Meet our Admissions Officer

I’m originally from Finland, where I completed the IB Programme before pursuing further studies in Ireland. Over the years, I’ve developed strong hospitality values while working in Switzerland, the UK, and Portugal with renowned 5-star luxury hotels.

Now, as a proud mother of two boys and an expat living in Lisbon, Portugal, I deeply understand how crucial it is for parents to find the right school for their children. I’m truly passionate about supporting families on this important journey and ensuring a smooth and stress-free admissions process.
