John Quinn was accused of misconduct by a former student at Fenwick High School.
"Fenwick immediately launched an independent third-party investigation when allegations of misconduct were brought to our attention in December 2021 by a Fenwick alumna," the school said in a letter when an investigation was initially announced.
Former student Helen Quinn-Pasin accused the teacher of wrapping his arms around her, pressing his cheeks and lips against her face and asking about her love life.
In a statement released on Quinn's behalf, he denied wrongdoing and said he is deeply disappointed he won't be able to continue his teaching career at Fenwick.
Fenwick officials said in a statement they made the decision not to renew Quinn's contract after an independent investigation.
