Michael Giambelluca, a longtime Catholic educator who served as principal of Jesuit High School in New Orleans for a dozen years, will take over as president of De La Salle High School in July, according to letters distributed to the school community.

Giambelluca is now in his second year as principal of Christ the King Parish School in Terrytown. Before that, he spent more than a decade as Jesuit’s principal until he left in 2013 to become the first layperson to serve as president of Creighton Preparatory School, a Jesuit high school in Omaha, Nebraska. He resigned after a year.

De La Salle is a coed Catholic high school on St. Charles Avenue in New Orleans. Its last permanent president, Michael Guillot, died in April after a battle with melanoma. Interim President Myles Seghers is retiring.

Giambelluca has been a Catholic school administrator for more than half of his 26-year education career, which makes him a good fit for De La Salle, Seghers said in a letter.

“I am looking forward to working with Mr. Giambelluca during this transition period, and I ask that the De La Salle family join me in welcoming him,” Seghers said.

In a separate letter, Giambelluca said he was “grateful, humbled, honored and excited” to be De La Salle’s next president. He also thanked the Rev. Michael Nam Nguyen, pastor of Christ the King Parish, and that school’s community.

It was not clear Thursday who will replace Giambelluca at Christ the King. The Archdiocese of New Orleans, which oversees Roman Catholic schools in the New Orleans area, typically announces principal and president decisions the summer before a new academic year.

Giambelluca will begin his job at De La Salle on July 15.
