Jimmy Chen is the founder of the Vocal Activation Method (VAM), a structured approach to voice development designed to help clients build greater control, consistency, and authentic vocal expression. VAMethod is built on the functional voice principles of Cornelius Reid, one of the most influential vocal theorists of the twentieth century.

Berklee-trained, Jimmy adapted this lineage for trans voice development, drawing on a decade of experience working with elite performers and executives. His approach combines technical voice training with a deeper understanding of breath, function, perception, and expression, informed by hundreds of studies on gender expression.
