If you wish to attend in-person classes, please email us prior to your first class. 

In our practice, we look beyond our personal concerns to the safety of others and the well being of the communities of which we are a part. In addition, aikido training is unique in the amount and kinds of contact we have with each other. Our decisions for risk mitigation are made with both of these in mind. In this way, we continue to participate in the global effort to reduce transmission and mutation of the SARS‑CoV‑2 virus. The Delta variant in particular now disproportionately impacts many people here in Colorado, across the U.S, and around the world, especially those in unvaccinated populations.

Thank you for your patience and understanding as we add classes with the safety and health of our local and broader communities in mind.

Pre-registration is required for classes at the dojo.

Keiko classes require full COVID-19 vaccination and masks are required in the dojo.
