Mr. Doug Farmer

Mr Doug started studying Taekwondo in 2007 with his daughters at Han Lee Taekwondo in Castle Rock, CO as part of the after school enrichment program. He started assisting in classes shortly before earning his black belt alongside his daughter (one of the proudest moments in his life) in 2010. He officially became an instructor in 2011.

Mr Doug believes there is a big difference between those who are martial artists and those who do martial arts. He strives to be the former and expects the same from his students. One of Mr Doug’s joys in life is seeing his students succeed and earn their black belt. He is passionate about all forms of martial art and loves the dual challenge of mind and body that comes from its practice.

When not doing Taekwondo, Mr Doug works as a software development manager for a “big four” tech company, skis in the winter, hikes in the summer, and listens to and attempts to play live music. Most importantly, his greatest joy in life is spending quality time with his amazing girlfriend, daughters, and their families.
