Native spanish speaker tutor (south america) for university and high school students

Hi, my name is Mariela, a 30 years old Ph.D. candidate in marketing. From the past year I've been tutoring my undergraduate and master colleagues, and I've also taught Management Information systems applied to business to undergraduate students (teaching assistant) and Dongbei University of Finance and Economics. My students and colleagues tell me I'm quite good at explaining and teaching to others, I am eager to apply that experience to Spanish instruction.
