    I am so excited to start the 2019-2020 school year with your child. I would like to start off by telling you a little bit about myself.

    My name is Jill Kostich. This is my 24th year in the Kyrene School district.  I taught 17 years at Kyrene de los Niños and this will be my seventh year at Estrella. I am so excited for this opportunity to teach your child and I look forward to a fantastic school year!

    On a personal note, I  have two daughters named Isabel and Alexandra. Isabel is 22 and a student at ASU.   Alexandra is 16 and is a juniour  at Desert Vista.   I have an organge  cat named Arie, a tabby cat named Toni, and an energetic rescue dog named Oscar.  When I’m not working my passions are watching football,  running, working out, reading, and drinking coffee!!

    We are going to have an amazing school year!!
