Our team

Our team is composed of world-class professionals from a variety of backgrounds, including education, private sector, civil service, and NGOs. We are a community of learners devoted to LEAF’s cause of providing the best education possible to individuals of character, regardless of their economic background. Apart from teaching their own subject, tutors take upon themselves the role of dorm-parents, mentors, advisors, sport trainers, and organizers of co-curricular activities.

#teacher #CES #advisor #safeguarding

At LEAF Academy she teaches Writing and Rhetoric as well as AP English Literature and Composition. English became Lenka’s passion upon having lived in London for almost five years. She went on to study English Language and Literature at Comenius University and later combined it with a business perspective, earning her MBA at the City University of Seattle. Lenka has spent her whole working career helping others become better and feel better about themselves whether by speaking English more fluently or finding out a little more about their own dreams in other subjects that she has taught at universities in Slovakia and abroad (Professional Business Communication, Environmental Science, Sustainable Development, Critical Thinking). She has lectured in Finland, Lithuania and taught Chinese students how to think critically at a university in Prague. She loves organizing outdoor events with an environmental twist. She believes in forming a bond with students way beyond the classroom as this transforms the education process into a lifelong experience. Her unconventional teaching methods and assignments have earned her different awards, but her best award is knowing her former students found her lessons meaningful for their future and helped them develop as a person.

Matej Sapák

#teacher #CES

Matej’s twin passions for exploration and stories have guided him for most of his life. A boy scout since the age of ten, Matej learned to love the outdoors and treasure friendships formed on a long hike or around a campfire. His curiosity and desire to understand how things work, and to learn new stories, also attracted him to try his hand at debating. Eventually, he would use his debating experience to take two Slovak teams to the finals of international debate tournaments, and one of them to victory. That same curiosity led him to a boarding school in England, an International Baccalaureate school in Bratislava, to study Math at Harvard College and finally Law at Harvard Law school. Through it all, Matej became more and more interested in the stories of the people he studied and worked with, and he came to believe that the future of his country lies in the stories of its talented people. Seeking to give other young people the same opportunities he has had, after working with McKinsey & Company, he spent two years in public service helping to write a national strategy for knowledge economy, and then joined LEAF, a Slovak non-profit dedicated to helping talented young people live inspiring stories of leadership.

Matej greatly enjoys getting to know many more talented young Central Europeans and help them kindle their own curiosity and develop their own stories.
