Mr. Michael Jonagan

Room Number 152

Biography: Before joining the Gateway Middle School team in July 2019, I taught for seven of the previous nine years and served as a City Year Americorps instructional coach for the remaining two. I have spent my entire career in grades 5-8 and wouldn't have it any other way! Middle school students are bright, funny, hardworking and unfailingly capable of growth. I live in and love St. Louis with my partner and our dogs and cat. You may see me running or trying to prune the unruly tomato plants in my backyard garden.
