Chad Gosselin

Founder/Director/Guitar & Piano Instructor


Chad Gosselin founded the Commonwealth Music School in 2010 with the goal of starting a quality, contemporary music program near his hometown.  Growing up on the south shore of Massachusetts, he wanted to create the performance opportunities and culture he found lacking in his own experience.  With a focus on contemporary music, student-based learning, and community, the Commonwealth Music School has become the premier place to learn music on the south shore.

Chad Gosselin began studying guitar at the age of twelve years old, and holds a B.A. in Music Performance with an Emphasis in Education from the University of Massachusetts where he studied jazz guitar pedagogy under Jon Wheatley.  He has been playing professionally and teaching private lessons, ensembles, and songwriting since 2002 teaching hundreds of students over the years.

Chad is the singer and guitarist of the nationally touring indie rock-band, The Big Lonesome.   You can hear more of their music at:

Stefan Anderson

Guitar & Piano Instructor


Stefan Anderson is a pianist, guitarist and composer with experience writing and performing in classical, folk and rock styles. He received his Bachelor of Arts in music from Bennington College where he studied composition with Allen Shawn and piano with Yoshiko Sato, whose rigorous yet student-led teaching style made him a passionate pianist and also eager to introduce new students to the piano with a similar method. At Bennington, Stefan performed piano music from all different musical periods, including his own compositions, and received the John Hendrick Memorial Commission Award.

Recently, he graduated from Tufts University with a Masters of Arts in music composition after studying with local pianist/composer John McDonald.
