I had the pleasure of working with Tanyel in the Financial Services industry, for 18 months (to early 2018).
Tanyel has an engaging personality and is very good at explaining complicated things, in a nice and easy to understand way.
I didn't meet anyone who didn't get along with, and enjoy working with Tanyel, throughout our working relationship. I would happily have her represent our area, to other parts of the business as well as externally.
I also found out just how good Tanyel was with children, when she looked after mine for hours on end, at a work social event. They still wonder when she is returning.
I have no hesitation in recommending Tanyel, as a teacher / tutor.
