About Us


Joseph Tabenkin - Creator

I founded Let's Diagram over 15 years ago, at a time when I was just beginning to learn software development and sentence diagramming. It fills me with such joy to see the thousands of people who use of Let's Diagram to learn and teach sentence diagramming today. In 2022, I decided to dedicate myself fully to my passion for education and left my job to concentrate on creating resources for educators. Below, you'll find some of the other projects I've been involved in, each designed to support and enrich educational experiences.
