I would like to thank Mr Raisi for organising such an interesting Business English course for me. I am the CEO of a company in Milan, Italy, and Hossein helped me to improve my Business English.

The course was tailor-made based on my needs and I felt that I gained valuable and useful language structures in order to communicate more effectively in the workplace.

My tutor, Mr Hossein Raisi, is very well organised, professional, creative, interactive and approachable. He shares his knowledge and experience with the students and is practical in his approach. In fact, the course gave me not only the language but also new insights and business ideas which I am now using. I would highly recommend ESPbase’s Business English course to you.”

My name is Tian Wen. I’m from China. I arrived in the UK in April [2015]. Before that, I was working for a real estate company as a sales manager. I came to OLC to improve my English, especially for Business English. I finished my five months’ course one month ago. The time I spent here was amazing.
...every week I had five hours of Business English in the afternoon. My Business English teacher was Mr Hossein Raisi. In his lesson I had the chance to interview the Principal of a College in Oxford, to listen to a Finance Manager sharing his working experience and to attend a lecture given by an expert from a security company as part of my Business English lessons.
Hossein also suggested that I took the BEC TEST (Business English Cambridge), which might be helpful for my work in the future. I took his advice and passed the Vantage level exam at the end of the term.

Mr. Hossein Raisi was my Aviation English teacher six years ago. My company sent us, air traffic controllers from Poland, to the Oxford Academy to help us with preparing to pass a newly-introduced exam ELPAC. I still remember the lessons with Mr. Hossein, so it's my pleasure to share my reflections in public.

I found those lessons very interesting. Our teacher was always well-prepared, kind and very patient. It was easily visible that he liked his job and knew the topic. He explained to us all the details connected to such an amazing phenomenon as the ability to let people fly.
I passed the ELPAC exam and so could continue my work. Thank you very much Mr. Hossein Raisi. I am sure you helped me and you will help all your students. With best regards for all aviation people.

Native Speaker vs. Non-Native Speaker

Native speakers and non-native speakers can both succeed as ESL teachers.

There has always been some controversy in the ESL community over the difference between having one or the other teach language courses. Obviously the situation varies from place to place but there are definitely pros and cons for both sides of this debate.
