The tutor
Every lesson one-to-one, built around the child.
Cathleen Sagisi has tutored for nearly a decade. Through ThatTutor, she teaches math, English and science from Key Stage 1 to GCSE, prepares children for 7+, 11+ and 13+ entrance exams, and supports children with special educational needs.
Every engagement is one-to-one. Families start with a consultation and a short trial lesson to check the fit, then agree a plan together. She teaches in person around Upminster, in east London, and online for families across the UK and abroad.
Her lessons mix classroom teaching with coaching, mentoring and neuro-linguistic programming. She puts a child’s wellbeing first and sees good grades as what follows from a confident, settled learner.
In 2026, ThatTutor moved into its own office. Cathleen has also created and trademarked her own approach, the T.U.T.O.R. Framework, which she plans to share through workshops, coaching and training.
Recognized by her profession
In 2023, The Tutors’ Association named Cathleen Professional Tutor of the Year and Best Online Tutor at the National Tutoring Awards. She now serves on the association’s board of directors.
Safeguarding comes first
Cathleen is ThatTutor’s Designated Safeguarding Lead. Her terms tell families that online lessons are recorded to protect their child, that they can opt out in writing, and that a parent or trusted adult should be nearby during lessons for under-18s.
Online, she also thinks about what a child can reach. When a lesson needs the web, she opens a shared browser in the Space and searches alongside her student. She can guide the research and step in if a result isn’t right for a child.
