Who We Are
Culture of Safety is a Chicago-based (Rogers Park, to be exact) small business. We are women and queer-owned, and were founded in May 2019 to offer empowerment-based violence prevention trainings. Examples of the trainings we offer for adults are empowerment self-defense, bystander intervention, and workplace safety. We also offer classes for young people, such as self-defense & bullying prevention for kids, youth, and teens in Chicago and surrounding suburbs.
In June of 2020, during a global pandemic, we created Jin Sei Ryu Chicago to offer karate training, offering classes first online and then outdoors in nearby Warren Park.
In August of 2022, we opened our storefront at 6961 N. Clark, between Morse and Lunt Avenues.
We serve individuals in public classes in the Rogers Park neighborhood of Chicago. We also work with organizations such as small businesses, large corporations, schools and educational facilities (K – 12 and higher education), nonprofit organizations, and private groups. Culture of Safety strives to live up to its name and help our clients create a culture of safety and mutual respect in their environments, and to help people know that they are strong and capable of keeping themselves safe in whatever environment they find themselves in.
