About Crescendo Missions

A name rooted in worship. A mission shaped by service.

Crescendo began with Charles Cheng, MD, and Karen Cheng, DMin, who co-founded Crescendo Music to create original Chinese worship music and support people in need. Their albums, Dawn to Dusk and Before Your Throne, were an early expression of that shared calling.

Our story

The work took a new form.

As Charles became involved in surgical mission work, the same desire to serve found a new expression. In 2026, Crescendo Music became Crescendo Missions—a name that speaks more clearly to the work today while honoring where it began.

The heart behind the name

“He must increase, I must decrease” (John 3:30)

These words continue to shape our posture. We seek to offer our skills with humility, compassion, and respect for the people and communities we serve.

Our leadership
