O’Block Books has been dedicated to publishing and selling affordable, high-quality teaching resources since 2002. The company is owned by Tina O’Block, an experienced teacher with a Master’s Degree in Curriculum and Instruction and a Bachelors’ Degree in Elementary Education. In 2002 while teaching kindergarten Tina realized that the educational supply market lacked a quality curriculum for preschool/kindergarten that addressed the various needs and ability levels of all students. She ended up creating one of her own and after many requests from fellow teachers and parents for her ideas and materials, she decided to author Now I Know My ABCs and a Whole Lot More. It quickly became a valued resource for early childhood educators and customers repeatedly asked her for more materials. This sparked her to start a company that was dedicated to high-quality early childhood educational materials at affordable prices.
