Received via e-mail from Nils Hedberg Grimlund: 

“Claudinei has been teaching me and my son guitar for about two years. During this time he really managed to waken my son’s enthusiasm for playing the instrument, and managed to get me actually playing samba. 

He was always very kind and adjusted the lesson structure and content according to how we developed and was great at finding songs that we liked to play. 

He speaks Portuguese and some English. In the beginning my son did not speak much Portuguese, but it went very well anyway from the start. 

A warm recommendation! Phone/WA: +55 62 9319-9692”
