Welcome to the Mullen girls soccer page. The Mustangs annually compete with some of the best teams Colorado has to offer and usually advance to the postseason. A four-time in-state champion, the Mustangs have only allowed one goal in championship games. After nonleague, they will play matches in the Class 5A-based Centennial League during the regular season. Arapahoe remains the state’s all-time leader in championships won with nine. Cheyenne Mountain has six and Kent Denver five. Mullen is tied at four with Colorado Academy, Denver Christian, Heritage, Lewis-Palmer, Mountain Vista and Northglenn.
