Huntington High School has a new leader at its helm.

The school board promoted Assistant Principal Brenden Cusack on Monday evening to replace longtime Principal Carmela Leonardi, who is retiring this year. Cusack’s appointment is effective July 1.

Cusack, a Babylon resident entering his 20th year in education, has been employed at the district for three years. He was seated in the audience at the school board meeting on Monday night at the Jack Abrams STEM Magnet School, and upon his appointment, members of the audience, including his family, cheered and clapped — some offering a standing ovation.

In an interview after the meeting, Cusack said he was eager to continue working on improving academics in the Huntington school district. He also wants to offer more opportunities for students to step up and would like to “try to develop and increased sense of caring” within the community, he said.

“Huntington High School is an amazing school,” Cusack said. “And I think you can see from a distance, [from] the outpouring of help to others, and things like that, and that’s something I want to build on.”

In a statement on the school’s website, Superintendent Jim Polansky lauded Cusack’s appointment.

“Over the past several years, Mr. Cusack has become an integral part of a successful high school team,” he said. “He has earned the respect of his students, staff and colleagues. He brings a wealth of administrative and teaching experience to the position. The achievement and well-being of his students have always been his foremost priorities.”

Cusack is a 1995 graduate of SUNY New Paltz with a bachelor’s in education, according to the statement.

Cusack earned a master’s at CUNY-Queens College in 2002 in adolescent education/English 7-12.

He obtained a professional diploma in school administration and supervision at CUNY-Queens College in 2005. He recently participated in school leadership training at Harvard College.
