As founder of the business Sara's qualifications include an honours degree in Mathematics and Membership of the Institute of Actuaries (1994). Sara has been tutoring maths (up to A level) since 2004 and also tutors for the 11+ Entrance Exam. With an excellent reputation for student success, a warm and personable approach and a resultant continual flood of referrals and recommendations, Sara quickly found that the demand for tuition outstripped her ability to provide. In 2008 she launched Chatterton Tuition with just a handful of tutors on the books. Chatterton Tuition then saw a period of rapid growth and success resulting in over 150 tutors joining the Teaching Team. Chatterton Tuition became a limited company in November 2013 and Sara's teacher-husband Phil joined the team.

Connor joined the team in April 2026. His qualifications include a First Class Honours in Primary Education from Durham University and a NPQ in Senior Leadership. With over 10 years of experience as a primary teacher, Connor has specialised in leading SATs, Maths and working with children with SEND. Having successfully transitioned into secondary maths teaching, he now brings a wealth of expertise to his tutoring. Connor provides tuition for the 11+ and offers specialist maths tuition for all age groups, including GCSE and A-Level.
