Karyn Hanson
I've been involved with music in many ways over the last 45 years. I began playing guitar in grade school and have been honored to be a student of classical guitarist, Michael Davis. I have experience with the music business as a concert producer at Portland State University. I am currently finishing my degree in Music and Sonic Arts at Portland Community College where I perform solo and as a member of ensembles. I excel in music theory and composition and have many years of teaching experience. I've been a music coach at American Guitar Academy since August of 2019 and am currently coaching guitar, piano, drums, voice and ukulele.
Isaak Boorstein
I have always enjoyed singing and performing. When I was fifteen, I took my first music course, a guitar, songwriting, and music history class. Ever since, creating music has been a main driving force in my life. Growing up, our house was full of all types of instruments. Over the years, I would teach my friends instruments so that I would have people to play music with and, in doing so, I discovered that teaching is something I love to do and have a talent for. At the University of Oregon, I studied Music Production and Performance, starred in the UO's production of Once: The Musical, and acted as the vocalist and guitarist for the School of Music's Pop Ensemble. I sing, play guitar, and piano in two local Portland bands, and produce music for a few PNW artists. I love talking about music and music history. At AGA, I coach guitar, piano, drums, ukulele, and vocals.
Bill Hernandez
I have always loved music. It all started Sunday, Feb. 9, 1964... the night the Beatles first appeared on the Ed Sullivan show. Not really sure how my parents felt about their eight year old son wearing a Beatles wig shouting "She Loves You Yeah Yeah Yeah!!!" but it didn't matter because I was hooked. From my very first concert (Sonny and Cher) to the one I saw most recently (Elton John) and the hundreds more over 50 years, I love that music is the chronicle of our lives and I love the ability it has to bring back memories. Now at 66 years young, it's time to start creating new memories and passing on what I've learned to others. No matter what it is in life you’re passionate about, pursue it like there’s no tomorrow. I am currently coaching guitar and ukulele.

I've been a piano instructor since 2018. I earned a B.S. in Piano Performance in 2023 and have performed in piano and choir ensembles at PCC and PSU. I enjoy teaching students of all ages and like making lessons fun with humor. Outside of teaching, I like reading, arranging songs on the piano and spending time with my pet chickens. I'm currently Coaching piano and beginner ukulele at AGA.
Ty Brintnall
I'm a dedicated guitarist and pianist with over ten years of experience. Starting at the age of eight I've been relentlessly perfecting my skills and knowledge and have since gained more and more experience passing on my passion and dedication to learning music to others. What excites me the most about being involved with music is helping to bring more musicians into the world, performing music for others and helping people live better lives through the gift of learning music. I am currently coaching guitar, piano, drums, and music theory at AGA.
