Calvin Student Staff

Immersive learning is central to our mission. Calvin students develop professional skills in the fields of environmental education and land management in a real-world setting when they are employed at the preserve. Our student staff members major in a variety of subjects and bring a depth of educational experience and interests to the preserve. They have a passion for learning and sharing their ideas and knowledge with whom they work. Learn more about employment opportunities for Calvin students at the Calvin Ecosystem Preserve & Native Gardens.
