I am professional English language teacher with 20 years of experience and a Serbian native. Either you need English for school or business purposes and you need to speak/understand it at idiomatic level I can help ! Also my services are for those who would love to learn Serbian/Bosnian/Croatian to be able to understand their friends and family and be familiar with the language and customs. I devised my own interactive teaching material that can be used on iphone, ipad or computer. Hundereds of satisfied students are my best recommendation.
