I took guitar lessons from Jeff for a while back in the 90's. I've recently started taking lessons from him again. He's a fantastic musician and teacher. Couple that with being a very cool, laid back person and you have Jeff. It doesn't matter if you are a complete beginner or an advanced player who needs work on your theory, he can help you to improve.
I've been playing on and off for 35 years and had many guitar instructors. Jeff is one of only TWO that I recommend without hesitation. Give him a call, you won't regret it.
