After 36 years of shaping hearts and minds at O'Gorman, it's time to say thank you to someone who has meant so much to so many — our principal, Mrs. Mahoney. 💙
Mrs. Mahoney joined O'Gorman as an English teacher in 1990 and leaves us this year as our principal — but more than any title, she leaves as someone who made this school what it is today.
