Why Does Experience Matter?

Because…. It just does

When you’re learning percussion, especially marching percussion, your foundation determines everything—your technique, your confidence, your opportunities, and how quickly you improve.

That’s why who you learn from matters just as much as what you learn.

With years of performing, teaching, and coordinating at the highest levels of the marching arts, I bring real-world experience that directly benefits every student.
