Ethan Noll TEACHER

As a young kid Ethan remembers discovering rock music on the radio. It was at that moment when he first heard the intensity of bands like Nirvana and Metallica and knew that it was something that he wanted to do one day. The more he listened the more he fell in love with the music and the idea of freedom that music created. 

Ethan bought his first guitar when he was 15 and never looked back. He started building guitars back in high school and later on became an instrument repair technician to further explore the trade. Ethan is continually trying to learn and discover new instruments and musical styles to expand his musical horizons and vocabulary. The main instruments he plays include guitar, bass, drums, vocals, and cello.

Ethan has helped out with rock/music camps and programs out of the local area in the past, as well as given private instruction.  As soon as he heard about RiverCity Rock Star Academy here in Salem, he knew he had to be a part of it. Now he’s using the opportunity to help give back some of the experiences he’s gained and share some of the lessons that music (and amazing people and musicians throughout his life) have taught him. Rock on!

mark & Karen green - co-founders

Mark’s love and appreciation of music goes back as far as he can remember.  From playing LPs over and over, to spending hours in records stores in Hollywood, to attending numerous concerts at small and large venues in Southern California and the Portland and Seattle area.  Although he took up guitar when he was younger, he gave it up and didn’t pick it up again for another 30-plus years.  Mark now loves to play guitar every day and has even performed with others in front of a live audience.  He does admit he continues to learn and grow every day as an adult musician.  When Mark’s not playing guitar, he’s a consultant, public speaker, author, educator, and researcher ( and (Pacific Family Business Institute).

Karen also grew up surrounded by music.  She remembers the sounds of various genres of music playing while at home and in the family car, but she especially remembers the classic rock tunes of Fleetwood Mac, The Who, Wings, The Rolling Stones, and The Eagles.  Although Karen appreciates all music and musical talent, her own musical experience is limited to her short stint as a guitarist in the family band.  However, Karen’s non-musical professional experience includes marketing and promotions, public relations, writing and editing, and program coordination.

Both Mark and Karen know there is a tremendous amount of musical talent in the Salem and surrounding areas, but realized there were not many places for musicians in the area to come together, learn together and play together.  They especially recognized this when looking for a place for their own teenage daughter and her friends to play together on a regular basis (besides the cramped basement or garage).  RiverCity Rock Star Academy was created just for that reason!!
