I do not teach piano. For that, pianist and teacher Jozua Dieleman is the man to see in this region.
He teaches in Drielanden, a district of Harderwijk, at Biezenplein 1. That is about fifteen minutes from Ermelo.
Why it is listed here
I am asked fairly often whether I also teach piano. I do not, but I do know where you will be in good hands.
