Learning English with a native speaker is always better than learning it with a non-native. You can quickly improve your speaking skills, pronunciation and English grammar.
Our lessons are concentrated on your interests (business, technical) and weaknesses to improve your language skills. Having lessons here will be fun, interesting and will improve your English skills.
Having Private lessons are better as they are more focused on what you want out of the language. People who have learnt in groups often get frustrated as they don't cover subjects they are interested in and the courses can take longer due to the fact that they're not getting one to one attention.
