From Newsday: The Academy of St. Joseph in Brentwood is closing due to lack of enrollment.
"The only all-girls Catholic high school in Suffolk County, a hidden gem housed in majestic buildings on a lush 211-acre campus in Brentwood, is closing its doors. The Academy of St. Joseph, whose history dates back 153 years, lacks the students and money to make running it financially feasible, Sisters of St. Joseph of Brentwood president Sister Jean Amore said yesterday. The school will shut down in June."
This is sad news but common around the Northeast, with declining enrollment and escalating costs it is just too difficult to keep many Catholic schools open. Of course, many religious communities stopped focusing on education and orthodoxy in the 60's and 70's and that too hurt their ability to remain vital and growing, in turn affecting their apostolates, so that also has played a role.
