Kelly Thayer, Deputy Director

As deputy director, Kelly works to grow FLOW’s reach, revenue, programs, and partnerships. Kelly has worked with FLOW since 2014, initially as a communications consultant helping to coordinate and support FLOW’s involvement in the Oil & Water Don’t Mix campaign to shut down the aging, cracked, and encrusted Line 5 oil pipelines in the open waters of the Mackinac Straits, where Lake Michigan and Lake Huron meet. Kelly’s experience includes research, writing, and organizing communities. His leadership skills include working with local, state, and national environmental campaigns. He served as volunteer co-chair of successful election campaigns to launch a countywide public bus transit system in 2006 and renew its funding by a 3-1 margin in 2011 in Benzie County. Kelly also helped to build and co-direct state and local coalitions to advance people-centered transportation policies and projects in Michigan from 1998-2005 while working with the Michigan Land Use Institute. For more than a decade thereafter, Kelly worked as a consultant at The Resource for Great Programs, a national firm working to strengthen foundations that support, and nonprofit law firms that provide, free civil legal aid to people in poverty across the nation. Kelly volunteered in the U.S. Peace Corps in Tanzania, East Africa, where he and his wife Carolyn served as village-based volunteers for two years. He earned a Master of Arts in Journalism and a Bachelor of Arts in English Literature from the University of Michigan.

Diane Dupuis, Development Director

After earning a BA in French and English from Kalamazoo College, Diane embarked on a career in publishing that culminated in a position as Publisher of Visible Ink Press. Pivoting to the nonprofit sector, she spent ten years serving Interlochen Center for the Arts in communications and fund-development roles before fundraising for two land conservancies in Michigan, and for the Ann Arbor Art Center. Past volunteer affiliations include Pathfinder School, Parallel 45 Theatre, Michigan Writers, and Washtenaw Literacy; she now serves as Vice Chair of Michigan Audubon.

Calli Crow, Development Specialist

Calli comes to FLOW as a true believer in the power and magic of intentional volunteer engagement to advance missions, generate community support, and create advocates for the cause. She passionately supports FLOW’s mission to protect the Great Lakes and brings her experience in nonprofit fundraising, events, and volunteer engagement to the fund-development team. 

A graduate of Grand Valley State University’s School of Public, Nonprofit, and Health Administration, Calli holds a Master of Philanthropy and Nonprofit Leadership and is a Certified Volunteer Administrator. She comes to FLOW from Grand Rapids, Michigan, where she most recently worked for the award-winning Kent District Library system as a volunteer engagement specialist. A volunteer herself, while in Grand Rapids, she gave her time to the boards of the Greater Grand Rapids Bicycle Coalition and Volunteer Management Association of West Michigan.

“I was born and raised in Southern Illinois near the Indiana and Kentucky borders. My Aunt Patti and Uncle Ron moved to Michigan when I was a kid, and I got to visit one summer. I’ll never forget my first glimpse of Lake Michigan!,” Calli recalls. “I thought, ‘It’s the ocean! But it doesn’t sting my eyes!’ I eventually came back up to visit my cousin Angie on the campus of Western Michigan University in Kalamazoo and mostly have been in Michigan ever since.”

Water has long been her happy place.

As for my favorite place in Michigan, growing up on the Mighty Wabash, I’ve always been a river person, and kayaking and river floats are my absolute favorite way to spend a day. My favorite river to float in Michigan so far is the Pine in the Manistee National Forest. I’m always blown away by the beauty of the trees and wildlife and clear flowing water. And this may be odd to native Michiganders, but the joy of a sandy bank is never lost on me! Southern Illinois is a muddy, mucky place where water meets land. Hooray for Michigan!”

Calli’s fun fact: She once rode her bike from Grand Rapids to Chicago to support alternative transportation by participating in the Climate Ride. “We traveled over 300 miles in four days!”

Jacob Wheeler, Communications Coordinator

Jacob edits and publishes the Glen Arbor Sun, a seasonal, biweekly newspaper that celebrates and tells stories about Leelanau County’s unique characters and places: he founded the Sun when he was 18, partly as a way to pay for his studies at the University of Michigan. He also teaches journalism and advises the White Pine Press student newspaper staff at Northwestern Michigan College in Traverse City.

Born in Denmark and raised in rural Leelanau County, Jacob holds dual citizenship and (on a good day) speaks four languages. On cold, grey winter days, he sometimes dreams of Guatemala, where he spent his mid-20s, living in a Mayan highland village, learning Spanish, hiking volcanoes, and writing a book, Between Light and Shadow (University of Nebraska Press, 2011), about the country’s child adoption industry.

Jacob’s favorite ways to cherish the Great Lakes include swimming (9 months a year!) in Lake Michigan’s holy waters or running or biking along her shoreline. The concept of the Public Trust—as policy, as a community, and as a spiritual rallying cry—resonates deeply with him.

Nayt Boyt, Operations Manager

Nayt Boyt grew up in Michigan and is most at ease in nature. From collecting frogs in his backyard to hiking all of the Sleeping Bear trails, he has always enjoyed being competitive and being outdoors. Over the years, he frequently went on camping and backpacking trips. In 2014, he thru-hiked the Appalachian Trail, and in 2015, he thru-hiked the Superior Hiking Trail, a portion of the North Country Trail. He has since hiked several portions of the North Country Trail in Michigan and plans to complete the Grand Traverse NCT 100-mile challenge this year.

It is only logical that Nayt finds himself among those at FLOW, working every day to protect the natural resources that are so important to all of us. Nayt has a bachelor’s degree in creative writing from Western Michigan University, where he was a member of Sigma Tau Delta and of the Lee Honor’s College.
