Clare Landrigan is a staff developer who is still a teacher at heart. She began working with Tammy Mulligan twenty-four years ago co-teaching in an integrated first and second-grade classroom at the Eliot Pearson Children’s School in Medford, Massachusetts. Clare and Tammy now lead a private staff development business, Teachers for Teachers, and spend their days partnering with school systems to implement best practices in the field of literacy. They believe that effective professional development includes side by side teaching; analysis of student work; mutual trust; respect; and a good dose of laughter. You can find them on Twitter as @ClareandTammy and online at www.teachersforteachers.net where they blog about books and the art of teaching.
