About me

Hi, I’m Sian—the founder of On the Mark and a passionate English tutor who genuinely loves helping students grow in confidence, skill, and self-belief.

I’ve spent years supporting students of all abilities to navigate the ups and downs of English—from structuring their first analytical essay to preparing for final exams. What I love most is seeing the individual progress each student makes—not just academically, but watching their confidence soar.

Since becoming a mum myself, my perspective has completely changed. I understand more than ever how much parents want to see their children feel supported, see them thrive and most importantly, be proud of their own achievements. That’s why I’ve made it my mission to dedicate my time and energy to making a real difference—not just for students, but for the families who care about them.

Whether I’m marking an essay, running a group class, or creating resources, everything I do at On the Mark is built around care, clarity, and helping each student feel seen and supported.

I'm thrilled that you're here!
