What happens when you reclaim the identity you've been running from your entire life? Siegfried Jay Tiegs aka "Sig" takes us on a raw, unfiltered journey from childhood trauma to profound self-discovery in this deeply personal conversation.
Born to a German father carrying the weight of post-WWII trauma and a Dutch mother struggling with mental illness, Siegfried's early years were marked by abuse, poverty, and relentless bullying. Hating his unusual name and battling a severe stutter, he rejected "Siegfried" for "JJ" – a small act of self-preservation that would take decades to understand and ultimately reverse.
Through intensive personal development work and deep shadow exploration, Siegfried made a stunning discovery – his birth name, which he had rejected in shame, means "peaceful warrior" in German. The very identity he had been running from was precisely what he had been seeking to become. This epiphany led to a powerful ceremony at Machu Picchu where he reclaimed not just his name, but his authentic self.
