I advise students with interests in:

Biology, Environmental Studies, Science

Why you enjoy teaching Hillyer students:

At Hillyer, I get to not only work with interesting students, but get to really know them. I look forward to passing on my love of science, nature, and learning in general, as well as sharing some of the incredibly fun and rewarding experiences to which those interests have often led.
