Will North, Co-Owner + PADI Dive Instructor 498156  (Canada 🇨🇦)

Will’s passion for diving began in 1998, when he first learned to dive on the Great Barrier Reef during a backpacking trip. During his open water dives, he was hooked on the feeling of near-weightlessness. He returned home to Canada and taught public school for 8 years, but he never forgot his love for the ocean. In 2008, he took a leap of faith. He left his job, sold his house, and moved to Thailand to become a dive instructor. This was a very good idea, and he hasn’t looked back since. Will spends most of his time welcoming guests, scheduling, organizing and supporting the incredible dive team at Ocean Sound Dive & Yoga. He also enjoys playing padel, hockey + golf, travel and aviation.

She decided to change her travel plans and her life plans. She gave up her plane ticket to go home, became a dive instructor, and has been living the dream ever since.

Jessica Willis, PADI Dive Instructor 579794 (UK🇬🇧)
