Kids martial arts classes focus on character development, physical fitness, and self-confidence, and teen martial arts classes offer individualized instruction and support for students of all abilities. The program also includes mental conditioning and awareness training such as the OODA loop and threat response, personal protection classes with less-lethal options, and a job placement pipeline that combines BSIS certification with career guidance.
The organization states that it provides top martial arts, firearms, first aid, and security protection training in Oakley and describes its approach as real-world readiness.

Parent and participant feedback includes comments that instructors are described as great, personable, professional, friendly, and flexible, and that staff treat everyone with respect. One testimonial notes that the academy has provided instruction to multiple generations in the same family, and another mentions enrolling a child after an incident at school and then enrolling additional family members. A participant reports a positive experience in a CPR class and describes the instructor as helpful and responsive to questions.
