“I love being a student at Trinity because of the wonderful faculty members. Each individual and unique class I take is paired with an equally individual and unique teacher. The passion they have for their subjects influences me every day. They inspire me to work harder and show me the beauty in all areas of study. Their enthusiasm for learning is contagious, and I am grateful for every single one of them!”
