Emmy Kriehn – Board Member

Emmy joined the board of directors in 2023. She has a master’s in landscape architecture from the Pennsylvania State University and an undergraduate degree in liberal arts from St. John’s College in Annapolis, Maryland.

She fell in love with Lake Wingra right from the start, and learning about life under the waves always makes her day. Emmy’s profession is firmly rooted on land (landscape design and planning) and she adores playing in the dirt and watching native plants at work. But while plants are great, she believes that water and the health of our water bodies is the connector that brings us all together. In her free time, Emmy enjoys long runs around Lake Wingra, strong cups of black tea, good books, and watching her cats as they watch birds.
