Mr. Lisandro Malissia

Theater Technical Director, World Language--Spanish Instructor

Bio

Born and raised in Argentina, Lisandro grew up with a healthy respect for how to live in harmony with the land. He studied medicine at the University of Cordoba. While attending his internship, he realized his passion for music and made a career change into the world of sound and recording arts, leading him to open a recording studio and host his own radio program, as well as mix sound for a plethora of live venues. Lisandro’s passion for music and sound eventually led him to documentary film-making, which opened the doors to a fantastic journey to over 25 countries around the world. Next to music, his deepest passion is his family and his community, which is why he has chosen to work at The Thacher School—to be close to home and in the heart of a community that supports the development of its young people. In his spare time, he enjoys camping, swimming, live music and theatre, and any opportunity he gets to add new places to his extensive list of travels.
