With shorter days and caring staff, Ms. Abbott knows that the CVVA can help students stay organized and remain focused on graduating.

Outside of school you will find Ms. Abbott exploring the great outdoors with her son and Kilda, CVVA's resident Therapy Dog. Hiking, camping, and sporting events are always favorites, and Ms. Abbott loves travelling internationally over the long summer breaks.
