5.00We completed our Open Water and Advanced Diver certifications here; we had never dived before. However, we felt well taken care of right away. Joaco showed and explained everything excellently, and we all felt safe the entire time. The groups here are very small, and one instructor always has about 3 students (which is often not the case at other diving schools). I would definitely recommend it to everyone. The other diving instructors and divemasters are also very nice, and you can approach them at any time. Even when you are not diving, there is always someone available throughout the day to whom you can go.

5.00I didn’t expect this experience to be this amazing… Diving is truly one of the most incredible things you can do, especially in Koh Tao. Choosing DPM was definitely the right decision. They are extremely professional and clearly know exactly what they’re doing. My instructor, Joaco, was very professional, attentive, and always focused on making sure you feel safe while enjoying every moment of the dive. He teaches you everything you need in a clear and reassuring way. Also, Hollie was fantastic! She helped us with everything and made the whole experience even smoother. 10 out of 10, guys!
