Your Instructor
I am a music geek fascinated with learning new things, and improving my guitar skills. But I'm also very passionate about helping others do the same!
After studying in the Greek National Conservatory, and Berklee College of Music, I began performing and teaching privately in 2001.
Since then, I have been developing new methods for effective musical training. My mission with String Systems is to share them with the world :-)
