Delaney Greaves
Colorguard Instructor


Delaney Greaves spent all of her high school career at Cajon High School spinning in the colorguard. She marched three Fall seasons with one show taken all the way to State Championships, and four winterguard seasons with 2 bronze medals, in the Gold Star Regiment.

Her high school colorguard experience was followed by a season overseas in Paris, France with the RCC Marching All Stars Honor Band. There, the band marched down Champs-Elysees on New Years morning of 2016, being the first marching unit to do so since World War II.

Delaney hopes to take these experiences and knowledge of the sport and hand it down to the next generation of guardies in this season’s Gold Star Regiment!
