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.
