Instructor Fernando Martinez

Instructor Jacob Greenleaf 


Jacob Greenleaf started at Greenlake Martial Arts in 1994, training predominantly under instructors Glen Wahl and Mark Silverstein, and Sijo John Beall.  He left the school in 1998 due to time constraints and life’s complications, but continued to practice what he remembered of the system in his private life, and always felt called to return to the school one day to resume training.  That day came in early 2017 when (thanks to prodding by a dear friend) Jacob bought a 10-class punch card just to “freshen up his skills,” and found thereafter that he could not stop coming back. Though rusty, the Tsun Jo ® system was still somewhat in his bones, and restarting training was like rekindling a great romance.  He means to train in Tsun Jo ® for the rest of his life.   Jacob is a Certified Instructor and self defense specialist under Tsun Jo® System Director Matthew Soule.


Jacob was born in Seattle in 1975, and grew up in the neighborhood, on 83rd and Roosevelt.  He spent a few adolescent years as a street kid, eventually finding his way back to straight life thanks to a loving father and some lucky breaks.  These days, he spends his non-training time working as an infrastructure engineer for a major local coffee company, playing music (anything acoustic with strings and frets), reading, cooking, and raising two wonderful kids half time.


Jacob likes to focus on the geometry of Tsun Jo ® as a means to better understanding martial arts generally, and upon the minutiae of the movements, as sometimes vanishingly small details make a world of difference to practice.  Jacob teaches the Thursday evening fundamentals adult class, and fills in where needed at other times, but can always be found at the evening adult classes, just about every day.
