Thom Robbins
SDI Instructor Trainer
Thom started diving in 1987 and continues to learn even today. Diving was a natural extension to his love of the water and the creatures that you find. While he enjoys warm water, the cold water of the Pacific Northwest holds his passion. As an avid photographer, the clear cold waters we enjoy here are the home of some of the most beautiful creatures. One of Thom’s passions is helping people to learn how to safely pursue their own love of the water. In 2022, Thom earned the top rating from SDI, and is now an Instructor Trainer.
Thom also has been busily writing marine ID books, and lately underwater fiction novels. You can see his latest here.
If not teaching or writing, , you can usually find him looking for that perfect shot at one of the many dive sites in the area.
