I am delighted to have joined Keston Primary School as Headteacher in spring 2026. Keston holds personal significance for me, having spent part of my childhood in the area. My family and I remain closely connected to the local community, and it is a privilege to now serve it professionally. The school’s motto, Respect, Believe, Achieve, strongly reflects my own values as a leader, and I am committed to ensuring every child feels known, supported, and inspired to succeed. I bring leadership experience from both the state and independent sectors, most recently as Deputy Headteacher at a local school, with a clear focus on high expectations, strong relationships, and values‑led improvement.
I believe that every child deserves the very best we can offer and that strong relationships are the foundation of a successful school. My focus is to lead Keston with integrity and a clear focus on what is best for our pupils.
After 16 years working in teaching and school leadership, I was proud to take on the role of Headteacher at Chipstead Valley Primary School in September 2025. It is a privilege to play a part in shaping children’s education and development; work I believe is vital in helping them thrive in the future.
Throughout my career, I have always championed a balance between setting high expectations while creating a nurturing, inclusive environment where every child feels a sense of belonging. I have a strong interest in cognitive science and pedagogy, and I am passionate about using research-informed approaches to continually improve how we teach and how children learn.
As a mother to two primary-aged children myself, I understand how important it is to build a school culture that supports both academic success and personal growth. I am committed to leading with integrity, kindness and a relentless focus on securing the best outcomes for every child.
I was delighted to be appointed to the role of Head of School and am extremely proud to lead Beecholme.
My life and education values are in line with those at Beecholme and these are very much driven by my commitment to inclusivity. We will achieve inclusivity by ensuring that all children have the same opportunities to succeed in school and beyond, through an inspiring curriculum and by promoting a love for learning.
I enjoy all aspects of school life and love working collaboratively with children, families and the wider community. When I am not busy working with the children at school, I am busy at home with my twin boys who are 11 and who are my proudest achievement yet!
I began teaching in 1990, and have held leadership roles in a five-form middle school and a one-form primary with a nursery. I became Head at New Valley (then Wattenden) in January 2013, and since then I have been proud to lead the school through a time of enormous change and great progress.
Working in education - trying to improve the real lives of real people - there are good days and bad days...but never pointless days.
My teenage daughter is the most important thing in my life; when I’m not with her, you might find me walking up hills or playing records.
I joined Wattenden Primary School (now New Valley) as its Deputy Head Teacher, moving back into a school setting from a local authority role as a DfE consultant and maths advisory teacher. Since then, alongside class based teaching and leadership positions in my own school and on secondment, I have been an advanced skills teacher, NCETM specialist teacher of mathematics and TRG lead for Thames Maths Hub. These roles have enabled me to work across many diverse school settings and with a number of very talented and inspirational educationalists.
My passion is teaching and learning and I have a firm belief in every child’s right to a high quality, all-round education. I am committed to developing and strengthening the PACE Maths and English teams, and through curriculum development, CPD and collaborative working, to empowering all teaching staff to secure the best outcomes for the pupils of PACE Academy Trust.
