David Deppeler, DSc, PT, is a breath scientist and coach, movement specialist, and founder of Breathe Your Truth. With a Doctor of Science in physical therapy and decades of experience in clinical practice, performance coaching, and ancient Qi Gong traditions, David helps people build smarter, more resilient breathing habits—from the inside out.

He’s worked with Olympic athletes, Nike and Under Armour pros, and everyday humans dealing with stress, pain, and chronic tension. His approach blends science and soul, guiding readers beyond the hype to what actually works.

Breathwork Exposed is David’s call to cut through the noise and rethink the way we breathe—for better energy, focus, and long-term health.

When he’s not writing or teaching, David spends time with his partner Marcel, leads spin classes, shares Qi Gong, paddles Wisconsin lakes, and walks his dog at sunrise.
