"I’ve been going to the Saint Louis Zoo since I was a little kid, and the Primate House was my favorite part to go to every time. When I decided on my major and found out I needed an internship, the Saint Louis Zoo was the first place I thought of. I get to learn all about the species that they care for in the Primate House and how different each of them are. I am seeing how zoos work and how much they do for the animals and the conservation work of animals all around the world."
