Who We Are

Dedicated to Enhancing STEM Learning for all Students and Schools

TeachSTEMCS is a mission-driven education services company committed to bridging the gap in STEM and computer science learning for K–12 and College students. We offer bilingual online tutoring in English and Spanish, making STEM subjects more accessible to diverse learners. Our tutors are experienced, culturally responsive educators who personalize support for each student’s needs—whether they’re catching up or striving to excel. By targeting schools with established STEM or CS programs, we aim to reinforce and enhance what students are already learning in the classroom.

As we grow, our vision includes supporting teachers through professional development, curriculum coaching, and digital resources designed for real classrooms. We believe that empowering educators is key to transforming education from the ground up. TeachSTEMCS was created to provide fast, effective academic support while also laying the foundation for long-term impact through teacher training and scalable instructional content. We’re here to help students thrive, teachers grow, and schools strengthen their STEM education outcomes for a diverse range of learners.
