    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 Kuk Sool for over 26 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 2016, Master My obtained her Fifth Degree blackbelt.

    Aside from her instructing and training at KSMY Martial Arts, Master My is also a blue belt practitioner at Yemaso Brazilian Jiu Jitsu. My Gwan Jang Nim also loves to dance salsa at Yemaya Salsa Dance Company.  My Gwan Jang Nim is a mother, wife, and an avid dog lover.

    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 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.

    Elizabeth Kim

    Hi! My name is Elizabeth Kim, but you can just call me Elly.  I have attended martial arts for a eight years.  I have learned many things at our dojang.  I’m glad that I am a part of the KSMY team and don’t know what I would do if I wasn’t.  I have met many great people here and we are all very good friends.

    I attended KSMY for self defense, but realized it’s also a nice place to go if you want to relieve stress.  The people are really kind, so it’s nice to have others always supporting your passion.

    KSMY Martial Arts is a great place to learn respect, self discipline, and perseverance.  I am still a continuing students but have improved since I first step foot into this dojang.  I currently assist in the Tiny Tigers, Junior beginner classes, and help lead the Youth & Adults classes. I hope to meet you soon!

    Derrick Rogers

    Hello!  My name is Derrick Rogers. I have prior experience in Judo and Hanmudo. I began my journey in Kuk Sool when I moved to Sacramento and was looking to get back into martial arts after many years of inactivity. I have been training at KSMY for about 3 years, receiving my brown belt in the process.

    Under Master My’s instruction, I have regained my passion for martial arts. I have become more confident as a person and I have notice 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!

    Mary Ramos

    Hello everyone! My name is Mary Ramos and I currenlty assist the Tiny Tigers and Juniors classes.

    Martial arts teaches me to respect myself and others, be willing to learn, and keep an open mind.  I train Kuk Sool to broaden my perspective on martial arts as well as to help other students reach their goals.  My favorite part of Kuk Sool is the wide range of techniques that can be applied.  With time and practice, executing these techniques become second nature to the martial artist so they do not have to think twice on how to defend against an attack.  Learning martial arts requires that one practice with patience and perseverance while maintaining a humble state of mind.  The comprehensive curriculum taught at KSMY reminds me that there is a lot to learn about martial arts and the way to progress is to practice.

    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 Kuk Sool.

    I look forward to one day becoming a Black Belt under Ma’am My’s instruction.

    I have learned so much from not only My Gwan Jang Nim but also from Sir Cameron, Sir Caleb, Sir Glynn, Sir Shayn, and Ma’am Elly.

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