MZ Congressi

PCO (Professional Congress Organizer) founded in 1987 directly by the President, Mauro Zaniboni and managed by a board of three Directors: Mauro Zaniboni, Monica Sellari and Stefano Montalbetti.

MZ Congressi is the oldest division of the MZ group, with Headquarters in Milan. A thirty one years’ experience, gained in the medical-scientific sector, especially in the Laboratory Medicine field, combined with quality and versatility are our main characteristics.

MZ Congressi is a company controlled by MZ International Group srl, which is the holding of three more active companies:

  • MZ Incentive srl: in the world of incentive and conventions
  • MZ Associations srl: all services for non-profit medical & scientific Associations
  • Venezia Congressi srl: conventions and events in Venice and all the Region of Veneto.

MZ CONGRESSI is proud to be a partner of the important project FOOD FOR GOOD, a project created and found by Federcongressi & Eventi in cooperation with Banco Alimentare ed Equoevento for the recycling of the excess food from the catering of events and congresses. Thanks to this important work, we managed to recover 67.831 meals       and 4.669 kg of bread and fruit destined for charitable institutions. In 2016 MZ Congressi gained the Prize as the Best Italian Company, among the Partners of Federcongressi & Eventi, to have recovered excellently the excess food during our events of 2016.
