HELP! I'M STUCK IN TRAFFIC! Remember the importance of carrying your schedule and the phone numbers of your fellow officials. Call or text ahead if you know you are going to be delayed. In addition, if you are the one that's already at a match, leave your phone out until your crew has arrived. They may be trying to call you! Once the whole crew has arrived, turn it off and put it away.

We are looking for officials to join our team! Michigan has a lot of volleyball and is always looking for people to officiate this amazing sport.
