Full class schedule

This includes classes for all ages/stages as well as options for  intermediate and senor youth, teens, and adults. There is also a Google calendar for classes you can subscribe to, which includes all cancellations.

Simple Text notifications

We use the SimpleTexting platform to communicate with students via text and for last-minute announcements and notifications (such as closures). If you consented on your Participant Information form, we will add you to the platform. You will receive a text when we do so. To add additional numbers, text @coskarate to 847-500-0049. This is also the number from which you will receive automated texts from us. In addition to informational texts, we send reminders we think will be of interest to you, such as special workshops.

Our Jin Sei Ryu Chicago Policies and Codes of Conduct

At Culture of Safety Dojo and Wellness Center, we take the safety and dignity of our students and participants seriously. Our karate program is our most significant ongoing program, and as such it is important to us (and to Jin Sei Ryu Karate-Do International) that we have robust student protection mechanisms, including Codes of Conduct and well-articulated Complaints Procedures.
