Calasanzs dynamic system of self-defense known as Street Survival applies martial art techniques for use in the streets. The student gains skill and develops endurance as he progresses through the various defensive methods. Street Survival orients the student to practical responses to self-defense situations where a traditional or classical martial arts response would be impractical.
Calasanz has also developed Self Defense for Law Enforcement, which is specifically designed with the needs of law enforcement professionals in mind. In a non-competitive environment, Calasanz guides officers through a series of controlled techniques designed to develop, sharpen and maintain defensive skills. Law enforcement professionals are taught the essential tools unique to The Calasanz System, that can be instinctively activated when confronted with a threatening situation. Control by oral means is enhanced in a combination of multiple scenarios. Handcuffing techniques are also practiced.
