June 7th 2021

Ikeda sensei is now holding a second weekly class in the dojo on Mondays at 7:00pm for those who have completed a COVID-19 vaccine schedule. If you wish to attend, email us or contact Ikeda sensei directly prior to registration. In keeping with current guidance from Boulder County Public Health (BCPH), we have increased the size limit, to 23. Note that weekly pre-registration through Zen Planner is also required for this class. Please do not simply show up or register through Zen Planner without getting in contact first.

On May 16th, Boulder County entered Level Clear. Boulder County Public Health (BCPH) and the State of Colorado have both modified requirements and recommendations since the 16th and we're sorting these out now. Until we do, indoor classes other than Monday and Thursday remain limited to 12, with masks for non-vaccinated people and pre-registration through Zen Planner also required.


Thank you for your patience and understanding as we build our schedule with the safety and health of our community foremost in mind.

Pre-registration is required for classes at the dojo.
