Madam L
My driving teacher was Sina ('Sean'). He was great -- not only was he patient but he knew a lot and was genuinely interested in and enthusiastic about his job. He remembered things that had happened in previous lessons, and whenever I had trouble with something he always had a way of explaining it which made sense. Also, unlike a lot of other driving instructors, he was professional as in he was not nosey and intrusive about my personal life and did not himself talk about, nor did he expect me to talk about, things that weren't related to driving. On a more minor note, he was very rarely early and was usually more or less exactly on time, however that is just a personal preference which may not apply to all students. Another thing I liked was the option to pay by card rather than cash all the time.
Sina is a very calm and relaxed person -- nothing fazes him. I really wish everyone in this field was like him, especially seeing as there are so many incompetent charlatans around in the crazy world of driving instruction. If I am ever in a position to recommend a driving teacher I will gladly mention Sina.
