Nice hear your interest of Open Dialogue. I don't know how could I help you in your question, but I also feel that there has been lately growing interest about OD in Italy. I keep supervising regularly in Roma Frascati & Roma A Psychiatry and also planning to come to Trieste next year. In Modena I know many very talented dialogists and psychiatrist Fausto Mazzi knows more that.
If you are already a psychotherapist, you can always apply to Open Dialogue Trainers Training, which is held in Helsinki and next course starts 2018.
You can always ask me more about OD, and will help if I can.
Yours, Jorma Ahonen
