Training is focused, purposeful, and grounded in respect. Through group classes and personalized instruction, our instructors take the time to understand each student’s goals, learning style, and experience level.

MEET THE TEAM

Ken O'Neil cHIEF iNSTRUCTOR

Sensei Ken’s martial arts journey began when he was eight years old. Inspired by the senseis who invested in him and by his grandfather, a military veteran and Golden Gloves boxer who supported his training and competition throughout his life, Ken sees teaching as an opportunity to pay that same support forward.

At USSD Mountain View, Sensei Ken’s philosophy is simple: family comes first. His goal is to create a dojo where every student feels welcomed, respected, and heard. Rather than expecting every student to learn the same way, he takes the time to understand each person, meet them where they are, and help them progress at their own pace.

Sensei Ken wants every student to know they are part of something when they walk through the doors of USSD Mountain View.
