I have been one of Suzanne's guitar students for several years in an evening group lesson situation at a local high school. I like Suzanne's enthusiasm and creativity in a lesson environment. I also admire how quickly she can deconstruct a song and make it playable for the class. Suzanne does an excellent job of balancing learning new songs and teaching the theory behind them without slowing down the fun. Her students seem to quickly pick up the guitar and enjoy playing it almost from day one.
I especially like that there is "no fault" if an adult student has trouble finding time to practice between lessons. Of course, without practice, it is hard to improve quickly.
Sometimes we work on a song that isn't one I'd choose. But this exposes me to other music genres and provides new learning elements. Suzanne asks us for input of which songs we'd like to learn, so the occassional "dud" song isn't really a problem.
As the skills of the class continue to improve, it might be interesting to have class members bring a song to discuss/improve with input from their peers and Suzanne - think of a writer's workshop.
For a fun guitar lesson experience, I highly recommend Suzanne.
