The Korean Academy of Taekwondo is one of Colorado's Taekwondo and martial arts schools. The school was founded in February 1980 by Grandmaster Jae Kyu Chung. The school has produced numerous tournament champions  and has trained thousands of students throughout the years. They have also contributed several non-peer reviewed articles on the physics and mechanics of martial arts. The school has several locations in Colorado and has at times had locations in Texas and Baghdad, Iraq.
Grandmaster Chung's first school was in Aurora, Colorado, later moving to the Mississippi address. In the mid nineties, he transferred control over the Aurora school to his student, Master Ghassan Timani. Master Ghassan continued to exercise control over the Korean Academy and Master Chung sold all three of the schools, returning to Korea to pursue a career in politics. While in Korea, he served as the head of security for Kim De Jung, the former president of South Korea. Master Ghassan is the highest student of Grandmaster Chung in the world. After moving and expanding several times, the Aurora location is now in a facility on E. Mississippi built especially for Taekwondo by Master Ghassan.
In 2004, the Korean Academy saw the addition of Master Bill Pottle, one of the Korean Academy’s highest ranking students. After getting his black belt from the Korean Academy, Master Bill trained at Cornell University and the University of Pennsylvania where he was pursuing academic and professional interests.
Master Ghassan has now passed the school on to Master Pottle, who has overseen its continued success and growth. Since then, the Korean Academy of Taekwondo has continued to expand. Master Emelio Tio moved to Texas where he opened an independent KAT Texas branch. Master Pottle has also opened a KAT South Branch in Colorado.
Recently, the school has moved towards a much more scientific basis of training. They were featured in an article by the Korean Embassy on the modernization of the art. In 2005 they held their 100th promotion test  and 
In 2010, the school expanded a branch to Loveland, CO. Three instructors were featured in the national press about older students training in Taekwondo.
Numerous students and instructors have served on the Colorado State Taekwondo Association board. Currently this includes Master LaRon Younger as marketing director and Instructor Sir Salonis as athlete Representative.
The school was founded by Grandmaster Jae Kyu Chung, the first head instructor. Before coming to America, Grandmaster Chung was influential in Brazilian Taekwondo. In 1987, he coached the US Team to a near sweep in the Pan-AM Games  In his March, 1997 Farewell Address, outgoing United States Taekwondo Union President Hwa Chong thanked Grandmaster Chung for his role in helping to get Taekwondo to be a full medal sport in the Olympics.
Master Ghassan Timani has been a major player in Colorado Taekwondo since before he took over the school in 1995. He has served over a decade as an officer of the Colorado State Taekwondo Association, currently as Treasurer. He has been quoted in a number of print articles on martial arts  and  In 2000, he was selected as an official delegate to attend the Olympics for the USA. In 2004 Master Ghassan Timani transferred the school to Master Bill Pottle
Master Bill Pottle joined the school in 1992. In 1997, he left to attend Cornell University, where he is mentioned several times in their club history  He was also captain of the first ever Ivy/Northeast Collegiate Taekwondo League All Star Team.
