Favorite place on campus: My favorite place on campus is the old Speaking Center room in Asbury. I used to spend so much time there doing homework, studying for finals, and tutoring my peers. It always felt like a safe and comfortable space for me.
Favorite place to eat in Greencastle: Tokyo Steakhouse. It is a gem.
Favorite DePauw tradition: Walking under the arch your incoming and graduating years. It brings you full circle. You walk under it alone for the first time, and you walk under it with your friends the last.
Advice to students considering DePauw: As you get to know DePauw, let DePauw know you. Allow this place to envision your growth, power, and care. Work together to meet in the middle, as this could be your new home for years to come.
