​Sarah Shpak, Environmental Center Educator


Sarah graduated from the University of Delaware where she studied Wildlife Conservation. As a fighting Blue Hen, her studies brought her to Ecuador and the Galapagos Islands where she discovered that the environmental world was her true calling. After graduating, she spent a year as an AmeriCorps member with the National Park service at Point Reyes National Seashore in Northern California, where her wildlife monitoring skills were put to the test as a surveyor of Elephant Seals, Spotted Owls, and Snowy Plovers. Her love for seasons and the east coast brought her back to her home state of Maryland where she spent some time working for the USFWS at Patuxent Wildlife Refuge as a Wildlife Technician. Continuing her work for public lands, she traveled to North Dakota and Montana, where she served as a Wilderness Fellow for that region. Most recently, Sarah was brought to Havre de Grace in 2013 where she reclaimed her love for the Chesapeake Bay and its values. She was an Environmental Educator at North Bay Adventure in Northeast, Maryland, where she challenged middle school students to think about how their current actions and choices impact their future, community, and environment. She continues to carry on the North Bay motto as the  Environmental Center Educator at the Maritime Museum, where she aims to inspire youth and adults through environmental experiences.
