Welcome, Groton Families

From the Deans

Dear Parents,

Welcome to Groton School. As the deans of students, our primary role is to guide your children and help them find their most productive paths at Groton. We do our best to get to know each of them, which really is possible in a school of our size.

On these parent pages, you’ll find lots of useful information, from important phone numbers to summer reading lists. While you’ll find much of what you need right here, on these public parent pages, you will need to sign in to myGroton, the password-protected portion of our website, for grades and comments, the School handbook, an expanded calendar, and various notices throughout the year.

We hope you’ll spend some time with our Frequently Asked Questions. There you’ll find information on everything from our dress code to vacation planning, from laundry to textbook orders.

If you are ever concerned about your student or have questions, please don’t hesitate to reach out, either to your child’s advisor or to the Deans’ Office. We’re here to help.
