Mermaid Credentials

Hey there! I’m Mermaid Kat, and I’m thrilled to share my mer-mazing journey with you! I’ve had the pleasure of splashing into numerous events and projects across the globe.

From enchanting gatherings in Germany to spreading joy across Europe and beyond, I’m here to sprinkle some underwater magic wherever I go (or swim)! Dive into my credentials from the past few years and discover the wonderful world of my work as “Mermaid Kat.”
