This single case study aims to reflect on group work in diabetes mellitus, carried out by a multiprofessional team in the education program implemented by a Preventive Medicine Service - SEMPRE. Data were collected from SEMPRE's internal documentation and through direct and participant observation by the researcher during the activities were adults and children with diabetes. These reflections occur in line with the initial formation of a group,: referral, selection and grouping. This way of working allowed for greater efficiency and lower cost-effectiveness in the education programs, requiring investments in continuous education for the multiprofessional team. Thus, there is a need to unchain a process of internal cooperation. Moreover, each health team member's knowledge needs to be made available.
