Ms. Melissa Hall — Assistant Principal

Assistant Principal

“The most effective teachers and school leaders do not think of what they do as a job, but rather as a calling or a cause. It takes collective passion and perseverance to make a great school.”

I am incredibly honored and excited to be a part of The Greene School Community! 

I am a native Rhode Islander with fifteen years of public high school teaching experience. Certifications in both Special Education and Mathematics have given me a diverse understanding of the various types of learners, and the strategies needed to allow every student to reach his/her full potential. In addition to teaching, I have been an active member of school leadership teams, participated in curriculum and assessment development, and mentored new teachers. I realize it takes an entire school community- including teachers, staff, students, parents, and community members all working towards the vision and mission of a school to make a school great.

I love the environmental and 21st Century skill-set focus of The Greene School, and think our students have an amazing opportunity here to enrich their education through local and global stewardship. The passion and dedication of the entire Greene School community is already apparent to me, and cannot wait to work with everyone as we all strive to make TGS the best it can be.

Mr. Brendan Haggerty — Math/Science Instructional Guide/Chemistry Teacher

Math/Science Instructional Guide/Chemistry Teacher

"I hold a deep belief that critical thought is the most indispensable quality of a self-governing society, and therefore public education must be recognized as the heart of a functioning democracy."

Mr. Brendan Haggerty is one of two science teachers at The Greene School, where he teaches chemistry. Armed with a Bachelor’s degree in environmental studies and education, and a personality that inspires a thirst for learning, Mr. Haggerty is undoubtedly one of The Greene School’s strongest advocates of expeditionary learning. Of specific interest is his own training and background, which has resulted in his firm belief in experiential education; a process where students are immersed in direct learning through field work – and these learning experiences relate back to the classroom experience –a learning process that students gain exposure to through the expeditionary learning philosophy at The Greene School.

Before joining The Greene School, Mr. Haggerty taught at an expeditionary learning school in Arizona, but his desire to return to his New England roots, and its diverse ecosystems and landscapes led him to embrace the unique opportunity to serve students in the State of Rhode Island, where The Greene School is the first and only expeditionary learning, chartered public high school.

Entering his seventh year of teaching, Mr. Haggerty is also certified to teach earth science and chemistry. In addition to regular classroom activities, Mr. Haggerty is the senior project coordinator at The Greene School.
