History
Our 2025 opening is spearheaded by the partnership of Hunter Jenkins, and John O’Brien. Hunter and John have trained together extensively, even cornering each other in numerous MMA bouts. Hunter and John were inspired to give back to the Kansas City and Blue Springs communities by instilling the values and skills gained through the sport. This has led them to establishing a Blue Springs martial arts academy – Crown City Athletics. The two are united in their vision to deliver premier professional training and a thriving community atmosphere. Our community is truly important to us. That inspired our name “Crown City”, derived from Kansas City’s nickname ‘Crown City’, symbolizing ambition, excellence, and leadership. As our martial arts academy grows, we will continue to strive to be the best spot for physical fitness training and martial arts classes.

What Sets Crown City Athletics Apart
At Crown City Athletics, we’ve built more than a martial arts academy. From expert coaching to cutting-edge recovery tools and a commitment to our local community, everything we offer is designed to help you thrive on and off the mat.
Starting with our name, we are entrenched in the Kansas City and Blue Springs martial arts community. We are not only building a premier training experience, but a culture that supports all skill levels, backgrounds, and personalities.
Our three head coaches are some of the most seasoned instructors around. With diverse backgrounds, including professional bouts, few can demonstrate the fundamentals quite like them.
One of our greatest benefits for our students is our anti-bullying strategies. We teach students the tools necessary to disavow bullying in their lives.
Not only do we provide Blue Springs martial arts classes, but we have physical /massage therapists renting out an office in our building or personal trainers for weightlifting, but not classes. We go beyond physical training, offering saunas, cold plunges, and massage therapists to help your body heal and thrive.
Our martial arts academy provides a state-of-the-art facility to train in. You can come in with top of the line equipment (sauna, cold plunges, massage therapists), expertise around every corner, and a welcoming and warm environment.
We understand that every athlete’s journey is different. That’s why our coaches take the time to personalize training to fit your goals — whether it’s competition, self-defense, fitness, or confidence. At Crown City Athletics, your success has a plan behind it.
