CHRIS RAMUSIEWICZ has been giving private instruction for guitar and bass ever since graduating from the University of Massachusetts-Boston in 2012 with a BA in Music, in both group and one-on-one settings, and with students of all ages and backgrounds. Since starting out in teaching, he has grown to love the feeling of seeing a student grasp a new concept, especially if it’s been a previously frustrating issue for that person. Chris has also been an avid composer and performer, dabbling in styles from metal, pop, solo finger-style guitar, and even synthesizer heavy electronic music.
