Diving Matrix was started by Paul toomer in 2007 based out of London, UK providing technical training with PADI DSAT, IANTD, TDI.
It ran regular trips to: Malta, Mexico, South Africa, and Sardinia.

In 2010 Matrix added RAID to their line up of technical agencies, and was one of the first to start teaching Poseidon MKIV courses. Tec Lab Malta was opened as well.  In 2014 Paul joins RAID as a co-owner, and Global Training Director, naturally Matrix now focusses on RAID & IANTD. Jason Selway joins the team as one of the youngest Poseidon MKIV instructors world wide. Between 2014 and 2016, Paul's focus is mainly on RAID, while Jason focusses more on his career. Ian France continues to teach under the Matrix banner, and eventually in 2016 announces a partnership with Dave Gration and eventually just focusses on his own thing.

After a perioud of relative inactivity, in 2017 Olivier van Overbeek (Oli) joins the team by invite from Paul Toomer and slowly takes a leading role with Diving Matrix. As Oli moves through the ranks at DiveRAID he starts working with the International Training Department as a consultant, and a Technical Instructor Trainer, in 2018 he becomes a CCR IT as well as purchases DiveLife the scuba retail shop, in 2019 he accepts director of training for UK and Malta.

Olivier van Overbeek


Rec & Tec IT, CCR Instructor Trainer & Training Director for Dive RAID UK & Malta.

Oli started diving in 1998, on holiday in the south of France, he instantly fell in love with the underwater world, and when he came home to his native Holland, instantly signed up with famed Dutch wreck explorer Ben Stiefelhagen. A few months later he moved to the south of England, and continued diving and learning there.

In 2000 he was enjoying the popularity of diving the south coast was experiencing at the time, and joined as many dives as time and money would allow. After spending several years diving just for himself, Oli decided to become an instructor.

After attending a lecture with Steve Lewis he decided to find a more technically oriented agency and wanted to help make changes to the industry. It wasn't long until he met Paul who at that point had just joined RAID, and decided to jump on board.

After joining RAID he started working with, and learning of Paul directly, and in 2015 joined the first RAID ITD program.

Oli enjoys working with instructors or teaching Technical programs most, but is always happy to work with any diver level.
