MEET THE TEAM
Instructors from around the globe who can deliver the Human Diver programmes.
If you are considering an investment in training around diving as a sport, pastime or profession – you should be considering human factors as part of that investment.
The Human Diver has a team of qualified professional instructors, all experienced divers, who can deliver our courses. They have undertaken hours of human factors training, in person, online and through group work to become accredited. More are due to train as instructors this year and beyond.
Our mission is to be able to offer this kind of holistic training globally to anyone who wants to further their knowledge and minimise risks around diving – whatever their level of technical diving ability or experience.
Heading the team is Gareth Lock.

Background:
Beatrice is an Italian vocational diver with a Master’s Degree in Marine Biology and Oceanography. Her main interests in these fields are related to extreme environments like the poles, deep-sea habitats or caves.
Diving Experience:
Beatrice started diving in 2001 and soon realised that, from that moment, it would have been an important part of her life. She now works around the world as a CCR & OC instructor participating in biological/archaeological underwater projects and underwater maintenance works.
Human Factors Commitment:
As soon as Beatrice discovered a little more about Human Factors and their role in diving, her view changed completely. She can't "unsee" now and this had a strong influence on both her diving and teaching methods. Integrating these concepts in her diving classes became natural and she hopes that more and more divers will soon understand the great value of these topics.
