Tuitional Certified Tutor · Certified English Language Tutor | CELTA & TEFL Qualified
7+ years experience • Flexible scheduling
Diana Gisairo teaches English to learners across the world, backed by a CELTA from Cambridge Assessment English and a full TEFL qualification. Her degree in Communication and Journalism, together with a diploma in primary education, shaped a teacher who treats language as something to be used rather than recited. Over 7 years she has worked with students of every age and starting point on international online platforms.
What sets her apart is precision. She listens for the specific habit holding a student back, a hesitant sentence opening, a weak paragraph plan, a vowel sound that never quite lands, and builds the lesson around it. Her instruction has produced a documented 15-20% improvement in overall English performance. Lessons stay conversational, and progress is reported openly so families can see it.
