Our full-time educators are recent college graduates who have mastered the skills students need to succeed and are well versed with Sage’s methods, curriculum, and culture, in order to provide your students with the best tutoring experience available in the Bay Area. Having recently graduated themselves, our educators offer students help from adults they can relate to (not adults they are related to).

Aaron, Educator

Aaron Batker Pritzker graduated from Harvey Mudd College with a bachelor’s degree in physics, and continued in physics to the University of Wisconsin-Madison for part of a Ph.D. program, before deciding his more fundamental questions lay in philosophy.

He’s worked in physics to improve the efficiency of thin-film solar cells, test a new explanation for how the conductivity of a magnet changes next to a heavy metal, and simulate noise patterns in quantum computing hardware. In philosophy, his project has been to tell a story about which kinds of entities make up thoughts, feelings, emotions, and sensations, just like physicists tell a very compelling story about which kinds of entities make up everything else. Throughout his education, he’s been teaching and tutoring; his favorite part of this area of his life is discovering the way that each student learns so he can strengthen their particular skillset.
