The purpose of the article is to present the activities of Youth Prevention Leaders. The research shown in the article presents activities carried out by youth leaders and also their biographical and personality conditions. The research included 20 prevention leaders who act as part of universal prophylaxis in one of the Upper Silesian cities. A focus interview was applied with the leaders, analysis of the documents and an open interview with the program's supervisor. I show in the article the biographical and personality conditions of the leaders, the reasons for engaging in this activity and features and competences. I also discuss a their benefits, difficulties, successes and needs. In effect of the conducted research I selected three types of leaders: an activist, a conscious motivator and a goal driven individual getting out of the shadow. The analysis shows that the effects of activities carried out in schools in which youth leaders are present, are definitely better than in schools where they do not work.
