My passion for diving started snorkelling around the Great Barrier Reef over 20 years ago. I overheard some divers talking about their dive on the boat. I found a local dive shop offering try dives, and that was it. I have dived around the UK (including Scapa Flow), Greece, Canary Islands, Red Sea, Maldives (where I saw my first Whale Shark and Mantas). I love helping out on courses and get a real buzz when students they crack a skill they may have found a challenge.
Steven Maher
PADI IDC Staff Instructor, EFR Instructor
After a difficult diving experience in 2018, I chose to start fresh on the PADI path—and I haven’t stopped since. I progressed quickly through the recreational levels, eventually answering the call to go pro. In October 2020 I became a Divemaster, followed by earning my Open Water Instructor rating in December 2021. By June 2024, I had advanced to IDC Staff Instructor.
I’m qualified to dive in both twinset and sidemount configurations, and to further sharpen my skills I completed a full-face mask course—definitely not for the faint-hearted, but it opened up an entirely new side of diving.My adventures underwater have taken me to the UK, Turkey, Cyprus, and Egypt, with many more destinations planned for the near future.
When I’m not in the water, you’ll usually find me hunting for new and shiny dive gear. And if all else fails, I can be easily bribed with cheesy chips and Haribo.

I tried diving with Aquatech for the first time as a broke uni student. From my first breaths underwater I knew I’d found my passion so I saved up all my money qualifying as a diver in 2018 and an instructor in 2024. My diving career has given me opportunities to work in Cornwall and Spain but Ive always felt most valued and comfortable at Aquatech! Ive dived in some beautiful destinations with Egypt being a personal favourite! I’m always looking to move forward with my diving education and share this with students and fellow divers
Outside of diving I run a dog grooming business and have too many hobbies to keep up with, but the current fixation is crochet!

Olivia Boland
PADI Divemaster Candidate
I did my first dives with Aquatech on my open water course in 2025 and instantly fell in love with diving. I knew from that moment this is what I wanted to do for the rest of my life. Since then I’ve done multiple courses with Aquatech leading up to my divemaster this year. My love for diving led me to Lanzarote where I get to see angel sharks, octopus, seahorses and different types of rays!
