Meet our Faculty

Julia Sniffen

High School Principal

Mrs. Sniffen has taught and supported students at Haldane for over 20 years. From multi-grade elementary teacher, to leadership roles in the middle school and high school, she has come to know almost every family in Cold Spring. Her focus is on the whole child – the academic, social, and emotional needs of each and every student. When not on the Haldane campus, Mrs. Sniffen enjoys the outdoors, musicals, and sports with her husband, Jeff, and children, William and Caroline. Cold Spring is Mrs. Sniffen’s second home and she loves being part of this community.

Michelle Cordaro

Teacher, History Club Advisor
Social Studies
This is Mrs. Cordaro’s 7th year teaching Global History at Haldane High School. She is very happy and considers herself quite fortunate to be able to come back and teach at the same school she grew up in. Mrs. Cordaro’s favorite activities include spending time with her family, reading a good history book, and visiting Disney World as many times as she can. She also loves telling jokes; unfortunately, people don’t always love laughing at them. Mrs. Cordaro believes in the value of teaching history, as she thinks that by discussing our past, we can work together to help move our society forward in a positive direction.
