About Us


Extreme Atmospheres, a diver owned and operated business was newly founded in 2022. The owners, both certified divers in many disciplines of diving including the Technical and Professional levels of diving, prefer to spend all of their time under the water, whether it be practicing, training, exploring, or photographing the underwater world. Extreme Atmospheres may be a new business but is definitely not new to the underwater world of diving. We look forward to sharing our experience, knowledge, and love for the sport of diving with all that dream to venture beneath the surface to the amazing world that lies beneath. Come explore the sacred underwater world with us. 

                                  Safe Diving,


                                  John and Holly German
