The Mesa Unified School District hired three new leaders Tuesday evening.
Delfino Aleman will take over as the district's associate superintendent on July 1.
He has a doctorate degree from the University of Texas at Austin. He will replace Mike Cowan, who will take over as the district's superintendent.
Current Superintendent Debra Duvall is retiring at the end of June following a nine-year tenure.
Aleman is the superintendent in residence for the National Center for Urban School Transformation in San Diego. Previously, he was an area superintendent for the San Diego Unified School District and an associate superintendent in the Isaac Elementary School District in Phoenix.
Bruce Cox will take over as the west area assistant superintendent, replacing Ken Salas, who will retire at the end of June.
Cox has a master's degree from Northern Arizona University and is the current principal of Mesa's Smith Junior High School. He has worked in the district since 1987 and has been a principal since 1996.
Holly Williams will be the assistant superintendent for special education, a newly created position replacing the previous position of assistant superintendent for student services.
Williams has a master's degree from NAU and is the current principal at Mesa's Skyline High School.
Governing board president Mike Hughes praised Cowan for putting together a "well-rounded team."
"In my opinion it speaks volumes for what we're doing and what we need," Hughes said. "He pulled in a well-rounded team that has not only views of what's established in Mesa but somebody who can have a fresh set of eyes."
The district is facing several challenges with declining enrollment and expected budget cuts from the state. Cowan is currently leading a community group to help develop new vision and mission statements for the 69,000-student district with a hope it will create new goals and ideas.
