Meet Our Team

In 2007, Doris de Leon founded Mardel Realty & Loans to help home buyers navigate one of the most challenging financial decisions in their lives.

Mardel Realty & Loans is a real estate brokerage and mortgage company based in Hercules, California, serving homebuyers, homeowners, and sellers throughout the East Bay, including Contra Costa County, Alameda County, and Solano County. We provide comprehensive real estate services and home financing solutions, including conventional loans, jumbo loans, FHA loans, VA loans, USDA loans, non-QM loans, and mortgage refinancing.

We proudly serve clients in English, Chinese, and Spanish. Whether you're buying your first home, refinancing your current mortgage, or selling your property, our experienced multilingual team is here to guide you every step of the way.

Originally, Doris wanted to name her company “Dordel” for Dor(is) + de + L(eon). However, she didn’t love the way “Dordel” sounded, so she went back to the drawing board.

That’s when inspiration struck a little closer to home. Doris decided to name the company “Mardel” after her husband, Mario de Leon, blending family and partnership into the foundation of her business.

Mardel represents teamwork, commitment, and the belief that building a home is just as much about family and community as it is about financing. And from day one, that mindset has shaped the way we at Mardel Realty & Loans serve our clients: with care, trust, and long-term relationships at the heart of everything we do.
