Hi! I’m Marc, a full-time chemistry teacher with over 20 years of experience teaching both high school chemistry and AP Chemistry. I’m also a current AP Exam Reader for the College Board, which gives me deep insight into how students are evaluated on the AP exam—and how to help them succeed.

Whether you're working through mole conversions, equilibrium, thermodynamics, or lab-based analysis, I specialize in making complex concepts clear and manageable. I’ve helped students raise their scores, write stronger lab reports, and approach their exams with confidence.

In addition to teaching, I’ve designed AP-aligned assessments, led professional learning communities for science educators, and supported students of all backgrounds in mastering chemistry—not just memorizing it.

I offer:

High school general chemistry support

Expert AP Chemistry tutoring

Introductory college chemistry (Gen Chem I & II)

Lab coaching and FRQ writing strategies

Sessions are personalized, targeted, and grounded in what actually helps students learn and retain. Whether you need long-term support or targeted exam prep, I’m here to help make chemistry more understandable—and a lot less stressful.
