Who are We


Stone Three Impact (S3I) is an independent nonprofit organization dedicated to empowering young minds through science, technology, engineering, and mathematics (STEM). We believe that talent, skills, and academic resilience grow through exposure and opportunity. That’s why we provide learners, especially those from underprivileged communities, with meaningful experiences in STEM - helping them discover skills and interests they may never have imagined, as well as building academic perseverance and confidence.
