Classes are structured and clear. The sensei's are great with kids of all ages as well as adults. Sensei Willy is committed to teaching his students the proper way to be prepared and not engage when not necessary.
They are awesome! 😁 For us being 1st time Karate parents we are very happy with how well they work with the kids. Very direct and clear on instructions for kids! After the first 3-4 days my kiddo caught on and loves it! They also give you a Good Habits form to help with behaviors at home and if you stick to it, it works AMAZING! ♥️ Thank you to the Sensei's!
Very experienced and professional, the dojo is very clean, the instructors do such a great job.
I highly recommend Colorado Karate Club. The Sensei are kind, fun, firm and humorous they are wonderful people who truly love what they do. I am extremely thankful for what they have done for my son. They want the best for their students and it goes beyond the dojo.
My grandson loves this place, they are great with the kids and its lots of fun watching them learn 😀 😊
I don't have any experience there but it sounds very good and I have 12 grandkids and I have four young adult women that I would like them to know defense classes I was abused when I was 12 years old and I feel that it would be really good for them to get the instruction and abilities to defend themselves
Beginner getting back into it after 40+ years with a minor disability. Felt very comfortable as an older adult and greatly appreciated the warm welcoming atmosphere. The sensei were patient and supportive, taking the time to demonstrate the moves, guiding me through them and giving me options when my disability prevented me from doing certain things. Even the kids were supportive and helpful, which shows the discipline and kindness they’re learning in the class as well.
Mis hijos disfrutan aprender karate lo recomiendo son excelentes senseis 👌🙏 mis hijos están aprendiendo responsabilidades en casa y comportamiento y sobretodo disciplina

ONE OF THE BEST DECISIONS WE MADE !!! Our daughter is about to be 5 and, she prefers karate class over ice cream 🤣😅. Her instructors are the ABSOLUTE BEST. it's a very positive environment.
Our daughter is 4 almost 5, putting her in Karate is one of the best decisions we ever made, her instructers are absolutely the GREATEST!!
Me encanta este club, a mi hija le encanta ir y convivir con sus maestros y compañeros, he notado más confianza y concentración en mi hija y sobretodo disciplina, 100% recomendado
Excelente
My son started a little over a month ago and he absolutely LOVES it. Everyone is so nice and welcoming. We will continue to come and cannot wait for his future accomplishments here at CKC.
Awesome place for students of all ages, and all skill levels! Senseis are patient, firm but fair, and truly care about their students!
We have really enjoyed our time here! It’s been about a year since we started in the pre karate classes and our son has excelled. Starting as a 4 year old boy had its challenges with focus but everyone is so supportive and kind. He’s learned so much and now confidently assists in leading warmups and is so proud of his hard work! Highly recommend ♥️
Great experience with my 4.5 year old. The instructors were very professional, smart, and helped my kid (and all kids in the class) focus and learn the basics. It’s a good experience for younger kids to learn discipline and listening skills. I’d recommend it for young ones to learn, have fun, wear out, and learn new skills.
This is a quality organization. Sensei Willy and staff are great with all levels. My son is thriving at this dojo.After many years at this dojo, we would absolutely recommend this organization. It's a great place for all ages, genders and body types to try karate. My son has learned the value of commitment and pride of success. He has also learned how to deal with loss with grace and character.
We love Colorado Karate Club - they have taught our 6 year old son so much more than just karate. They have taught him focus, patience, perseverance and team work, as well as how to compete, win or lose, with grace. They have provided him with opportunities to give back to his community as well as opportunities to just have fun with other members of the dojo. The senseis and senpais are so encouraging and fun, even while maintaining an expectation of discipline and focus. Seeing the pride on my son’s face each time he learns a new move, moves up in rank or gets to lead class warmups is the best. We’re very thankful for this program and all they do.
Karate and this dojo have made a lasting impact on my son. I truly appreciate the sensei's time, effort and discipline.He enjoyed and respected his time at the dojo.
always good
This is one of the best karate school my son has attended. He’s come along way in the last three years. He listens well at home and he listens very well at school one of their top students. Sensi Kyra is an amazing teacher, she always gives a motivation to keep it going and continue to do a great job no matter how many obstacles they might encounter. She develops a great relationship with the students and I appreciate her teaching ethic towards my child. I recommend this school 100%.
Great place of trust and good discipline for strengthening children's character.
It has been great to see the improvement that he has had in class and at home.
We have really enjoyed our experience at Colorado Karate Club. Our son started at 3 years old and has really shown a lot of improvements in listening, following instructions, and overall balance/agility. The Sensei and Senpai and very patient and take extra time to work with the younger students. Would really recommend this for physical and emotional growth of your child
Colorado Karate Club is great. My grandson loves going and learning new things. It has also helped at home a lot with discipline.
Great experience for kids my.son loves it
Estamos muy contentos de formar parte a lo largo de estos 3 años en Colorado Karate Club, la mejor escuela, mi hijo a mostrado excelentes resultados en su disciplina en casa, escuela y sus actividades extra curriculares gracias al personal del Dojo por ser parte del desarrollo de mi hijo.
Este año iniciamos nuevos retos con mi hijo más pequeño en la mejor escuela de Karate para trabajar y desarrollas disciplina, respeto, enfoque, concentración, atender instrucciones y muchas otras más, con apoyo del mejor equipo de Senseis, claro en Colorado Karate Club.
Estamos felices de formar parte de Colorado Karate Club, nuestro hijo ha avanzado no solamente en sus habilidades en el Karate, sino en su carácter, empatía, y responsabilidad. Es una excelente opción para los padres que desean ver cambios positivos en sus hijos.
Wonderful gym and community that has helped our 7 year old challenge himself mentally and physically.Thank you, Sensei Willy, Sensei Kyra, and Sensei Axel. Mateo looks up to you all and for good reason.I appreciate what you have done for us and the community as a whole.
Great for kids
Great family/locally owned business that focuses on character development while learning self defense skills.
My family and I have been with Colorado Karate Club for the last 3 years. There has been so much growth in the boys' coordination, character discipline, and even in their listening skills! I have loved it so much that I joined the boys' on the karate journey to a black belt! I love the body discipline this program gives me. Also, with the group working through various stances and moves to become smoother as a whole, and then to take that individually to better ones self. ♥️
My daughter loves going to class every week.
We love Colorado Karate Club. Great teachers/staff and they truly care about your children and their karate goals. Our son has been a member for over 3 years and his focus and determination have greatly improved.
We absolutely love Colorado Karate Club, their owner and all their instructors. They are very professional, fun and show a sincere interest in our son. We had tried other martial arts schools for our young son but Colorado Karate Club in Westminster has been the most personable with students and parents. They are invested in the betterment not just of Karate skills but in each students morals, life goals and focus on respectful actions in their personal lives. In the last year, our son has increased his grades, decreased his anger and become more responsible in all aspects of his life. I can absolutely attribute these in no small part, to this school and its lessons. Please consider bringing your kids or adults to this school and meet the staff and parents.
Wonderful staff teaching so much more than Karate! Grateful for the life skills and respect they teach. The staff genuinely cares about each student.
Una experiencia inolvidable para un niño sentirse seguro de si mismo.tener confianza y buena disciplina.. los maestros muy atentos..
We love bringing our little one to these classes, the sensei and the assistants are great, they pay attention to the details and teach them more than just physical, it’s also about discipline, leadership, kindness and team work. I truly recommend Colorado Karate Club, my kids is really happy and learning so much from each class.
My son has been going to Colorado karate club almost 1 year & we are so happy here. Seeing my child progress every month really shows how great this place is.
My son Jaxson has been With Colorado Karate club for almost 3 years now he’s doing awesome. His self-esteem is great. His confidence is built. Do a very awesome job. I couldn’t be more pleased thank you to the staff the sensei they’ve all spent time with my son at both dojo‘s.

Gracias colorado karate !! Es lo más fantástico k e encontrado para mi hija!!’ Se le a enseñado disciplina ,,, empeño ,,,y esas ganas inmensas de superación cada día !! Padres es la mejor oportunidad y opción para sus hijos también !!! 100% recomendado …..
I am a former student of Sensei Willy. My name is Chaplain Candidate 1LT Dane Barnes, and I currently serve in the United States Army Chaplain Corps. Recently, I graduated from our Chaplain School (CHBOLC) after three years of service in the Army Reserves. Being in such an austere environment, there were a lot of times that I thought back to how my formative youth at Colorado Karate Club prepared me for military discipline.In the Army, there's a lot of Doctrine and regulation....but the actual yearning to do good and be upright starts within. During one of our courses on the Army Ethic, I couldn't help but think of the Dojo-Kun; Particularly the element of: "seek perfection of character." Army Chaplains have to possess the mental and moral fortitude to accompany soldiers into the most dire situations, at their own behest. That requires a tremendous amount of willpower and self-discipline consistent with moral development. I know that the Dojo provided me with an ethical, mental, and spiritual framework that has helped me to meet those requirements.I absolutely commend Sensei Willy Stromeier for his dedicated instruction at Colorado Karate Club, not just in educating others in self-defense, but for the critical aspects of discipline and moral integrity which his Dojo embodies.
They all do a great job teaching! My daughter loves being part of a great karate team!
We are so happy with Sensei Willy. My daughter loves her Karate class. The class has helped her gain more confidence. He is encouraging, and great with the kids.
Es maravilloso seguir mirando los progresos mí hija se los recomendó !!!
Highly Recommend!My 3-year-old daughter has been attending this karate dojo in Brighton, and we couldn’t be happier with the experience! The instructors are amazing, patient, and truly know how to engage young children. They create a fun and encouraging environment that makes learning both enjoyable and rewarding. My daughter has gained confidence, discipline, and new skills in just a few short months. We love being a part of this supportive community and highly recommend this dojo to other families!
This dojo is respectful, kind, very nice and patient with the children and they do an outstanding job meeting every students needs.
What a way to build confidence.We have been coming for 5+ years. So much personal growth it is not just physical but mentally. Learning to be self-confident, self-aware, understanding, listening, teamwork, self reflection, and so much more. What an amazing group of people bringing the best out of each student.
Es una escuela muy completa, mi hija tiene ya más de 2 años platicando ahí. Estamos muy felices.
Quiero recomendar ampliamente, Colorado Karate Club!Mi hijo tiene mucha disciplina, los Sensei son muy buenos consejeros y tienen mucha experiencia en lo que les muestran a sus alumnos! En días pasados mi hijo cumplió años y recibió un bonito detalle por parte de ellos, muchas gracias por todo!
Excelentes maestros son respetuosos amables y pacientes con los niños mi hijo siempre está feliz de ir a su clase y al final de su clase sale muy motivado para regresar .
This place is the best. My daughter has gotten more disciplined and gets unusually excited to get so physical. I love how they focus on character building, discipline and working with others, as well as a lot of Japanese traditions. 10/10 can’t wait to see how my daughter continues to grow and learn.
Our kids have been in the programs here for over two years and we could not be happier with the experience we have had. The discipline they have gained shows at home and school. The physical fitness they have is amazing. And the skills they have learned will last them a lifetime. We highly recommend CKC and Senseis Kyra and Willy if you are looking to get your kids or yourself into martial arts.
EL MEJOR DOYO DE COLORADO. SE PRACTICA EL ARTE MARCIAL CON EXCELENCIA , EL AMBIENTE ES EL MEJOR. APESAR QUE SE SIGUEN LAS NORMAS AL PIE DE LA LETRA. UNO DISFRUTA LAS CLASES AL MAXIMO .TAL VEZ MUCHOS DIRAN QUE EL ARTE MARCIAL ES ESTRICTO PERO DE LA FORMA Y LA CARISMA CON QUE TODOS LOS SENSES LLEVAN A CABO LAS ENSENÑANSAS HACE LA DIFERENCIA. COLORADO KARATE CLUB NO ES SIMPLE MENTRE UN DOYO O UN NEGOCIO ES MAS QUE ESO.ES UNA GRAN FAMILIA QUE CON ORGULLO PUEDO DECIR QUE HOY SOY PARTE DE ELLA Y ME SIENTO PRIVILEGIADO POR SER PARTE DE ELLA . A TODOS LOS SENSE SIGAN ADELANTE CON ESTE GRAN TRABAJO Y ESFUERZO PORQUE ESTAN DEJANDO HUELLAS NO SOLO EN LA ENSEÑANZA SI NO EN CIENTOS DE VIDAS INSTRULLENDONOS VALORES, RESPETO, CONFIANZA , motivacion no solo en aprender la defensa personal si no que en muchos aspectos de la vidaatt. Felix W. Rivera
Great for kids and adults of all ages. My son started here at age 3 and is 5 now still loving it. He’s learning discipline as well as gaining coordination and strength.
Love this dojo!! Great environment and the kids have a great time while learning karate!!
My son has been going to colorado karate club for going on 3 years. He has came a long way. An they take time with the students to get better in karate and at home and school.
Amazing we love being part of Colorado Karate club❤️Este lugar es genial a mi hijo le encanta esta escuela de karate 🥋 ❤️
We have nothing but wonderful things to say about Colorado Karate Club. Our three year old looks forward to visiting each and every time. Willy Sensei and all of the Senpai that work with the younger class are genuine, enthusiastic, and professional. It is amazing to see the determination and enthusiasm of a preschooler when they are being guided with so much care. We highly recommend CKC to anyone who is wishing to go the extra mile for themselves or their child.
We have been a part of this amazing karate club for over two years and couldn’t be happier with the experience! The Senseis and Senpais are not only highly skilled but also incredibly patient and encouraging. They foster a positive, disciplined environment where students of all ages and levels feel welcome and supported. Our son has grown in confidence, focus, and strength, both physically and mentally, thanks to their teaching. If you're looking for a karate school that offers exceptional instruction and a great sense of community, we highly recommend this club!"
Its been a great experience here! I admire the instructors they are so great with the little ones in Pre Karate. Highly recommend!!
All of the instructors are good. Everyone works hard.
I HIGHLY recommend Colorado Karate Club. My son has been with them for over 5 years and it has been an incredible experience. Sensei Willy is awesome with kids, he is so positive and encouraging. Overall an amazing program! My son LOVES it!
Excellent teaching staff and programs. My whole family enjoys the club! I would highly recommend this dojo for anyone or any family wanting to learn self defense and improve physical well being!
Class tonight was so fun as always!
We love this place! My family of four has been coming here for a year now and the staff are why we keep coming back! They are all wonderful and keep the kiddos engaged. This is great for families!
There are very kind teachers and they work you to there limits if you need a break just tell them and they will exit you to where you sit
Colorado Karate Club has been a great place for my energetic son to learn focus, discipline, confidence, and enjoy learning about karate principles. I highly recommend the classes here.
Es lo mejor para que los niños agarren un muy buen entrenador y disciplina
I can’t say enough good things about this studio! We attended classes as a family of three generations for over a year. It was very fun and motivating to take classes together! I lost 50 pounds and was inspired to make positive changes in my life.
We love Colorado Karate club!This is a place where children and adults grow in their strengths. I can clearly see that my daughter became more confident and much stronger. She’s been learning to accept mistakes and deal with frustration. She’s been developing stronger emotional regulation skills.Sensei Kyra is a great role model for children and managed to build feelings of trust, safety and well-being. She definitely understands different kinds of children’s personalities, cares very deeply about their progress and helps every child to reach their fullest potential. She is always calm but firm when it comes to discipline. She has a good sense of humor and children love that.I am impressed how kind all participants are and they do their best to help each others.I would like to admit that the every member of the team deserves kind words and each of them contributes to children’s success. They all show respect and and love to every person in class.
This place is so much more than a karate center, it truly is a community where family members learn the art of karate together, friends teach each other, everyone cheers for the growth of individuals, and kindness and discipline is instilled in everyone as they enter the doors. Our son has been going there for 8ish months and he is growing so much - learning karate but also focus and leadership. I couldn't recommend place more!!!
We have been coming here for about 5 months now and my son absolutely LOVES it! The team is wonderful and although my 4 year old cant sit still for a second, they are very patient with him and teaching him so much! Sensei Kyra goes above and beyond to make sure he Continues to grow and do what he loves. we 100% recommend Colorado Karate club
As a martial arts gym owner myself, I can honestly say Colorado Karate Club is the most professional and clean academy I have ever seen.What a great place run by a great instructor!
Sensi Willie is so wonderful with the Pre-Karate class! He is so kind and patient but also teaches the kids discipline. It's such a great experience
Our kids have learned so much since starting Karate. Their excitement to progress and achievements as a Parent is the best feeling ever. We love the community there and Sensei Willy has made a big positive difference in our boys life. He Keeps them on their toes and talks to them personally about being better. Every kid should have a Role model besides their parents.
Our family has been enrolled at the Westminster dojo for a few months now and we love it - my grandkids under 10, their mom in her mid 20s, and my wife and I around 50.Senseis Willy & Kyra and their assistants teach traditional Shotokan karate with a good mix of discipline and fun. There's zero mention of professional fighting or MMA ... just technique, achievement, and mutual respect for each other and the dojo.They have pre-k for kindergartners, plus beginner, intermediate and advanced levels for all other ages and experience.The instructors are very accommodating to our aging knees and my weight and back injury. For example, I can't do sparring, falls or takedowns, or lay on my back for some parts of the warm-up. And when I've reached my limit, I can slow down or take a break. And that's fine, but everything I can do, they encourage me to push to my safe limits.So for me it's been a great way to stretch, exercise and revisit techniques I knew when I was much younger. I've even lost a little weight since I started.I can't recommend them enough.
Before moving to Northern Colorado, I had the pleasure of attending Colorado Karate Club with my two kids, ages 10 & 7. The folks at CKC not only do a fantastic job of teaching karate, but they've also created a wonderful community.I loved observing how the program challenged my children. Throughout their experiences, they learned discipline as well as seeing first-hand what they could achieve both physically and mentally; things they didn't think they could achieve prior to challenging themselves.For myself, it was a fantastic journey to take with my children. I highly recommend being an adult participant! I also learned what I was capable of achieving, while also obtaining priceless shared experiences/ memories with my kids. Thanks for everything you did for the Haller family, CKC. We very much appreciate it!
My son loves the classes. His attitude has improved greatly. Thank you!
We love this karate place. Sensi is very kind and genuinely cares about this students.
It is new to this location but not far from us and my daughter enjoys it
this is a great place for children and adults highly recommend

CKC is a great place for kids and adults to be learn the skills and discipline in Shotaken Karate in a safe environment. This is a family owned and oriented business. From Grandmother, Father, mother, children and grandchildren to all students who actively teach and learn.

My son has been going here for about 6 months and really enjoys it. The staff does an excellent job working with and teaching the kids. Excellent place!
100% best place to learn shotokan karate In the world period.
Sensei Willy was outstanding at our introductory appointment. He was engaged encouraging and passionate.
Seriously the BEST decision we could have made! Both of my kiddos joined at 3 yrs old. We are proud to say that we are still members 4 years later! The amount of growth, strength, confidence, character, discipline, and leadership my kids have thanks to CKC is amazing. We have found so much more than karate class here. We found a community. A family.THANK YOU CKC! We are blessed to know and train with you all ❤
