The Thatcher Book Parent Teacher Organization is a dedicated group of parents and teachers, devoted to enriching the lives of our students. The PTO offers community events, school mini-grants, and enrichment programs to our students and parents at Thatcher Brook Primary School.  These include: the Four Winds Nature Program; Field Trips to local farms, businesses, and the Flynn Performing Arts; Ice Cream Social; Family Ice Skating; Family Swimming; Student Cross-Country Ski Program; Teacher Appreciation; and other activities that bring the families of the 400+ students at TBPS together to learn and celebrate our community.
