Alena Mess initially worked primarily with offenders. She worked (including as head of department) in the prison system, in social therapy and in preventive detention. Today, she advises schools, police authorities, children and families on the prevention of sexualised violence and cybergrooming and works as a couples and sex therapist (www.am-paartherapie-hamburg.de; www.am-praevention-sexualisiertergewalt.de) . She disagrees with the often-held view that you can either work with perpetrators or with victims and is convinced, on the contrary, that the best way to prevent crime is to know both sides.
