About Me

I taught math and physics in an Indiana public high school for twenty years. I created GraphFree because I couldn’t find any other graphing program that did everything I thought math teachers needed. I used it often in my own teaching, and several revisions later, I hope it can help support my family now that I’m no longer teaching.

This help request form goes straight to me, and it’s not just for help requests. Feature requests and other feedback are welcome too.
