Come see us at the Earth Educators' Rendezvous, July 20-23, 2026, at the University of South Carolina in Columbia, South Carolina.

Team

The Emriver team is a bunch of smart, talented, and fun-loving folks from diverse backgrounds who are passionate about rivers, the outdoors, and science. We each have our specialties but we all do a little of everything every day, including learning new things and acquiring new skills. When we are not making the best stream tables in the world, we are artists, musicians, birders, runners, 
and swimmers.
