Shoshana Simones

“I am currently the part-time Community Engagement Manager for Mission of Mercy, a nonprofit that provides free primary healthcare to the uninsured across the Valley. Prior to MOM, I spent six years with Make-A-Wish Arizona as a Wish Manager, where I planned over 500 wishes for children with critical illnesses.

From 2010-2011 I served on the AVACA Board while working as the volunteer coordinator at Free Arts for Abused Children of Arizona. I was the PR Chair and even designed the “puzzle piece” AVACA logo! I gave our logo a refresh in 2022, as well.

I also run a small marketing firm where I create content and manage email marketing and social media for a variety of businesses.

I have two daughters, a son, and a giant Labradoodle named Booker. I love sushi, art, and sports!”
