The Executive Staff
The IMUNA Conferences are a series of MUN conferences organised by students of the Murmellius Gymnasium for students around the globe. Because of this, the IMUNA Conferences are not only fantastic conferences, they are a learning experience for all involved as well. The Executive Staff is responsible for the day-to-day running of the conference. They all have extensive Model United Nations experience and possess excellent organising skills.
