KidzMash Committee

It takes an amazing amount of work to plan and execute our family track. In 2014 we had over 250 kids in our program. That is more than all of the attendees and speakers of the first CodeMash. We expect over 650 kids this year. The program has a mix of fun family activities, fun technical sessions, and social time for parents.

Julie Fuller fullerI am the wife of Russ, and a mom of 3 teens. We have been coming to CodeMash as a family since the first year. That was back when the kids were just toddlers and we walked the waterpark seeking other codemash widows.  In my life before kids, I was a Recreational Therapist, working at a hospital physical rehab unit.  Since then, I have become a mini-van driving taxi driver for any and all kids’ sports and activities including but not limited to baseball, softball, bowling, marching band, skiing, youth group, clubs and on and on… What do I do for me?  Coffee! It has been exciting to be a part of KidzMash and watch my children go from back of the room daisy-pickers to full-participants and helpers!


Courtney Eaton Eaton

Wearer of many hats. Wife to Michael Eaton (and to you that know him well, know that definitely deserves a hat of its own), mother to two great kids, Katie and Jacob, who of course are growing up way to fast, teacher (both to 4 yr olds and my own children), a co-founder of the Children’s Museum of Branch County and now, support staff for Kidzmash.  For the past eight years, I have been the co-Director and teacher for three and four year olds (4 year olds being my favorite but don’t tell anyone).  I tend to gravitate towards kids in any situation; you could say I tend to fit right in.  I love seeing the smiles on their faces and hearing them laugh makes my day!   I currently live in Coldwater, MI with my wonderful husband, Michael, our two children, Katie and Jacob, my mother-in-law, our bunny, Snowball, and a dwarf hamster named Chloe.


Session Committee

For CodeMash 2016, there were over 1,000 amazing session proposals submitted, and that is a number that continues to grow every year. One of the biggest challenges with CodeMash is deciding which proposals to accept. This herculean task falls to the Session Committee Members:
