[5] In 1982, Saint Ann's School formally disaffiliated from the church, having been granted a charter from the Board of Regents of the State of New York.

In response, the school commissioned an independent investigation, which announced in 2019 that it had identified nineteen former St. Anne's teachers or staff who potentially engaged in inappropriate behavior or sexual misconduct with students, going back to the 1970s.

[16] In February 2021 an eighth grade St. Ann's student, Ellis Lariviere, committed suicide after being notified that he would not be permitted to continue at the school following the end of the year.

Two years later, in April 2023, Lariviere's parents filed suit against the school, its headmaster, and its board of trustees for wrongful death.

[19] It was revealed that Nguyen had previously been convicted of grand larceny, stealing more than $300,000 from an elderly couple he worked for, and that St. Ann’s had been aware of his criminal past when they hired him.

[20][21] The school maintains a list called The Growing Shelf, which documents all published community members.
