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 have enjoyed listening to and making music since I was very young, and what I love best about music is sharing it with others. I've taught in classrooms and studios, directed church choirs, played in orchestras, bell choirs, bluegrass groups and marching bands. I'm currently playing in the Hillsboro Symphony Orchestra, Westside Community and Youth Orchestra, and some ensembles in my faith community. I enjoy helping new musicians find joy in expressing themselves through instruments and voice, and learning from them in return! I am currently coaching guitar, piano, drums, voice, ukulele and music theory at AGA.

Brandon Wareing


Hailing from Northern California, I am a die-hard music fanatic. I picked up my first instrument – the bass guitar – in high school, and after graduating went immediately to College of the Siskiyous to study music. While there, I found a love for teaching, as I helped tutor for the Music Theory classes, transposed and arranged parts for the orchestra, all while playing in local groups and ensembles.

Now with more than five years of teaching experience under my belt, and a grasp of guitar, bass, ukulele, piano, and drums, I'm happy to share everything I can here at AGA Music Lessons. I hope you'll give music a chance, and come learn about the infinite journey of spirit and sound that music has to offer!
