hi , I did not find Bernie on thumbtack, I have taken guitar lessons from him for a couple of months.
I was telling him how much I enjoy his lessons, much more than a past teacher .
He said if you you mean it go post a review ofer hear.
He explains concepts in a simple way which is easy to understand.
My playing and understang of music ha improved quite well ,,, not like my last teacher.
Also he keeps it lighthearted and not to stress.
good teacher I would recommend
