About Our School

Welcome to Moorimgoong's Website!

Moorimgoong is a Traditional and Mixed Martial Arts Academy (Dojang) that places great emphasis on retaining the fundamental mindsets of martial arts such as discipline, respect, and integrity. Our academy focuses on two distinct aspects of martial arts: practicality and performance.

We are located in the heart of LA between Miracle Mile, Downtown LA, Koreatown, and Mid-City.

Moorimdo is a Hybrid Martial Arts that stems from Kung Fu (Shaolin Long Fist, Baguazhang, and Tang Lang Quan), Tang Soo Do (Korean Karate), Karate, and Tae Kwon Do. MooriMMA is Moorimgoong's Mixed Martial Arts Program that teaches different striking and submission grappling based Martial Art styles from Moorimdo, Kickboxing, Muay Thai, Brazilian Jiu Jitsu, Judo, Tae Kwon Do, Karate, Kung Fu, and more. MooriMMA is unique for its systematized rank system that allows people of any skill set to train at a pace relative to their individual goals and attributes.

Moorimgoong's Founder, Great Grandmaster Yong Moon, opened his first school in Busan, South Korea in 1968. After many years of success, he decided to come to America. His first school was located in New Orleans, Louisiana where he was a local celebrity by the name of “Master Moon." Eventually, he headed west, moving to LA and started another dojang. We have been here in Los Angeles ever since for 29 years. As a 10th degree black belt in Kung Fu and 9th degree black belt in Taekwondo, he decided to create his own traditional martial arts style: Moorimdo.

David Moon

CEO/Head Instructor

David S. Moon is the Chief Executive Officer and Head Instructor at Moorimgoong Martial Arts. He is a 6th degree black belt in Moorimdo under Great Grandmaster Yong Moon and currently runs all classes and operations at the academy. He has trained in many other styles including Kung Fu, Kickboxing, Brazilian Jiu Jitsu, Muay Thai, and Taekwondo to name a few. He is the founder of Moorimgoong’s Mixed Martial Arts Program: MooriMMA, which teaches MMA with a systematized curriculum and belt system.

Moon is an LA native as he was born and raised in Los Angeles, California. He attended Wilton Place Elementary, John Burroughs Middle School, Math and Science College Preparatory, and the University of California, Los Angeles with a major in Sociology and a minor in Film. In his childhood days, he competed in golf and was one of the top ranked juniors in the world. His wide array of knowledge and skills at a young age has translated into his exceptional teaching skills to people of all ages and levels.


Great Grandmaster Yong Moon was born in Hapcheon, South Korea, and began training at an early age as he was born into a martial arts household. He first began training in Tang Soo Do, a very popular style in his region. After many years of practicing Tang Soo Do, he then learned Classical Kung Fu under Master Kang Gum Bang in Busan, South Korea. Master Kang Gum Bang was one of the three Chinese historic masters who emigrated to South Korea during the Communist Revolution in China.

After many years of training under the famous Master Kang Gum Bang, Great Grandmaster Moon decided to start his own school, teaching a hybrid form of both Korean and Chinese martial arts. This fusion of styles is analogous to Bruce Lee’s Jeet Kune Do, which Bruce based it off of his previous training in Kung Fu and Wing Chun.

Great Grandmaster founded The World Martial Arts Federation in 1968, and started in Busan, South Korea. In 1979, he immigrated to the United States and started a school in New Orleans, Louisiana. He quickly rose to fame as “Master Moon” in Louisiana, receiving a plethora of media attention through his martial arts. In 1992, Great Grandmaster Moon moved to Los Angeles, California, started a school, and has been in Los Angeles ever since.

  • This dojo is by far one of the most welcoming places and has very nice instructors everyone makes the environment safe for all including students, parents, and the neighborhood. This is a great place to bring your kids to for they are able to learn valuable skills in martial arts, patients, technique, and respect. Overall a great positive space with lots of good vibes and they have been able to maintain all of the regulations for health safety.

  • If you are in the la area and want to train for self defense, fitness, health, or just to pick up a new hobby, I highly recommend this place! I started attending Moorimgoong back in October 2019 when David launched the MMA program. After a few months of training, I feel a lot more confident in walking around the streets in LA. I feel as if I found another family here at Moorimgoong. Super glad that I chose this place as my martial arts gym!

  • My eldest child and oldest son, Daniel was – at best – mostly C’s and an occasional B in school. He’s been doing Moorimdo for about 8 months now. After joining Moorimgoong, he has been receiving all A's in his assignments and exams after just three months of attending Moorimgoong. The instructors changed my son's character from a kid who only played games to a goal oriented individual who lives to his fullest and strives for excellence. The money, time, and effort invested has already paid off. I can't even imagine where he will be in a few years from now. We thank Moorimgoong everyday within our household on what they've done for our family. Yesterday, I went on to sign up my two other kids. Our family will be with Moorimgoong for many many years to come.
