Message from the Orange Belts

For our Ee-Dan/ Dan Candidates

Cornerstone is set to reopen Monday June 22nd

Because of Covid-19 our Schedule has Changed for the latest dates check out the Calendar

We hope this finds you and your family in good health and spirits.  We are writing today to discuss Cornerstone's plan to reopen on June 22, 2020.  States around the country have been reopening their businesses with a 3-phase plan provided by the Federal government, based on recommendations from the CDC.

We will be instituting a number of requirements for students and their families who will attend classes at Cornerstone.  These changes will be temporary as we deal with the retreat of this virus and restrictions will be modified based on recommendations from our state's reopening committee.


Here are some of the procedures that will be implemented upon our reopening and your return to your school:


1.  Students should wear a mask to and from the school.  Masks will not be required during training.  For the time being, all students should come to class already dressed in their uniforms.  The changing booths are closed.


2.  Parents will not be allowed to spectate during class times.  They may either wait in their car or drop off students as long as they return on time at the end of class to pick up students.  We will not/cannot permit students lingering around the school between classes.  If you need to speak with an instructor, you will be required to wear a mask and maintain 6 feet social distancing during your conversation.


3.  All students upon entering the school will be required to have the bottom of their shoes sprayed and then placed on the benches.  They will then be required to clean their hands.  They will then be directed to the appropriate spot on the dojang floor where they will be expected to remain throughout the class.  There will be no contact between students, therefore all sparring and partner self-defense practice will be temporarily suspended.


4.  Instructors will maintain the required 6 feet of distance from students at all times.  Instructors will verbally and visually direct students.  Until further notice, there will be no personal contact between students and instructors.


5.  Bathroom use will be limited.


6.  At the conclusion of class, students will be required to wash their hands, put on their shoes, put on their masks, and leave the school.  The dojang floor will then be sanitized.  The next class will be allowed in and they will follow all the rules of #3 above.  This procedure will be followed with every change of class.


7.  All 6-month membership agreements will be cancelled and restarted as of June 22, 2020.  Those with annual agreements will be extended 3 months.


8.  For those who were ready to test or coming up for testing, we will be evaluating each student's capabilities and will be available for extra assistance if necessary to get each student up to speed again.


It is time to get Connecticut and Cornerstone School of Karate up and running again.  We will do safely and in accordance with CDC recommendations.  If you have any questions, please contact us at

We will remain in contact with you by e-mail to keep you updated with the status of the school. You may also check our facebook page: Cornerstone School of Karate  or our website:

Cornerstone School of Karate

Thank you for your interest in Cornerstone School of Karate and Tang Soo Do Mi Guk Kwan, Association, Inc. 

The martial art known as Tang Soo Do is relatively modern. However, its basis, the Korean disciplines of Soo Bahk, and Tae Kyun, dates back many centuries.Tang Soo Do is a composite style influenced by Northern Chinese arts, Southern Chinese arts, and the Okinawan discipline of Karate. Tang Soo Do is considered to be a classical martial art. As an art form, it is primarily concerned with scientific and martial theory, form and aesthetics. Because of it’s martial emphasis, the Mi Guk Kwan is concerned with the natural evolvement of practical and effective self-defense techniques. Tang Soo Do Mi Guk Kwan practitioners care about each other as “family”. As part of the Mi Guk Kwan family, you will experience tremendous growth in knowledge and strength. Your growth will be a direct result of your efforts and the efforts of your certified studio instructors. Your Tang Soo Do Mi Guk Kwan Association has a responsibility to provide you with a clean and safe training area, the highest quality instruction and intra-association communication. Your membership card will be accepted at all Tang Soo Do Mi Guk Kwan Association Studios in the United States and affiliated studios in foreign countries.
