This article suggests that psychoanalysis can take place both in the private office and out of the office in community-based settings. It provides historical background about the way in which psychoanalysis came to be thought of largely as an office-based practice for an affluent, culturally specific clientele. The article describes efforts at training candidates and students in the use of spontaneously occurring interactions in community-based settings in a range of cultural and socio-economic contexts, in order to illuminate unconscious interpersonal and intra-psychic dynamics. It suggests that the mentalization fostered by psychoanalytic processing of these interactions can provide an important protective element to an expanded range of people against the inter-generational transmission of trauma.
