Success Stories

Find an internship in the field you want to pursue and learn from people already in the profession. I ended up getting my first internship with the Fish and Wildlife Service the summer after my freshman year . . . My favorite class, Science and Christianity, blended my faith and my love of science. The exposure I gained to environmental law and policy has been important throughout my career.
