Mark Boyce

Mark Boyce

Board Vice President

Born of the countless hours spent along Menomonee River Parkway as a kid, one profound aspect of Mark’s life-long, nature-loving sensibility has been his relationship with water, especially the waters of Wisconsin. He’s on the water, in the water, at the water’s edge or dreaming about his next interaction with lakes and rivers, always.
With a bachelor’s degree in Fine Arts from the UWM, Mark’s creative aesthetic is woven into his relationship with the natural world. His career in creative, design and marketing spans local to Fortune 500 companies. With his creative counsel, Mark helped us rebrand the Milwaukee Riverkeeper.
Mark has been with the Milwaukee Riverkeeper for the past decade and brings his hands-on passion for the Milwaukee River basin. Mark has traveled waterways across North America, from Costa Rica to Canada, strengthening his understanding of the role water plays in all our lives. Informed by countless interactions with those who apply themselves unselfishly to improving our environment, Mark looks forward to the positive role he can play here at home with the Milwaukee Riverkeeper.

Patti McNair

Patti McNair

A resource she and her family appreciate tremendously from their home along the Milwaukee River. Trained as an architect, she has spent her career exploring the human experience in the built environment and finds the intersection of indoor and outdoor spaces to be one of the most interesting juxtapositions in design. Patti is currently the Director of Design with Stirling Furnishings following roles with Trek Bicycle Company, Harley-Davidson Motor Company, and HGA Architects. She earned a Master’s degree in Architecture from the University of Wisconsin – Milwaukee, following a Bachelor’s degree in Economics from Whitman College.
