We hired Dietmar to do at home swimming lessons with our 4-year old daughter and 1-year old son and with 3 other friends aged 3, 4 and 8. First of all, all the kids loved Dietmar! He was so patient with all of them and after just a couple of lessons all kids improved by a lot. Before the lessons, our daughter screamed when she got water in her face and now all she wants to do is dive and swim underwater. I still can’t believe he got her to do it. We had swimming lessons once a week, 10 weeks in a row. And now our daughter is able to swim all by herself, she doesn’t need any floating devices anymore and can swim like a little fish! I can highly recommend Dietmar and I am sure your kids will love him too!
