The arena director is the person in charge during the pow wow. Sometimes the arena director is referred to as the "whip man", sometimes the whip man is the arena director's assistant, and many pow wows don't have a whip man. The arena director makes sure dancers are dancing during the pow wow and that the drum groups know what type of song to sing. If there are contests the arena director is ultimately responsible for providing judges, though they often have another assistant who is the head judge. The arena director is also responsible for organizing any ceremonies that may be required during the pow wow, such as when an eagle feather is dropped, and others as required. One of the main duties of the arena director is to ensure that the dance arena is treated with the proper respect from visitors to the pow wow.
