Dana Center Role

Katey oversees the delivery of the Center’s services for K–12 educators and administrators. In this role, she provides leadership, guidance, and continuity across all K–12 products and services offered by the Center in an effort to ensure greater equity in our education system. Katey consults with districts and leads projects across the United States, developing and facilitating discussions and professional learning opportunities with teachers as well as school-, district-, and state-level leaders. In addition, she leads the Urban Mathematics Leadership Network, which brings together math leaders from large urban districts from across the country to create common solutions to common problems.

Katey leads the U.S. Department of Defense Education Activity’s System-wide PK–12 Mathematics Professional Learning Initiative, a project providing a series of aligned, coherent, and interdependent professional development sessions that build the capacity of DoDEA educators to ensure that all students graduate college and career ready in math. She also leads the Mentor Teacher and Content Leader Initiative with the Louisiana Department of Education, a project that provides professional learning to educators across the state while building capacity for leadership within districts and the state.

Her prior work includes instructional leadership roles at the campus level as well as leadership roles at the district level, including serving five years as the mathematics coordinator for a diverse district in Texas. Katey has developed and delivered professional development for educators at the state and national levels.
