In the years since they worked together as staff developers at Teachers College Reading and Writing Project, they have each gone on to found professional development organizations focused on literacy - Renee's on the west coast, Gravity's on the east coast. The constant in all their work is to model for teachers how to develop classroom communities of readers, writers, and thinkers that thrive on student choice and voice. They are co-authors of the books What Do I Teach Readers Tomorrow? Fiction and Nonfiction, which reflect the authors' work in schools, their conversations, and a friendship built upon thousands of miles of swimming, biking, running, and crossing triathlon finish lines together.
