I spent my early childhood in Los Angeles before my family moved to Tecate, Mexico, after my father a hardworking gardener suffered an injury that made staying in L.A. impossible. Like many families before us, we found a way. My siblings and I commuted across the border daily to attend school in East San Diego County, driven by my parents’ one wish: that we go to college.

In 2025, I took a new step. Alongside my continued community work, I began writing an informative blog focused on personal product analysis and first-hand usage reviews. After years of helping families navigate systems from school enrollment to public services I realized how often people, especially parents, are left overwhelmed when trying to choose what’s right for their homes, health, and children. I wanted to bridge that gap.
