Have been running my own consulting and seminar business within the field security and safety for over 20 years. My main field of focus is to teach employee, coordinators and management how to prevent, predict and deal with negative behaviour, threats and physical violence from potentially aggressive guests, clients, patients, inmates, residents and so forth. I have trained and taught martial arts for 30 years, specialising in the field of self-defense. Graded 6. dan in ju jitsu with the title of shihan. Main hobbies include music (playing guitar), writing, blogging and web-site building.
