Denise Eide

Founder and President, Logic of English
My interest in teaching reading and spelling began when my twin sons struggled to learn how to read. Through my research to help them, I realized that my previous training in how to teach reading was inadequate. As I learned and taught the phonograms and spelling rules, I understood the implications to all students learning to read and spell, and I wanted to make a difference.  I started the company, Logic of English®, wrote Uncovering the Logic of English, and began developing curriculum and presentations to share what I have learned with others.
