Any teachers offering lessons in the Portland area? Let me know!
I am not from Portland, I’m east coaster, but, I came across this site while surfing. You might inquire there in with members who can recommend someone. Check their calendar as it has various events listed. Good luck.

And there is always Skype lessons thru the internet.
Have you tried getting in touch with Hanz Araki? I’m curious if he occasionally teaches or if he’s just too busy performing all the time.
Brenda Scearcy--brendascearcy@hevanet.com is an excellent penny whistle teacher in Portland!
+1 for Brenda Scearcy. She has flexible lesson times and has current openings. Highly recommended by others in the area.
