The Team

Alex Griffin is a Gold Course Director and technical trimix instructor. He has over 10 years of experience full time in the diving industry and over the years has worked in a number of dive centres including owning his own for 7 years. He now works full time as a Course Director and tec instructor for the London IDC and also for his tec diving school Helldivers. Alex likes wreck diving, sharks and all things retro. He is the technical ambassador for Bare drysuits and Atomic regulators and gets a lot of comic mileage out of insisting that his wife now refer to him as a ‘professional athlete’. Alex has a relaxed and friendly teaching style and loves to teach instructors. In his own words “There’re nothing I enjoy more than sitting down with a group of new instructor candidates, you’re in a room full of your peers and everyone is there for the same reason, to become an instructor because they love diving.”
