I actually gave the leader of our classes and uke group, Cali Rose of The CC Strummers an acknowledgment in other thread yesterday, but I'll be glad to do so again.
This is a quote from Lori on that thread, "A good teacher will go through it slowly the first time, and address any helpful tips for making the fingering efficient, and any special strum patterns. The second time through the song, still playing slowly, and the instructor possibly calling out instructions for the tricky parts." Which is what Cali does to a tee.
Cali also has a great sense of humor, which makes our twice a week classes so much fun to attend. Her personal attention and her devotion also creates an atmosphere of camaraderie, especially with the twice a year pot luck parties she throws.
