Nate T.
Nathan (goes by Nate) knows math and loves math, inside and out. He spent 15 years earning his doctorate and pursuing primary mathematics research, teaching and tutoring at the high school and college level all along the way. He’s currently serving as Adjunct Faculty at the College of DuPage and Waubonsee Community College tutoring high school students in math. However, he has taught and tutored students in places as far-flung as the University of Michigan, Duke University, UMass Amherst and the University of Miami.
With Nate, you won’t just get a tutor that knows the material in a few high school courses. You’ll get someone who …
… tutors from a place of understanding and with a growth mindset: where mistakes are a normal, and even essential, part of learning something new,
… is familiar with the whole high school curriculum: not just your student’s class, but the classes preceding it, and so can diagnose knowledge gaps and fill them with mini-lessons on the fly,
… can prep for college entrance exams including the SAT and ACT,
… knows the undergraduate mathematics curriculum and can tutor for students enrolled in dual credit or enrichment courses, and welcomes tutoring college students as well.
In his spare time, Nate likes to play table top role playing games, and is an amateur bodybuilder, although he still thinks about research questions in math from time to time too.
With Nate, your student’s math education is in the best hands!
