Announcement as of 6/23/2020

Dear RCMA Students and Parents,

You've probably heard the news that San Mateo County businesses like ours are being allowed to reopen..that includes RCMA. 

We couldn't be more thrilled to finally get to see you again; however, the process of reopening and supporting local businesses is very confusing for everyone. We are trying to navigate all the regulations and develop guidelines in order to reopen and still be able to teach our students effectively.


We understand that many of you may not be ready to return to the dojo yet. Please know that we honor where ever you are on this and that everyone has varying opinions and comfort levels. If you decide to return to the dojo at this time, please be patient with us as we will be doing our best to be in compliance and keep the integrity of our mission. The decision to reopen RCMA will come with some new guidelines and regulations to keep everyone safe. It has always been a priority for us to provide a safe, clean and positive learning environment for our students and now so more than ever. 


Listed below are the guidelines and regulations we will be implementing (these guidelines may be temporary and can change at any time):

  • Please do not enter the dojo if you are or have been sick-you must wait 14 days before returning

  • Practice social distancing upon entering/exiting, checking in and observing

  • After checking in, parents of age appropriate children are encouraged to wait outside and return when class is over (we will have a small waiting area)

  • Hands and Feet must be sanitized before entering training areas or wear clean grip socks or clean wrestling or karate shoes only for the mats (Hand washing station or bathroom for hands; bring own wipes for your feet) *see below

  • Temperature checks by staff members before entering the facility

  • Come dressed and prepared for class in clean uniform or training apparel 

  • Optional designated training partners

  • Bring water in a reusable bottle (we encourage you to not bring single use bottles, please)

  • No personal items or gear to be stored at the dojo

  • Restrooms will be limited to one person at a time

  • No hanging out after training sessions

  • Children 12 years and under are never required to wear a mask- see Who Is Exempt? at

  • Masks are not required while training but may be worn or carried when not training

  • Do not share equipment

  • The ‘Little Room’ is no longer available at this time for kids to hang out

  • Our roll up doors will be open during classes to allow maximum fresh air circulation (weather permitting)

*We will have a hand washing station outside our entrance in addition to the bathroom and hall sink and touch less hand sanitizer available. In addition, we ask that everyone bring their Own Sanitizing Kit including hand sanitizer and wipes... for feet and personal equipment). We will be wiping down surfaces in between classes. 

We will continue to do some ZOOM classes; however, the time and days will be changing as we will be doing them simultaneously with the modified class schedule-see schedule below. This schedule will be temporary as we assess flow, attendances, teacher availability and time to clean and check in students in between classes.
