Júlia Mattiassich

After completing her qualifications as a preschool teacher in Budapest, Ms Mattiassich left Hungary to see the world - and landed in Florida. While completing her degree in Mathematics and Economics at Florida Atlantic University, she began working in the financial sector. Meanwhile, she never lost her lifelong passion for teaching and started tutoring mathematics. It wasn’t long before Ms Mattiassich decided to fulfill her dream of becoming a teacher, starting her teaching career as a mathematics teacher at the A.D. Henderson School in Boca Raton, Florida. This experience has also led her back home to Budapest to join our school in 2012, where she really enjoys working in such an international environment.

Ms Mattiassich has recently moved back home to Budapest after living in the USA for half her life. She has always been a natural educator; whether it is tutoring Mathematics to children or teaching Hungarian Culture to adults in America. Her latest passion is yoga, which is another avenue where she can teach in her “free time”.
