PDI Testimonials

"I have been instructing SCUBA for 20 years, have not taken a basic certification course in at least 15, but the Rebreather Course I took with Peter was one of the best times I have had in diving! Take it you will be glad you did." 

This led me to cross over to NAUI and ultimately become a NAUI & NAUI Tec Course Director. My store is the first NAUI Tec facility in Nevada.

I have the utmost respect for Peter. His many years as an engineer are readily apparent in his approach to diving. He is thoroughly knowledgeable, and able to present the information in a clear, concise, no-nonsense manner.

My interaction and association with Peter was a large factor in my decision to cross over from being a PADI Master Scuba Diver Trainer to NAUI Instructor and ultimately become a NAUI Course Director.

If you want a thorough, thoughtful, rational approach to scuba diving I would highly recommend Peter Den Haan."

"To the NAUI Training department,

I just wanted to pass on that myself and my Director of Training, Michael Galvin, just completed the Nitrox course with Peter Den Haan, and it was one of the most informative and fun classes I have ever taken.

I'm very excited about our new partnership in training and the fact that I was trained by Peter, and will continue to be trained by him in the future. I've since crossed over to NAUI and become a NAUI Course Director.

I've continued to take my Technical training from Peter and I'm proud to say that my store became the first NAUI Tec facility in the Northwest.

You have a fantastic instructor on staff....... I felt you should hear that."
