Ricky KJN started training at Kuk Sool Won of South Austin under KJN Dewain Perry. After a lot of hard work and dedication he promoted to first-degree black belt in Kuk Sool Won. Even before receiving his first-degree black belt, Ricky KJN was approved to start assistant teaching as a Dahn Bo Nim (student testing for black belt). Ricky KJN became a full-time instructor after receiving the first-degree black belt title of Jo Kyo Nim and has been teaching martial arts as his full-time job ever since.

After leaving Kuk Sool Won in 2010, Ricky Kwan Jahng Nim and his wife Meghan Kwan Jahng Nim opened a school with Mu Sool Won and started training directly under Grandmaster Byung In Lee. After receiving the title of 5th degree Master under Mu Sool Won, Meghan KJN and Ricky KJN decided it was time to officially leave Mu Sool Won and together they created Next Gen Mu Sool.

Ricky KJN is a strong believer in the idea that belts are earned and never given or bought. He believes that everyone deserves to be treated equally and it shows in his teaching style. Ricky KJN understands the importance of teaching each student based on their strengths and weaknesses, and takes the time to get to know each student to help them get the most out of their training.

Meghan KJN began her training in Kuk Sool Won in 1999 and has been instructing students since 2003. She is currently a fifth-degree black belt in Next Gen Mu Sool. She has made it her goal to have Next Gen Mu Sool running smoothly, and to train her students to the best of their abilities.

Meghan KJN works well with both children and adults, and enjoys running both hard workout classes and detailed forms classes. Her favorite weapon is the staff, and she enjoys high falling and kicking techniques. Her previous instructor, Dewain KJN, encouraged her to do more than she thought she could, and not to let being a woman give her an excuse to hold back in her training. She believes strongly in this philosophy, and she and Ricky KJN encourage all students to perform to their highest potential. Martial arts is for everyone, and through concentration and hard work, you can achieve whatever goals you have set for yourself.

My interest in martial arts began when my son started taking martial arts classes. My son, five at the time, was trying different activities. Basketball and soccer hadn't held his attention. Martial arts was next on the list.

My Mu Sool Won goals are simple: keep learning and keep improving, and help others to do the same. There's no real end point for me. I like the breadth and depth of the Mu Sool Won curriculum. The self-defense techniques of Mu Sool are my favorite aspect of the training; the use and integration of throws, joint locks, pressure points, punches, and kicks is endlessly fascinating. Among the various weapons taught at Mu Sool, I have become particularly fond of the sword.

I began assisting with instruction as a Dahn Bo Nim (a black belt candidate) in 2009. I enjoy the opportunity to teach, to pass along the skills and knowledge that I've gained over the years. It's always fun to see the joy of discovery on a student's face. And, teaching is training for me too - to teach it, you must know it!

I began Kuk Sool Won training in 2006, the week I turned 5 years old. Ever since then, Ricky Kwahn Jahng Nim and Meghan Kwahn Jahng Nim together helped mentor me. They changed my life and brought me happiness with hard work and discipline. In 2010, Ricky Kwahn Jahng Nim and Meghan Kwahn Jahng Nim switched from Kuk Sool Won to Mu Sool Won. I decided to switch with them because I could tell that they were the correct instructors for me.

I reached Jo Kyo Nim (first degree black belt) in 2011, followed by Kyo Sa Nim (second degree black belt) in 2016 and Pu Sa Bum Nim in 2019. From that time on I have worked hard to become the person and instructor I am today, and am happy with how I have improved in training since I first started. My goal in Mu Sool is to help other students of any age to become better, and become the person they want to see in themselves. I also want to become as good a martial artist as I can be.



Assistant Instructor

I started Kuk Sool Won when I was 5 years old and have been doing martial arts ever since. Now I am 17 years old and have been training twelve years. When I was a Dahn Bo Nim my commitment started to slip. When I reached first degree black belt in 2011, I found what I was training for and I started getting better and better. I was training to improve myself and to help others understand what they are training for.

You don't have to be the best to be a black belt, and I have a couple of bronze medals to prove it. The important part is dedication. Ricky Kwahn Jahng Nim helped me understand dedication, so when he decided to become a part of Mu Sool Won, I didn't hesitate to follow him. Ricky Kwahn Jahng Nim helped me be the person I am today and I want to repay him by helping others in the same way.

Oscar began his experience in martial arts training in 2000 in Tae Kwon Do. After his retirement, he sought a hobby to keep fit, help him stay alert, and find community. In November 2007, Oscar began training at Kuk Sool Won of Oak Hill where he met Ricky and Meghan. He was inspired by their dedication to the arts, and after completing his contract at Kuk Sool Won, moved to Ricky and Meghan's new Mu Sool Won school in South Austin.

He was promoted to Kyo Sa Nim, or second degree black belt, in May of 2016, and greatly benefits from the physical exercise Mu Sool Won offers. Oscar is in his early 70s, and his goal is to reach third degree black belt by age 75.

He enjoys the attentiveness of the students at Mu Sool Won of South Austin, and dedicates himself to teaching younger martial artists every week. He finds his training and teaching highly rewarding and uplifting. Oscar encourages his students to strive for their maximum potential, and they reach phenomenal levels.

When I was three, my brother started to do martial arts. Watching him made me want to join as well. Therefore, when I was five I started taking classes myself. When I was a Dahn Bo Nim (black belt candidate), I started to think about quitting. When I remembered that all of the hard work was going to pay off and I was going to be a black belt soon, my mentality completely changed. What I strive to do with the younger students is to help them remember that the hard work will pay off. Four years of training passed in a snap, and I finally earned my black belt.

Since I have become a black belt, I still train with enthusiasm. I greatly enjoy the challenge of teaching others. Watching my friends promote, people I have known for years, fills me with a sense of pride. I would like to see all of the people who join Mu Sool Won promote to their next belt and beyond.

I started Kuk Sool Won in February 2010 when I was 5 years old. I have been constantly training ever since then. When Ricky SBN and Meghan SBN left Kuk Sool Won to open Mu Sool Won of South Austin I went with them.

I am motivated to keep training because Ricky SBN and Meghan SBN are great motivators and training is exciting and fun. When I saw how crisp my instructors could do a form I wanted to keep training so I could be that good. My favorite thing about Mu Sool Won is how friendly everyone is. I used to be shy and quiet, but now I can instruct and lead other students.

As a child, I always enjoyed martial arts portrayed in the movies. In my early 20s, I had opportunities to take martial arts lessons from a few different instructors. However, none of them grabbed my attention or inspired me to continue training. Little did I know that becoming a parent would reverse that mindset! My son joined Mu Sool Won of South Austin in September 2011 at age 7. After just two months, I knew that it was going to be the place for me as well. I was impressed with the way Ricky KJN and Meghan KJN held students accountable for upholding the values of the school, taught students about respect, promoted hard work to meet goals, personalized their teaching to each student, and encouraged family involvement. When my daughter turned five she also joined. We share a great love for the family we have found.

After nine years, we are still going strong with this martial arts family. My son and I are second degree black belts and my daughter is a first degree. Mu Sool Won of South Austin, now named Next Gen Mu Sool, is a part of our family. This school has taught my children and me patience, the value of hard work, the love of a challenge, and has given us a fun and creative outlet for our energies! I look forward to my future in martial arts as I continue to work toward my third degree black belt!

Colton Kyo Sa Nim is currently in charge of the Little Dragons program, and teaches our beginner and intermediate students.  He is an energetic instructor from whom the kids enjoy learning.  He is a second-degree black belt and has been a student of Ricky KJN and Meghan KJN for the past 15 years.

I have been training in Mu Sool Won since 2012. I have been training for almost 8 years with Ricky KJN and Meghan KJN. I quickly began to enjoy coming to class regularly and learned a lot about work. The road to getting my black belt took lots of dedication and time, but I stuck with it and continue to enjoy going to class.

I find teaching the future generation is very rewarding and even teaches me more about my material. Ricky KJN and Meghan KJN have always been great teachers and motivators. I love training and pushing myself with the great community we have built at Next Gen Mu Sool.
