Thankful letter to teacher staff

Dear Sirs/ Madams, By this letter I would like to take a chance to thank the President of ULIS, the Director of RELO and all teachers for providing learners with the best series recordings based on American English Live. I really admire your team’s efforts to create enormous document storage with more choice of playlist topics that help learners to save time searching. I believe that all participants find the course informative and worthwhile while we work around the clock and therefore have little time for our professional training. By providing this opportunity for training, I believe the course help me further improve and develop my teaching methodology.
