I began teaching in 2008 at the Queen Anne Community Center and continue to teach there. I graduated from the University of Washington and have lived in Seattle since 1997. I have trained in boxing and am a 12 time Grand Champion fighter.

4th Degree Black Belt

Mr. Greivell

I have been practicing Tae Kwon Do since 1999, I first started when I was 8 years old. I got my first black belt in 2005. In 2011 while working a night shift I found myself teaching many of the noon classes offered at the Renton studio in Master Henkel’s absence. After returning to a normal work schedule years later, I continued to teach and to this day I teach many of the weekend classes offered at the Renton studio. Seeing students succeed is my biggest enjoyment of teaching. I always strive to teach a fun and unique class, one that gets students out of the same old normal routine. I am also a substitute teacher for the Renton studio’s Cage Fitness classes. Outside of Tae Kwon Do I enjoy hiking, traveling and furthering my college education.


3rd Degree Black Belt

Ms. Tsui

I grew up in Hong Kong and moved to United State to study in college. I earned my Accounting degree at University of Washington in 1993. Since then, I have been working as a business consultant and a CPA.  In 2010, my son and I started practicing TKD under Master Ahn at Queen Anne Community Center. I am very excited about the teaching opportunity at Rainier Valley Tae Kwon Studio, as I believe teaching is the best way to learn and improve. My husband John and I have four children (2 boys, 1 girl and 1 dog). One interesting fact about me:  I have a twin sister and we look very much alike, but we are not sure, if we are identical or fraternal twins. 


5th Degree Black Belt

Master Dacuan

I have studied Tae Kwon Do since 1996 under Master Henkel, 7th Degree, in Renton, WA.  I also teach at Kim's Tae Kwon Do Burien. I graduated from the University of Washington with my Bachelor's degree in 2012, and I earned my Master's degree through the Boston Teacher Residency in 2013. Outside of Tae Kwon Do, I am a public school teacher. I believe that learning (both in and out of the studio) can empower and enrich anyone's life. When I am not practicing Tae Kwon Do, I like to read, watch movies and try new food.

Mr. Jury

I am a third degree black belt and have been studying Tae Kwon Do with 7th Degree Black Belt Master Josh Henkel at Kim's Tae Kwon Do Renton since 2007. I completed the Instructor Certification program when I was a first degree black belt and started instructing when I was a black stripe. I enjoy teaching and competing in Tae Kwon Do tournaments. Other interests include reading books, playing board games, collecting and playing with Magic the Gathering and Pokemon cards.
