Calm instruction built around confidence, awareness and preparation.

I teach calmly and practically. My aim is not simply to help someone complete a course, but to develop confident, observant divers who think clearly, control their buoyancy and make sound decisions underwater.

The same safety-led approach runs through my scuba and freediving instruction, first-aid training, technical-diving experience and emergency-response work.
