About Me

I’m a deckhand and PADI scuba diving instructor with experience in yacht expeditions, dive operations, and guest service.

I bring practical deck skills, around 4,000 dives, and a calm, adaptable approach to life on board. My experience includes lines and fenders, anchoring support, deck upkeep, night watches, and preparing equipment for guests and dive operations.

I enjoy working with a diverse crew and doing my part to keep the team positive and operations running smoothly. I approach work with determination, resilience, respect, and a good sense of humor.

I’m looking for a deckhand position combined with dive instructor duties. Underwater photography, video, and social media management are additional skills I can bring to the crew.

Life at Sea & Beyond

I spend much of my time around the water, whether I’m diving, working on a boat, or taking photographs. I’ve dived in Indonesia, Thailand, the Philippines, Costa Rica, Galápagos, Colombia, Panama, the Caribbean, Baja California, and Brazil.

I’ll be sharing photos and videos from my travels, diving, and everyday life here. You can also see my underwater photography on Instagram, @fidiving.
