How We Started

Edthena was born from real-world classroom experiences. As a science teacher in St. Louis, Mo., founder and CEO Adam Geller wanted to be great for his students but there was no one in his building with science expertise. He did know someone at the local science museum, but that person could never come to his classroom.

After leaving the classroom, while working on the national strategy team of an education nonprofit, Adam started to realize that the challenges he faced as a teacher were common among most schools, districts, and teacher education programs. We know the best way to help teachers is to analyze actual classroom teaching, and it’s hard to have the right person in the right place at the right time.

In 2011, Adam was named a Kauffman Foundation Education Ventures Fellow and took the leap and start Edthena. In 2012, he joined forces with Dave Weldon, CTO, to start building the version of Edthena people know and love today.
