New Assistant Principal Appointed At Greenwich Elementary School

GREENWICH, CT — Greenwich Public Schools Superintendent Dr. Toni Jones this week announced the appointment of Larissa Weir as assistant principal of Riverside School, effective immediately.

Weir will work alongside Principal Mary Dolan Collette, who was appointed principal after serving for three years as the school's assistant principal.

"Greenwich Public Schools continues to attract the best educators and administrators the region has to offer," Jones said in an announcement.

"Mrs. Larissa Weir’s strong education background and passion for student-centered intervention is very impressive and will be a perfect fit for Riverside School. Not only is she a very talented math and science educator, but her experience as an interventionist and building level support, to help all students find success, will be a major asset," Jones added. "This past year, she partnered closely with primary teachers to successfully roll out and implement a new academic curriculum."

Weir joins GPS from Stamford Public Schools, where she most recently served as interim assistant principal at Julia A. Stark Elementary School during the 2025-26 school year.

Before that, she served at Stamford's Westover Magnet School, first as teacher leader for student support and later as a multi-tiered systems of support (MTSS) coach.

Her 15 years of experience in education also include serving as a seventh and eighth grade science teacher at New Haven Public Schools' Roberto Clemente Leadership Academy as a Teach for America Connecticut corps member, and as a magnet resource teacher and math coach at New Haven's John S. Martinez Sea & Sky STEM Magnet School.

"Driven by a passion for educational equity and student-centered leadership, I join the Riverside community dedicated to the growth of every child," Weir said in an announcement. "Working alongside Principal Dolan Collette, my goal is to foster collaborative partnerships with our teachers and families that empower every Red Hawk to thrive. My priority is ensuring our school remains a safe, vibrant space of academic excellence for all students."

"Mrs. Weir brings a wealth of experience to our school having served as a classroom teacher, MTSS coordinator, and interim assistant principal," Dolan Collette said. "She is committed to maintaining high expectations for all students while fostering a strong culture of belonging, and I know her enthusiasm and expertise will be a tremendous asset to our school community."

Weir earned a bachelor's degree in zoology and gerontology from Miami (Ohio) University and a master's degree in teacher leadership and a sixth-year diploma in educational leadership from Quinnipiac University.
