Don Johnston, MS
Don didn’t read his first book until the 9th grade after he was inspired by a very special teacher. He learned to make “movies in his mind” which was the key to his learning. This was influential in the visual supports in Readtopia. Don has wanted to bring visual learning to other students his whole life. Now it’s a reality! Don made Readtopia his full-time passion, driving the development forward. He embedded himself in many Readtopia videos, talking directly to students on-location from around the world!
Jerry Stemach, MS, CCC-SLP
Jerry Stemach is a language and literacy specialist who has focused his career on students with language-based reading disorders. 20 years ago, Jerry and Don co-founded the Start-to-Finish library to provide older readers access to age-respectful books supported by technology. Those same books anchor each Readtopia unit. Jerry levels the graphic novels and the text type lessons that accompany them. When he authors a book, he insists on traveling to the country where the story takes place.
