Our History

What began as a group of dedicated volunteers in 1998 has grown into a respected regional leader in watershed restoration and community engagement.

Past

In 2000, MRWA became a registered 501(c)(3) nonprofit organization.

With early support from the Wege Foundation and the Great Lakes Fishery Trust, MRWA hired its first full-time staff, laying the foundation for long-term impact.

Over the years, MRWA has completed hundreds of projects, both large and small — from educational and community engagement efforts like stream sampling and the annual Trash Bash, to conservation and restoration work such as tree plantings, rain gardens, bank stabilization, and dam removals.

All of this work advances the Muskegon River Watershed Management Plan, first approved in 2002.

Present

MRWA has a professional staff of four working in partnership with hundreds of donors, volunteers, and partnering organizations.

Together, we are strategically advancing the Watershed Management Plan to conserve and restore the watershed.

Our headquarters are hosted by Ferris State University, and we continue to build a network of state and federal agencies, local governments, corporations, and institutions of higher education working to sustain the Muskegon River.

Future

At MRWA, our passion is making connections. Those connections with people and place are the key to our impactful, place-based restoration and conservation projects. We value affirmation, intentional action, holistic thinking, and impactful results.

Our guarantee to you is that our work will have measurable ecological and community benefit, and that the community both informs and learns from our projects.

We continue to update and focus our planning and projects for maximum positive impact, and we are actively working to build organizational and community capacity to do more good work.

Paul Haan

Executive Director

Paul Haan is dedicated to building community, protecting the environment, and preserving human health. With more than thirty years of experience building powerful communities, promoting human health, and restoring the environment, Paul is now committed to protecting, improving, and preserving quality of life in the Muskegon River watershed as MRWA’s Executive Director.

Paul grew up in the Hudson Valley of New York and was inspired at a young age by the environmental activism of Pete Seeger and those who built community as they restored the historic Clearwater sloop and brought the Hudson River back from the brink.

From there, he relocated to west Michigan to attend Calvin College where he obtained his BA in communications and philosophy. After college, he worked for and lead a number of nonprofit organizations dedicated to community organizing, community development, and environmental health. He was the founding Executive Director of the Healthy Homes Coalition of West Michigan, where he served for fourteen years. Most recently, he worked in the City of Grand Rapids Community Development Department, an invaluable experience that taught him the inner workings of government.

Paul is rarely found indoors. He is an avid gardener (his veggie garden is nearly 1,500 square feet!), a serious hiker (Appalachian Trail thru-hiker in 2000), and newly addicted fly fisherman frequently found floating the Muskegon year-round. Paul is married to Julie Nietling. They live in Grand Rapids in a 115-year-old home Paul restored, complete with a native prairie in the front yard. They have two children, Benjamin and Abbey.
