Lessons of conversation / grammar / DELE y SIELE preparation

My name is Juan, I am Argentinian and I live in Buenos Aires. I have a University Diploma in Teaching Spanish as a Second and Foreign Language and I have a double university diploma since I graduated from two universities. I have 15 years of experience, both in the formal and informal spheres. I specialize in conversation, diction and pronunciation of Spanish. In addition, I am a candidate trainer for the SIELE and DELE international exams. I have experience teaching Spanish lessons to students from all over the world and of all ages (children, teenagers and adults). Lessons are only online.
