ABOUT EPN

Ohio is home to thousands of environmental professionals working every day to make the world a better place. The Environmental Professionals Network (EPN) is a service of the School of Environment and Natural Resources that connects and grows environmental professionals in-person and online. 

Participants in the Environmental Professionals Network can access many online services and are linked to thousands of professionals in Ohio and beyond. Professionals are thus connected in a "community" of people who share their passion for our world and its environment, natural resources, people, and communities -- local to global. The EPN will help you grow professionally and be more effective in your job, and be inspired about your career.

Networks create pathways for solutions to arise. Consistent, open, and diverse relationships designed to build and facilitate trust, deepen knowledge, and build a shared understanding of complex issues are necessary for Ohio, our region, nation, and planet to rise above our individual and collective challenges. Read More >>
