This article reports on possibilities and challenges in the implementation of the Family Health Strategy in a municipality in Southern Brazil, based on the experience of a female undergraduate medical student at the Chapecó Community University (Unochapecó). The experience occurred in the context of one of the projects approved by the Educational Program for Health Work (Pró-Saúde), entitled Interdisciplinary and Multi-professional Experiences, which includes tutorships and observation activities in primary care in the municipality, involving students and faculty from ten undergraduate courses and staff from the Chapecó municipal health services. This observation detected the following difficulties: a limited health team in terms of the diversity of professionals, which is necessary for the health promotion activities in the community; low commitment on the part of users; flaws in the physician-patient relationship; and low level of work satisfaction among some of the health professionals. Improvements included greater staff commitment and closer collaboration between the health unit and the social assistance department in favor of inter-sector work.
