    My Callison

    Hello! My name is My Callison and I’m the owner and Head Master of KSMY Martial Arts. I strive to develop a personal and constructive relationship with each and every one of my students. I hope to inspire individuals to take a positive and active approach in life. I plan to be with my students every step of the way to help them reach their individual goals. Martial Arts is not just a hobby for me, it is my life! I hope to be able to share my love and appreciation for marital arts with you!

    Master My Callison, Gwan Jang Nim, has been dedicated to Hapkido for 30 years. She is currently a Fifth Degree Black Belt under the Korea Kuk Sool Association, the World Kido Federation, and the Han Min Jok Hapkido Association.

    My Gwan Jang Nim began her training under Chiefmaster Chun Duk Lee in 1993 at the Stockton Kuk Sool Won school. She was awarded the rank of First Degree Black Belt in December of 1998 by 10th Degree Grandmaster In Sun Seo. She served as an assistant instructor at the Stockton Kuk Sool Won school.

    Beginning in 2002, Master My has made several trips to South Korea to train with Chiefmaster Lee at the Korea Kuk Sool Headquarters in Busan, South Korea. Master My served as the Head Instructor for the Korea Kuk Sool Headquarters during her many trips to South Korea.

    In addition to her commitment to martial arts, My Gwan Jang Nim also values her continued education. After graduating with a Bachelors Degree in Social Science and Interdisciplinary Studies, she completed the Teacher Preparation Program at the California State University of Sacramento and obtained a professional single subject teaching credential in 2005. Master My taught World History and Psychology in the Elk Grove Unified School District.

    In 2009, Master My moved to South Korea to train for her Fourth Degree Black Belt. During this time, she established strong, personal, and professional ties with Kuk Sool masters from all over South Korea.

    In 2011, Master My established the KSMY Martial Arts dojang in the Sacramento area. This was a dream come true for Master My given she can now combine her passion for teaching with her love of martial arts. In 2023, Master My obtained her 6th Dan blackbelt. She currently trains under Chiefmaster Steve Seo, International Director of the World Kido Federation.

    Master My prides herself on having an in-depth knowledge of teaching students of various abilities and levels, as she has extensive experience instructing in both the classroom and in martial arts dojangs. On behalf of Master My and our KSMY Martial Arts family, we hope to make you a part of our team!

  • Assistant Instructor
    Cameron Ho

    I began training with Master My at the age of eight, along with my brother Caleb Ho, and was immediately passionate about learning Hapkido/Kuk Sool. I’m currently a 2nd Degree Blackbelt.

    Beginning my journey into the lifestyle of a martial artist, I’ve always had a respect for Master My and her skills, as well as for other higher ranked students. My brother and I caught on quick about the school’s expectations teaching me discipline, while in the presence of others. With the influence of my teachers, family, and other students, my martial arts skills had advanced at a significantly fast rate.

    Currently, as well as every day, I push to improve myself as a martial artist, a person, and an instructor. I focus on helping students’ skills grow by constructing my own teaching style to make my instruction more natural.

    Continuing Kuk Sool in the future, I want to increase my martial arts skills, as well as my teaching skills, for I still have much to learn from Master My. I wish to expand my knowledge of Kuk Sool, as it will help me understand more about myself and the world around me.

    Training at KSMY Martial Arts under Master My’s teaching, I have practiced respect for others, responsibility as an instructor, and discipline for the martial arts lifestyle.

  • Assistant Instructor
    Caleb Ho

    I joined KSMY Martial Arts as a curious five year old. I soon found interest in the art of Kuk Sool and wanted to pursue it further.

    When I was younger, KSMY helped me to become more focused, because I joked around in class. My brother Cameron and I influenced each other, since we always wanted to help each other progress as martial artists. As I got older, I started to understand the concepts of martial arts better, and my skills progressed.

    As a 2nd degree black belt, Master My continues to be my influence because I look up to her as my instructor. I start to influence other students under me by giving them my knowledge and experience. I am focusing on working with others, and breaking down what I know to understand why I do it.

    Moving forward, I influence myself by trying to understand the deeper meaning of martial arts. I would like to influence other students as I understand more, so I can teach others with more knowledge and experience. Becoming higher up in the ranks, I would like to discipline myself to be more serious in my martial arts training.

    As a martial artist, and while training at KSMY, I have learned self discipline, respect, integrity, responsibility and humility. Master My encourages me to pursue farther as a person, under the lifestyle as a martial artist.

    I have been training in Hapkido since the age of 8 years old. I help out with the Youth and Adults classes and the Sparring classes. I am currently a 2nd degree blackbelt and I’m hoping to go beyond and someday open up my own dojang.

    I enjoy hobbies such as martial arts tricking, soccer, and programming. KSMY is like a family to me and they have helped me so much in life and improving my everyday with my love for martial arts.

    I really hope you can make it out and be a part of this family. Hope to see you soon!

    Derrick Rogers

    Hello!  My name is Derrick Rogers. I have prior experience in Judo and Hanmudo. I began my journey in Hapkido when I moved to Sacramento and was looking to get back into martial arts after many years of inactivity. I am currently a 1st degree blackbelt.

    Under Master My’s instruction, I have regained my passion for martial arts. I have become more confident as a person and I have noticed a vast improvement in my coordination.  Master My has encouraged myself and others to try our best in all situations.

    KSMY has been a positive environment where I have been able to continue to grow as a student as well as a leader. I enjoy training alongside my KSMY family as we encourage and learn from each other.

    Outside the dojang, I enjoy watching pro wrestling, writing poetry, and bowling. I look forward to meeting and working with you soon!

    David Morrison

    Hi!  My name is David Morrison; by day, I’m a computer scientist and software engineer, and the rest of the time I’m a parent, photographer, storyteller, and of course — martial artist.

    I joined KSMY Martial Arts in 2016.  At the time the studio was a few blocks from our house, and it was a great way for me to stay in shape and develop an awareness of my body that I’ve never had before.  I’ve since moved a bit further away, but still train with Master My and the other students at KSMY every chance I get!

    Master My is a tremendous person, instructor, and friend, and I feel very honored to be pursuing my black belt under her supervision.  As a senior leader at KSMY, I enjoy the opportunity to give back to the studio, and help pass on what I’ve learned to the other adults, juniors, and tiny tigers who train in our family!

    Colin Scott

    I became interested in Martial Arts while living in Cambodia at around five and a half years old. When my family moved back to the United States at the age of 6, we began searching for a martial arts school.

    After visiting a few schools and finally landing at KSMY, I instantly felt I had found the right school.  Master My made me feel part of a larger family and my passion for Kuk Sool began to grow everyday. Ma’am My’s passion for Kuk Sool has motivated my passion and has encouraged me to grow as a Martial Artist and as a person. While at KSMY, my understanding of respect, discipline and humility has grown, which has carried over into my home and school life. I have earned Leadership Awards and achieved top academic acknowledgements from my school. I also understand how hard my parents work to teach and guide me.

    I practice hard at KSMY and at home as well. Ma’am My has allowed me to help with teaching our Tiny Tigers, which I enjoy very much. It helps remind me of where I started and how much everyone helped me. Now I have been given the opportunity to pass it on.

    In July of 2018, I was allowed to attend the World Haminjok Hapkido Summit. I was so honored to meet and shake hands with Grand Master In Sun Seo and Master Steve, as well as practice with other Masters from South Korea and around the world. This I will never forget as it further fueled my passion for Hapkido.

    In September of 2022, I was able to attend and compete in the World Kido Federation/Hanminjok Hapkido World Championships with many of my KSMY brothers and sisters. I was honored to have been promoted to 1st Dan during this trip in South Korea! South Korea is a beautiful country and I look forward to returning soon!

    KSMY is like a family and I’m proud to be a part of it!!!

  • Adult Leader
    Claudio Fernandez

    Hello, my name is Claudio. I am from Chile (yup that skinny country at the end of the world). I moved to Sacramento around October 2021. I contacted Master My to attend class as an observer … 60 minutes later I signed up. Today, I proudly hold a Red Belt at KSMY Martial Arts and I’m working my path to the 1st-degree black belt under the guidance of Master My and the Instructors/Leaders of our Dojang.

    I always liked martial arts; I grew up watching old kung fu/martial arts movies. However, Kuk Sool Mu Ye Hapkido has been the best decision ever. The broad spectrum of techniques you learn here allows you to be ready for multiple self-defence situations, including falling and tumbling.

    I would encourage any adult considering martial arts to join us. Hapkido practice at KSMY Martial Arts has a major contribution to mental health due to stress relief, in addition to physical improvement. Personally, after sitting most of the time for around 20 years, the first few months were quite challenging, however, with patience, persistence, and discipline I can proudly say I lost over 20 pounds and now I can kick over my head (◍•ᴗ•◍).

    The vibe and the support you get from the KMSY family are amazing, everyone is willing to help. Come and join us, looking forward to meeting you.

    Hello! My name is Kara Xiong and I am red/blackbelt.  I started in Tiny Tigers at the age of 5-½ years old and my passion for martial arts started growing each day.  I am passionate about Hapkido because it teaches me discipline and leadership skills.
