"For a topic that is traditionally seen as complex and confusing, he managed to deliver his lessons in a simple to understand manner and gave real world examples to help the students better relate new concepts whenever applicable." ECON 201: Principles of Microeconomics (Spring, 2026)

"Was extremely knowledgeable about the course material and explained concepts in a way that made them easy to understand. The overall structure of the class was very well organized, and assignments and expectations were communicated clearly. I really appreciated how approachable and helpful they were whenever students had questions. Overall, this was a very positive learning experience." ECON 201: Principles of Microeconomics (Spring, 2026)

"The professor is patient in explaining the material when students don't see the logic of the problem. I've seen it firsthand when other students or I ask how we get that answer, and he would walk step by step and explain the reasoning behind each step. I enjoyed every class, and this is why I didn't miss it. I found it difficult at first because I didn't understand the problems or the formulas, but with Professor Sullivan, he made it feasible and learnable; this is why I think his teaching style has made me like math. It's complicated, but I'm intrigued to learn it; it depends on the professor and their teaching style. Thank you, Professor Sullivan!" ECON 315: Intermediate Business Microeconomics (Spring, 2026)

"He always brought good energy to class. This professor always double checked if we understood the material and provided different ways related to us to help understand the material." ECON 202: Principles of Macroeconomics (Fall, 2025)
