Our Mission
A Legacy of Hard Work and Precision
Our story began as a deeply personal endeavor. Our father arrived in America from Colombia at just 17 years old, carrying little more than a bag of clothes and an unwavering dream to build a lasting legacy. Growing up, my twin sister and I witnessed his relentless dedication firsthand, contributing to the family business from our teenage years. This instilled in us a profound understanding of hard work, grit, and the vital importance of community safety.
Built upon a foundation of faith and intergenerational strength, Cornerstone Testing Solutions was established with a singular, clear mission: to protect families and property managers throughout New York from environmental health hazards. Today, we bridge the gap between rigorous local compliance and dedicated, comprehensive care—helping our clients protect their investments and their tenants.
To provide NYC property owners with absolute clarity, integrity, and precision in environmental testing. We leverage generations of local expertise to eradicate environmental hazards, protect public health, and ensure seamless regulatory compliance.
