Principal's Message

It is both a privilege an honor to be the Principal of Greenwich High School and to welcome you all to our website. 

Prior to returning to this great institution, I served as the Interim Superintendent of the Greenwich Public Schools and as the Principal of Eastern Middle School. However, the majority of my career (thirty two years) has been spent at the high school where I have held a number of administrative, teaching and coaching positions. I last served as Interim Headmaster in the spring of 1999 when Dr. Eileen Petruzillo retired mid-year. Since that time Greenwich High School has evolved into one of the preeminent high schools in our state and country.

Our staff, students and parents have worked together in a highly collaborative manner to ensure that we maintain open lines of communication. Our website serves as just one of the many components of our communication network. We feel that everything you need to know about our great school is located on this site. However, if you are having difficulty navigating it, please do not hesitate to ask for assistance.

I am looking forward to having a great year at the high school as we continue to set the standard for excellence in public education.
