Andres A. Alonso began his tenure as professor of practice at the Harvard Graduate School of Education, where he received his doctorate as part of the former Urban Superintendents Program. Alonso teaches a course on urban and systemic reform, and contributes to leadership programs such as the Doctorate in Educational Leadership (Ed.L.D.) and the Public Education Leadership Project (PELP). Alonso served as CEO of Baltimore City Public Schools (City Schools) for six years, where he led a reform effort marked by a rebalancing of authority and responsibility among stakeholders, the building of a coalition in support of City Schools, leading edge labor contracts, and a focus on individual students and teaching and learning that yielded marked improvement in achievement and climate data across all levels, the first increases in enrollment in 40 years, and widespread political and ground root support for what have been divisive reform strategies in other districts. Before Baltimore, he was chief of staff and then deputy chancellor for Teaching and learning during the first phase of New York's Children First reforms. He spent 12 years as a teacher of English Language Learners and students with disabilities in Newark, N.J.
