The Directors of Lab Rats are the elected officers.  They each take care of a different department in the group, although the three performance coaches, who cook up the fine cuisine you see on the stage, have to work a little more closely with each other than they do with the others.  The technical director is the man who adds those stellar light and sound effects to every Lab Rats show.  Finally, the managing director, the only member of the troupe who cannot perform on a regular basis, is responsible for all the management issues behind the scenes.
