English tutor for all ages and all levels

I am from the United States and my first language is English. I have a Bachelors degree in Political Science and I am currently working on my Master's degree in Education at the Freie Hochschule Universität in Stuttgart. I worked for six months at a middle school in the United States and I have done a one month internship with a third grade here in Germany. I have a good understanding of the basics of the English language and can go over sentence structures with beginners. I am also well read and can help to advance English vocabulary in business, politics, literature, and so forth with those who need to take their English skills to the next level.
