Tanya Denckla Cobb

In 1997 I found a professional “home” at IEN for my passion for bringing people together to discover common ground and create solutions for mutual gain. Beginning as a Senior Associate, then Associate Director, I was privileged to be appointed Director in 2015. Through the years my work has covered a broad range of challenging environmental, agricultural and community issues. Now, as Director, working with a talented and collaborative team, I strive to be a servant leader while providing vision and strategic direction. As we build on IEN’s rich history to continue tackling the tough issues with integrity, our team seeks to meet the evolving needs of our times, through innovative leadership in our field and engaging stakeholders in ways that are fresh, focused, relevant and effective.

As a mediator and facilitator, I seek to help individuals and groups address complex public problems and conflicts in ways that strengthen communities rather than tear them apart. Each year I work on average on a dozen or so projects involving environment and land use, contaminated sites, community development, education, and health. I have also facilitated many difficult community conversations on topics ranging from faith and homosexuality, to education, to reparations for slavery.
