Kirk Krack is a professional freediving trainer and coach who has worked with eight current world record holders. Kirk has an extensive recreational and technical scuba diving background as an instructor trainer in trimix and mixed gas diving as well as ice-diving and other related fields. With this experience Kirk has been involved in numerous freediving events as diving supervisor, safety diver and videographer for freediving pioneers like Pipin and Audrey Fererras.

As an instructor for Performance Freediving International, Shell ventures across North America teaching the intricacies of deep freediving. “I want to help the freedive and spearfishing community become a safer and more conscious community. We are each capable of incredible depths and seemingly absurd breath holds, and I find deep satisfaction in coaching divers to their own freedive goals.”

Ren was born and raised in Wilmington, NC, a quant, seaside community rich in history and natural resources. “Freedive instruction has to be the most rewarding thing that I have ever done. When folks come into these courses and completely blow the doors off of their expectations, it is just amazing to see their excitement and it makes me feel like a million bucks because I helped get them there.”
