Leah Kruszewski teaches classical and flamenco guitar both online and in person in Seville, Spain.  Because she learned to play the guitar in her mid 20's, she understands what it feels like to be an adult beginner and gives some interesting insights into what it's like to teach an adult and why it's never to late to learn about music.
