Ample space is given to the account of social design and the intercultural and interdisciplinary breath that led the operators and services involved to initially address the migration issue and its critical issues in terms of isolation, risk of stigmatization, discomfort and marginality through a complex and integrative observation.) We focus on outlining how the care of a group of women united by crossing a central phase of the physiological life cycle, has made it possible to create a place with preventive values at various levels and the co-construction of group experiences, which navigate differences, reveal similarities and create hybridization. Space is also given to the social changes that the group has undergone, to the role played by the pandemic and to the new developments in being, to the considerations of the writers regarding the professional and social enrichment that the experience has given.
