I was instantly struck by Leonardo’s captivating manner of teaching. He helped me transition from IB to university and provided remarkable emotional support in a turbulent period of my life. He always leaves me inspired and encouraged.

I have supervised Leonardo during his PhD at ETH Zurich, where he proved himself as a very talented scientist and an excellent teacher. I highly recommend him as an admissions tutor for Cambridge and Oxford as well as other universities.
