Our Butterflyfish loving Brit Alex has been living here on Koh Tao for over nine months, and happily for us, is still loving every minute!

Alex learnt to dive when he was backpacking in Australia. During his internship, Alex did some awesome things – and he says that one of his highlights was the opportunity to guide certified divers around the Great Barrier Reef, and world-renowned shipwreck SS Yongala.

Europe called, however, Alex didn’t abandon diving as he went on to complete my ITC in Ios, Greece before moving here to Koh Tao in December.



Anna grew up by the seaside after her parents left her there one summer. Unfazed, this Swedish beauty spent her early years, living on a boat and sailing the chilly Scandinavian waters. She grew up with salt in her hair and knew the water would look after her in years to come. Anna’s first experience with scuba diving came at the tender age of 12 right here on Koh Tao . Needless to say, she liked it!

Having finished school, Anna spent years living in the remote outback of both Sweden and Norway, hunting bears and moose and living off the land much like a scandinavian Mick Dundee. However Koh Tao & its’s crystal waters were never far from her mind!! In 2011 Anna packed her bags & flew back to Thailand….after hearing it was too far to swim.

SSI Speciality Instructor Anna loves nothing more than exciting customers with tales of the sea and how she rescued a wolf from almost certain death at the hands of a sabre tooth cat. She is a natural in the water and her passion for marine life is evident. Anna truly believes in the words of Confucius “choose a job you love, and you will never have to work a day in your life”.


Rachel V

Our pint-sized Scuba Ninja Rachel joined us as a Dive Master and quickly smashed her way to becoming a Dive Instructor. Quietly spoken, Rachel doesn’t suffer fools and despite her small stature — she’s not to be crossed!

That being said, she is one of the most intelligent, patient and kind people you’ll ever meet and learning to dive with her is a joy. She is passionate, friendly and lives the mantra ‘Fish are friends, not food’ (she’s a passionate Vegetarian!).

Rachel B

Rachel is one of a significantly large proportion of Rachel’s at Roctopus Dive and is therefore typically known as just Belton. For obvious reasons.

Rachel learned to dive while at uni and completed her open water dives in a quarry. Despite only seeing one fish in 4 dives, she was hooked. But soon a conventional career in retail came calling.
Luckily for us, she came to Koh Tao to meet a friend, the legend that is Roctopus Dive’s Head Dive Master Gary Williams, who persuaded her to complete her Dive Master training. She worked hard on her initially awful navigation skills and soon became one of our busiest Dive Masters.

Not content with that, she pushed on to train as a Dive Instructor with us. Since that time, she has been enthralling students with her witty banter, multi-coloured hair (don’t ask about the time she decided to dye it blonde while in Thailand), and questionable dance moves. Just don’t challenge her to dance off……

Pete is the Manager and an Instructor Trainer at Roctopus Pro. He learned to dive in the cold waters of his home town of Boston, Massachusetts. Even though he saw nothing but a single lobster on his open water course, he fell in love with the sport of diving and decided to make a career of it.

Pete has a graduate degree in statistics from Harvard University and previously used his talents to create custom financial software that billionaires used to manage their money. In 2012 he decided he wanted a change of lifestyle and took up becoming a dive professional. He now pours that same drive and ambition into his passion for diving.

He was previously a manager and head instructor of another dive school on Koh Tao before taking over as the manager and IT of Roctopus Pro in March of 2015. He has certified over 500 divers and instructors.

He also developed his own software to manage dive shops, which is currently being used around the island of Koh Tao. When not diving look for him on stage playing bass with the Koh Tao Pub Crawl cover band.



Emma is one of the most interesting people you’ll ever meet. Known to all her friends as a persistent workaholic, Emma is in a beautiful life partnership with the Ocean. She has found her dream job, and she excels.

An experienced Dive Instructor and active marine conservationist, she often boasts that the most fun she has ever had was at 27m, scraping the paint off our beautiful wreck the HTMS Sattakut.

This Scottish lass has travelled the world diving. Let her inspire your next adventure with stories of the Great Barrier Reef, going primitive in the Torres Straits, diving with giant Manta Rays, exploring the wrecks of Malta, and her close encounters in shark infested waters in the Bahamas.

When not underwater Emma will be seen wearing her cowboy hat, being artsy and running around organising everything she can get her hands on.
