Brett Harrington was born in February 2007 and started training under Sa Bom Nim Guinn in the summer of 2017. He started originally just as a fun activity to take part in after school and stay in good shape, but it quickly became a monumental part of his life as he started to progress through the ranks.

He applied for his Jo Kyo certification in November 2019 and became certified as an assistant instructor shortly after. He then started to teach classes when the other instructors were unavailable for the night. In October 2020, Brett tested for his 1st Degree Midnight Blue Belt or Cho Dan. He passed the test and kept on teaching in the Dojang when he had the opportunity to.

Brett plans to continue training and continue teaching for as long as he can and greatly values all of the lessons he has learned from his experience in both. He considers everything he has learned in the Dojang invaluable and hopes to keep learning more, so he can become a better student, instructor, and person.
