A shoulder problem forced Castellano to withdraw from The Donnas' tour following a show on December 27, 2008 at the House Of Blues in Anaheim, California. Amy Cesari of the band The Demonics filled in on future tour dates. On July 9, 2010, Castellano announced on the band's website that due to her shoulder she would have to retire from drumming and performing with The Donnas. Castellano still attended events the band was involved with as well as promoted the last album she recorded with the band, Greatest Hits Vol. 16.
