Rooted in a legacy of resilience and driven by a shared vision, our company's story began as a deeply personal endeavor, a family project sparked by the entrepreneurial spirit instilled in us from a young age. Our father, an immigrant from Colombia, arrived in America at 17, carrying little more than a bag of clothes and an unwavering dream to build a lasting legacy. Witnessing his dedication and contributing to his company since our teenage years, my twin sister and I developed a profound understanding of hard work and the importance of community support. Our journey is built upon a foundation of unwavering faith, passed down through generations. This enduring strength guides us, much like a cornerstone, ensuring that every decision we make aligns with our commitment to service and the betterment of our communities. Inspired by our father's journey and guided by a commitment to serving others, we established this company with a clear mission: to eradicate health hazards that disproportionately impact underserved communities.
