She has studied Great Lakes Ecology aboard the R/V Lake Guardian on Lake Superior and aboard the S/V Denis Sulivan on Lake Michigan. In addition she has a strong passion for citizen science. She believes the key to stewardship is involving the community in hands-on, real-life science. Sarah has engaged the public in data-collection on the Sheboygan River Area of Concern for the past 10 years. When not working Sarah enjoys running, cycling, working out, hiking and spending time with her husband, Todd and her two children Ellison, Ethan and her yellow Labrador, Maggie. Her favorite Wisconsin animal is the Grey Fox. She finds this secretive member of the canine family fascinating because they can climb trees, either to search for prey, sleep, or to escape from predators. They have strong, hooked claws that are unique among canines. This is her 16th year working full-time at Camp Y-Koda. She enjoys her position at camp because she likes working with children and loves teaching about the natural world.
