Multi-award winning Head of Geography and Cambridge graduate. Department results: Top 2% nationally for GCSE progress. Highest % of A/A* grades at A Level among boys' grammar schools in recent years.

Dion's passion for the subject, teaching experience, and knowledge of the course were all invaluable when I chose him to tutor my daughter through her Geography A Level. He quickly boosted my daughter's confidence and progress. Thanks to his tutoring, my daughter's grades skyrocketed. She achieved an A* and she is now very happy at university. I was also impressed with Dion's knowledge of the latest educational research on learning and memory skills. So much so that I booked him to do a few sessions with my son on how best to revise for his GCSEs. My son is rather lazy but Dion's impact was instant. My son became much more motivated and his exam results exceeded all expectations. Dion's manner with students is excellent and we cannot thank him enough for the positive impact he has had.
