Two decades of helping students tap into their reasoning skills, even under time pressure.

With over twenty years of teaching experience, Mark has helped thousands of students prepare for the GMAT, GRE, and EA through private tutoring, classes, and coaching. They also have extensive curriculum design experience—the courses they've built include Manhattan Prep's Advanced GMAT Course and GMAC's Business Fundamentals Statistics Course, and they were a senior curriculum developer throughout MPrep's transition to the Focus Edition of the GMAT.

Mark holds a B.S. in mathematics from Caltech and an M.S. in mathematics from the University of Washington. But somewhere along the path to academia, they realized their true passion was teaching—not publishing research papers only six other people would ever read 😅!

For the past fifteen years, they've been a professor of mathematics and statistics at Shoreline College, teaching all levels of college math and stats. But most of Mark's professional work is spent helping students prepare for graduate admissions tests. And yes, they still take those tests: recent scores include a GMAT 775 (Quant 90, Verbal 90, Data Insights 86) and a GRE 340 (a perfect 170 on both Quant and Verbal).

The name Deliberate Prep comes from the concept of "deliberate practice": real progress doesn't come from grinding through thousands of random practice questions, but from focused, intentional work on the right things, with regular, thoughtful review. That process looks different for everyone, which is why working with Mark isn't about following a rigid, one-size-fits-all syllabus. Instead, it's a deeply supportive, custom-tailored partnership that adapts to your strengths, learning preferences, calendar, and goals, every step of the journey.

Mark likes to create a safe, encouraging space to explore new ideas and make plenty of mistakes—which happens to be the best way to spot exactly where to grow. You'll stay genuinely challenged while building true, flexible mastery rather than relying on tricks or rote memorization. Scores rarely move in a straight line, and smart preparation plans for that: the flat weeks are where consolidation happens, and Mark is right there with you to adjust the roadmap whenever your path needs a pivot.

When not teaching, Mark loves all the stereotypical Pacific Northwest activities you'd probably guess: hiking, backpacking, paddleboarding, drinking way too much coffee, and defending the Seattle Mariners to anyone who will listen.
