Dr. Arreola recently served as the Executive Director of Leadership Development in Houston, where she led the implementation of the district’s leadership academies and worked with cross-functional teams to support Mission-Driven Leadership. In this role, Dr. Arreola collaborated with universities, non-profit organizations, community members, and business partners to secure that support for the district's five strategic priorities.

Dr. Arreola’s transformational leadership led to six Improvement Required schools to Met Standard accountability rating by Texas Education Agency (TEA) over a two-year period after being low-performing for as long as ten consecutive years. In an effort to build a bench of ready leaders to transition into campus leadership roles as they became available, Dr.  Arreola secured the TEA Principal Residency Grant with an award amount close to one million dollars to be allocated towards full college tuition for aspiring school leaders to earn  their Master’s Degree in Administration and Supervision while serving in a full-time residency program.
