Welcome to third-grade! My name is Mrs. Hannigan. I’m so happy to be your third-grade teacher for the 2025 - 2026 school year. This will begin my 5th year of teaching. Before starting as a full time teacher here at Bayview I taught in Manhattan. 

I just got married this summer and I was formerly Ms. Bergin! I live in East Islip where I was born and raised. I love reading books, watching movies, traveling, and cooking.
