Every setting is built on their team

For the team at Muriel Green, daycare and teaching is much more than a job. We care deeply about children’s happiness and success. Our classrooms are joyful places to be, where children are engaged and teachers give praise and encouragement. We listen to parents and families, and work together with them to help children achieve their full potential.

Roots Leadership Team

Gemma Williamson

Executive Headteacher, Roots Federation

In 2010, she led the foundation stage at Laurence Haines primary school in Watford. In recognition of her impressive leadership, the local authority made her a Leading Teacher. In this role, she helped schools across the county improve their early years provision.

Gemma took the headship at Muriel Green Nursery in 2017. That same year, she achieved the National Special Educational Needs Co-ordinator Award.

She began working as a consultant to the headteachers at Oxhey Early Years in 2021. Here, she had the vision to collaborate with Heath Lane Nursery to improve all three settings, a vision which eventually led to co-founding the Roots Federation.

Gemma sits on the governing bodies of two maintained primary schools in Hertfordshire, keeping her up to date with educational practice beyond early years. She also sits on two boards representing the voice of maintained nursery schools.

I’m blessed to be part of such a wonderful, forward thinking team who are making a difference to children’s lives.”

Sue is adept at building high quality, trusting relationships with families, and supports new parents when they leave their children for the first time.

“It’s a pleasure to support and watch as the children settle in, making new friends and getting their first sense of community. I love the depth and breadth of our curriculum - how it keeps children engaged and excited to learn. It’s so rewarding to see children and staff succeed and achieve where they thought they couldn't.”
