 She Said, I began my career in New York City as a Controller. But by what I call a beautiful accident, I transitioned into real estate — and immediately recognized something important: the Spanish-speaking community lacked guidance, representation, and access.

I saw hardworking families with dreams but no one to lead them through the system.That’s when I knew my purpose. Just like my father served his people in Peru, I chose to serve mine here. I stepped into real estate not just as a career, but as a mission — to educate, empower, and lead immigrants toward the American Dream of homeownership.
