After 30 years in enterprise systems architecture and university geosciences, David René Miller founded Headwaters & Marine Stewards® (HMS) to bring authentic coastal field science into classrooms at zero cost. Operating from Portsmouth, HMS uses a "Lean Science" model—deploying a shallow-draft skiff, aerial photogrammetry, and open-architecture water sondes to translate local Great Bay field data into free, zero-login digital labs and DIY tactile experiments for Seacoast schools. A Candid Platinum 501(c)(3) public charity, HMS bridges STEM education with municipal watershed resilience ahead of its 2027 classroom rollout.
