What is oxy doc?

Australia, Nettlebed Cave, Brigitte

Australia, Weebubbie Cave, Oliver

Florida, Eagles Nest


oxy doc is a concept that was founded by Brigitte Bergmann and Oliver Mueller.

The idea is simple: as you plan more exciting and distant adventures with your diving, the more important becomes local knowledge. We are happy to offer advice to divers who wish to travel with their diving, and share the benefit of our experience. We would like to network with other divers and are happy to answer your questions!

*** a big THANK YOU to our australian friends *** and un saludo a Madrid!
