Updated at 1:52 p.m. with statements from the headmaster and the superintendent: 

Tony Ciccariello, the headmaster at Somerville High School, announced Monday night that he would resign at the end of the school year, said the district's coordinator of grants and information, Susana Hernandez Morgan. 

Ciccariello said in a statement on Thursday that he decided to resign because of his health. In the statement he also reflected upon his work at the high school. 

"The opportunity to serve the young adults of our community is without a doubt, the most rewarding career experience that I have enjoyed," he said. "My time as an educator in the Somerville Public Schools has been a constant reminder of all that is good about our city." 

Ciccariello's decision was announced publically at the School Committee's Nov. 7 regular meeting, along with other resignations within the district, Morgan said. 

The headmaster, a life-long Somerville resident, graduated from the high school in 1973, he told Somerville Patch in a video interview conducted this September in which he welcomed freshman and returning students to the school. 

Superintendent Tony Pierantozzi also released a statement about the headmaster's announcement. 

"Tony Ciccariello has been a mainstay in our community as a professional since 1977, and before 1977 as a student leader," Pierantozzi said. "While I am absolutely saddened to see him go, I respect and support his decision. It goes without saying that he will truly be missed."
