Meet Maria Jose "MJ" vanMastrigt

I'm Maria Jose “MJ” vanMastrigt, a Brentwood-based real estate professional with eXp Realty, serving buyers and sellers throughout Contra Costa, Solano, San Joaquin and Alameda Counties.

I was born and raised in Nicaragua, where I learned early the importance of hard work, dedication, and taking care of people. I studied Tourism Management in college before joining my family's international insurance business, where I had the opportunity to work with people from around the world.


Eventually, life brought me to the United States, where I met my husband, started our family, and made Brentwood our home. As a wife, mother, and local resident, I understand that choosing where to live is about much more than a house—it's about finding a place that feels like home.

Your Local Real Estate Professional 


After starting our family, I knew I wanted to return to a career centered around working with people. Real estate was a natural fit.


Today, I help buyers and sellers navigate the real estate process throughout Brentwood and the surrounding communities. Whether you're purchasing your first home, searching for your next one, relocating, or preparing to sell, my goal is to make the process clear, personal, and as stress-free as possible.


I believe good real estate service starts with listening. Every client has different priorities, and I take the time to understand what matters to you before helping you determine the best path forward.


I live in the community I serve, so this isn't simply a market I work in—it's home.


Why Work With MJ?


Real estate is personal. Buying or selling a home is one of the largest financial decisions most people make, and you deserve an agent who communicates clearly, responds when you need help, and advocates for your interests throughout the process.


I bring local knowledge, professional experience, attention to detail, and a personal approach to every client I work with. My goal isn't simply to complete a transaction—it's to make sure you feel informed and confident from our first conversation through closing.


Whether you're buying, selling, relocating, or simply trying to understand your options in today's market, I'm here to help.


For my Spanish-speaking clients, I'm happy to provide real estate services in English or Spanish.


Let's Talk About Your Next Move


Thinking about buying or selling a home? Maybe you're not ready yet and simply have questions about the local market. That's okay too.


I'd be happy to talk with you, answer your questions, and help you determine what makes sense for you and your family. 

Giving Mariela and her daughter the keys to their dream home.

Congratulations to first-time homeowner Mariela!
