I was an executive editor for 10 years. Before that I was an senior editor, junior editor and an assistant editor. As a manager I led a group of historians and teachers in the areas of Social Studies and Civic Education. I directed several elementary, middle school and high school textbooks projects that consisted of the elaboration of the textbooks, teacher’s books, complementary printed material and in digital format. I managed the process from the initial preparation of the dynamics of the book (color, font, sections ...) until it is sent to print or access the web platform. I also trained and guided the staff in order to make them independent publishers, guaranteeing the quality of the products. I looked for authors and external collaborators to evaluate the material as well as for the writing of contents and activities. I worked with the sales promoters to develop product sales strategies. I supervised the preparation of illustrations. I trained teachers to use the textbook and complementary resources. Currently, in Costa Rica the books of elementary and middle school are in sale. This is the last project that I directed. The name of the collection is Crecemos Juntos and is for private schools.
