The Diamond Dolls Twirling Team, based in Derry, is in their 18th year, established in 1999. The team is open to girls, ages 4-17 years old, from any school district, with or without baton twirling experience. Parade/Performance teams only, as well as Competitive teams, and private lessons are offered. Classes are assigned based on age and skill level, including Beginner through Competitive.

They are a familiar site at the Derry Memorial Day and Railroad Days, Blairsville Knotweed, and Latrobe Fourth of July & Christmas parades.
