About Instructor Development Philippines

As the only two PADI 5* CDC facilities in the country that collaborate and offer you two multiple award winning in-house PADI Course Directors to guide your training we guarantee you will not only have the best IDC experience possible but also a lot of fun in the process.

IDP is more than just a training facility. We care about each candidate and apart from offering exceptional training we also offer support to each individual long after they have successfully completed their Instructor Exam.

We are still in contact with many of our previous IDC graduates, most of whom return to Liquid and Atmosphere for regular diving holidays and tell us stories of their amazing lifestyles working their dream jobs in exotic locations, a few have even gone on to open their own dive centers; and we are there to help with any questions they may have.

Our IDP graduates are one of our strongest assets having dive jobs all over the world, creating a network that we can tap into to help our newest batch of graduates in the search for their dream job.

Our IDP graduates are now working in:

They all help out during both class and water presentations and create a wonderful support team for all our candidates. We also offer support for our IDC candidates in a variety of languages including Dutch, French, German, Russian, Spanish and Swedish.

Tim Latimer

PADI Silver Course Director

Tim first learned to dive when he was 16 on a school trip to the Bahamas. Since then he has tried his hand at carpentry, social work, managing coffee shops, bank manager and generally spending time travelling and trying to figure it all out. Finally he decided to stick with the thing he fell in love with at 16. In 2002 he settled in Utila, Honduras and became a PADI Open Water Scuba Instructor.

Making good use of his new cool job to pick up girls, he promptly met Zoe who he married a year later!! He also reads comic books so most of his cool cred went out the window with that one. Tim is now the in-house multi-award winning Course Director for Liquid, now a PADI 5* CDC dive resort, working together with Atmosphere Resorts to provide IDC’s to people looking to make diving their career, through Instructor Development Philippines.

Diving her way round South East Asia for two years, Gabrielle settled in the Philippines and became a PADI Diving Instructor and Manager of a Dive Centre in Boracay.

She met her husband Matthew when he signed up for her Open Water course in 2001, they were married in 2006 and have two children. Gabrielle truly believes this is the best job in the world and became a PADI Course Director in 2003, her career didn't stop there and together with her husband Matthew, they decided to start their own dive centre and resort. Atmosphere Resorts, now a PADI 5 Star Career Development Centre was opened in 2008. Gabrielle's true passion is teaching diving, with no greater job satisfaction, but living on the Dauin coastline, it has to be said that critters are her favorite thing to see underwater.
