He attended Stevenson School and was the co-founder of the Monterey Bay Area punk rock band Amphoteric. He would later leave and the group would switch directions and gain a progressive metal following (especially amongst Internet listeners). Although the line-up has changed entirely, the group still resides in central California and continues to release albums independently.
