Dear Sir or Madam,

I am writing to raise a serious concern about the gymnastics coach who has recently taken charge of my daughter's training. My daughter, who is nine years old, has been enrolled at your club since she was four, and for all five of those years she trained under Lena, who sadly became seriously ill and had to give up coaching a short while ago. This news dismayed both my daughter and me, because Lena was a truly exceptional instructor, and we sincerely hope she recovers soon.
