Now you can choose to train with us on Zoom or in the Dojo!

Your safety is our #1 priority. So we have implemented thoughtful systems to give you the option to train in our beautiful dojo for your weekly semi-private lessons!

If you prefer to stay at home and train on Zoom, we are also offering semi-private and group classes throughout the week for you.


Current in-person safety measures:

-Everyone wears a mask and washes hands upon arrival

-Less than 10 people in the facility at any time (usually only 5-6)

-30 minutes of time between each in-person lesson allotted to clear the air

-Pads and equipment wiped down after each use

-Mats cleaned thoroughly daily

-Restrooms for emergencies only

-No direct contact


Is this really a good time to do Karate?

Here’s an email we received recently:

“Hey everyone at Boulder Karate, we just wanted to send a quick but heartfelt thank-you for being such a steadfast anchor for our kids throughout this pandemic. They’ve continued to be connected to their senseis (teachers) and to get regular, reliable activity in an otherwise disjointed and chaotic time.”

-Parents of two Boulder Karate kids

Upcoming events

Board & Brick Breaking Class

Sat Aug 15
Let's smash that COVID tension! Learn the nuances on board breaking with Master Randolph.



Martial Arts is fun and valuable for kids. We give them plenty of exercise and movement so they can let out that youthful energy in a positive way. They will also learn their self defense moves to advance to the next rank in a safe, encouraging environment.


Being a Teen is hard. So we love giving these young men and ladies plenty to take their mind off the stress of school and channel that into hitting the pads and training. The Teens class is welcoming and such a blast!


Our Adults program will get you in the best shape of your life, while giving you skills that could come in handy if you ever needed to protect yourself or a loved one. You’re gonna love it!
