About NGSNavigators

NGSNavigators is part of the Margaret O'Sullivan STEM Foundation, a nonprofit formed in late 2020 to continue the work and legacy of Margaret O'Sullivan.

NGS Navigators was founded by Margaret O’Sullivan in 2018. Her passion for teaching science led her to develop a professional development program that is efficient, effective, and engaging for K-12 science educators. She soon became an active voice in the NGSS community and began a widely popular podcast and designing a course to help guide teachers in their journey to create their own effective NGSS lessons and units. 

Margaret passed away in March 2020 following a courageous battle with cancer. The outpouring of love and support we saw from science educators following her tragic passing confirmed to us the immense impact that her work had on this community.

Inspired by her legacy, we are continuing the work that Margaret started. We have reorganized NGSNavigators into a nonprofit in order to maximize our commitment to providing content and programs that best serve this amazing community.
