the support she need. Finally we found a company “that was build around loan officers.”
Mike Kortas, the owner says, “It wasn’t about building something that makes the owners filthy rich, but instead something that allowed the Loan Officers to Maximize Themselves.”
“That was the problem we saw,” the loan officer needed to be the nucleus of the company.
