Teaching since:

Hi, I'm Sean! I have always loved helping people realize their potential and have mentored, tutored, and taught in many contexts.

I teach educational skills that I learned during my studies at Harvard College and Berkeley Law School, and test taking skills that I learned earning very competitive scores on the SAT, SAT II, APs, the LSAT, and the GRE. While at Harvard, I also tutored students in sociology, statistics, and writing.

I also teach athletic skills I gained rock climbing for the past decade and competing as a national finalist on NBC's American Ninja Warrior. I have taught countless children and adults climbing and ninja related skills as an instructor at gyms around the country, and at Primal Fitness here in DC.

I look forward to working with you to help you realize your potential!

Parkour · In studio

Sean is by far one of the most enthusiastic and naturally talented parkour instructors. He has taught me many movement-based skills in parkour/ninja warrior gyms as well as outdoors. He is great at gauging your skill level and helping you improve in precise and consistent ways. I have also seen Sean work with young kids at competitions and workshops. Kids love his enthusiasm and goofiness. It's like he never gets tired, which is exactly the quality you need to work with young kids!

Thank you, Sean!
