Gio discovered his love for caves in Brazil before deciding that spreadsheets and boardrooms were far less interesting than dark places with guidelines. He traded an MBA and a career in management consulting for technical diving, a path that eventually brought him to Third Dimension Diving in Tulum, Mexico.

He is an IANTD Instructor Trainer, a Fathom IT, and part of the 3D Instructor Development group, teaching the majority of the CCR courses that run through 3D. He prefers his dives silent and bubble-free, ideally inside caves or wrecks.

Gio lives in the jungle, balancing teaching, diving, and training with coffee and lifting weights. He teaches in English, Portuguese, and Spanish.
