She made an assignment of DELE (Diploma de Espanol…) for two years at that University. At the beginning of 2016 she moved to Cabo San Lucas, Mexico where she currently resides. She loves to teach vocabulary and grammar. She is also interested in helping to integrate expatriates into the new community, learning the language of the new country is the most effective way for such purposes, as it is a communication tool, but also involves culture and worldview. Flavia is enthusiastic to be collaborating with the Full Immersion in the Cabos, with the FD Languages Academy. It is a fun way to learn effectively where the students will see interesting and incredible places while they continue learning more of the Spanish language. Flavia’s teaching style is relaxed, apart from imparting the formal contents, she considers that having a conversation with the students is when the more they unravel and practice the language better. She is a patient and friendly teacher dedicated to helping new residents overcome barriers in their Spanish and feel comfortable communicating fluently to feel part of the community. In her free time she likes to read, watch series, movies, watch plays and attend recitals. She is interested in traveling and meeting new places and people while she lives in paradise.
