A new prospective of treatment in Mental Health Center: theorical reflections - The present work is a result of a reflection on the impact that the Multi Family Groups experience had on the workers on educational and professional levels, as well as on working level. It shows how it is possible to share such experience despite the differences in the professional formation of the workers and how close the theory behind the psychotherapeutically work of the MFG is to the practical work. With the emotional state called surprise (the leitmotiv of this work) comes a synthesis of important emotional moments that have been present in all the meetings and that provoked in the workers a copernian revolution of attitudes and perspectives. It brought us to focus on some crucial points that changed our habitual ways of thinking and working: 1. the educational experience: you can actually start from the practice and consequently get close to the theory; 2. the therapeutic experience: you can get into touch with yourself only after getting into touch with others; 3. the working experience: you can make a diagnosis starting from the evaluation of the sane parts; 4. the professional experience: you can place less emphasis on the therapy techniques and therefore use the therapists personality as the main or fundamental therapeutic instrument. To conclude, we can say that this experience solved some of the doubts and at the same time, offered others followed by mind opening and by a certain relief that brought the possibility of using also our subjectivity in a course of therapy.
