This research had as main objective to open possibilities of an ethical and political meaning for the territorial action in health as an intervention in public health, through the Family´s Health Program, based on the experience of professionals who perform it. The scenery of the study is the public policies field concerning health care. Such investiment was due to rare systematic studies on the theme, in order to deepen some reflection on the professional formation for this kind of intervention. Yet, it showed a possibility to point reflections on the evaluation of the Family´s Health Program. The research is based on the existential phenomenological approach and on the oral narratives methodology. The colaborators were nine public health professionals from Cabo de Santo Agostinho-PE, engaged in the strategy of the territorial action in health through the Family´s Health Program. In order to collect the narratives, two moments were designed: a group discussion and an individual interview, some time after the group. Both procedures provided a situation for the professionals to talk about their practical experience in such a kind of action. The methodology was appropriated to promote experience, making it possible to think out a way of caring in order to produce meaning for their work. In this sense, the procedure presented itself as a way of taking care of who takes care, highlighting a comprehension of research as an intervention act, as pointed by the Clinical Social Psychology referential. The narratives interpretation indicated various aspects about the theme, such as: discrepancy between the objetives of the program and the real/possible action, importance of thinking over the context for professional formation, need to reflect on the acting and difficulties to construct an effective collective job, as required by this kind of territorial action in health.
