Poh Chang has been teaching for more than 14 years and has trained recreational divers, technical divers, instructors and instructor trainers.  He is an instructor with NAUI, IANTD, DAN and now, UTD.  His key focus is to provide safe and quality training, actively promoting UTD/Hogarthian/NTEC philosophies and encourages divers to be a "thinking diver".

His diving has mainly been in exploring the deep wrecks in South China Sea, spectacular wall diving in Celebes Seas and atolls of the India Ocean around Asia Pacific region. In his leisure time, Poh Chang has developed a new passion, that is to cruise through the wrecks with his underwater scooter and documenting the wonders of underwater world with his video camera.

Dawn Tan

Dawn has always loved an active lifestyle and trying out of new sports. From jogging, kickboxing to rollerblading, none has managed to make her fall in love with though she still occasionally does it. In year 2005, Dawn decided to go underwater and took up the Open Water Diver course. Since the day she had been certified, she was mesmerized and her thoughts has been all images of the underwater beauty. She fell deeply in love with the other part of the world.

Diving Career and Experience
Dawn Tan only started diving in 2005.  Her love for the underwater grew into passion where she urges herself to pursue more knowledge. She completed the Advanced Scuba Diver, Stress & Rescue, Master Scuba Diver, Deep Diver, Enriched Air Nitrox and Advanced Air Nitrox over a span of 2 years.
Still eager to learn, the next step she took was to move on to a more responsible role - being a Divemaster. She feels that it is a totally different aspect of learning diving. Dawn loves teaching and wants to share what she knows with people who are curious with the underwater. In 2007 she was certified as an instructor. She is very motivated when she sees her divers complete the course and enjoyed the diving experience and wants to move on to the next level.
