Andrew Withiam


Westchester, NY

Andrew Withiam spent his childhood listening to a mixture of pop, classical, and Broadway music. Thanks to his piano teacher mother, he began learning piano at the age of eight. Years later, Andrew was exposed to his first taste of guitar-driven music, specifically classic rock, hard rock, metal, and grunge. This inspired him to immediately pick up the guitar.

After spending a chunk of his formative years studying under jazz guitarist John Pondel, Andrew majored in music and economics at Hamilton College in upstate New York, graduating in May 2020. He spent much of his time studying music theory, jazz, songwriting, sight-reading, studio production, and audio tech, all with the guitar as his instrument of choice. He culminated his undergraduate studies with the release of a self-produced album and senior jazz performance of Django Reinhardt pieces.

Manny De La Luz

Manny De La Luz

Guitar, Strings, Winds

Chicago, IL

A gifted string teacher, Manuel De La Luz has been teaching music in both private and classroom settings for six years. From the start, Manuel knew his passion and talent would be found in teaching. This led him to Chicago's VanderCook College of Music, where he studied violin with a dual emphasis on teaching and performance. He was a student of renowned violist Dr. Michael Hall, through which he learned the string coordination technique codified by Karen Tuttle. Beyond violin, Manuel also utilized his time at VanderCook to study viola, cello, and bass performance and education. It was also during this time that he fell in love with the guitar. Using his knowledge of violin, Manuel quickly mastered standard guitar repertoire in just three years.

Through his self-taught experience, Manuel has developed an innovative approach to guitar. By transferring methods he learned on bowed string instruments to the guitar, Manuel’s teaching approach has gained outstanding results among his students. In using Karen Tuttle’s coordination technique in guitar lessons, students are able to reach levels of performance beyond the technical aspect of playing a musical instrument. Manuel’s clear communication and attention to detail create a fun learning environment. He can’t wait to share his knowledge with new students!
