Mr. Liam O'Brien

Hello, my name is Liam O'Brien.

This will be my seventh year teaching at Herricks High School. I graduated from Hofstra University with a Master of Science in Education back in 2012, and completed their Advanced Certificate Program in Educational Leadership in 2017. Prior to becoming a teacher I was an accountant for two New York based businesses; a pharmaceutical manufacturer that was eventually acquired by Humanwell Puracap, and one of the leading home health care companies in the United States.
