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!

5.00I had an amazing experience getting my Open Water certification here! From start to finish, everything was perfect—the facilities, the dive school, and the hostel made it an easy and enjoyable experience. The entire staff was professional, friendly, and always ready to help, I had to do some changes and they have been flexible and helpful ❤️ But the real star of my experience was my instructor, Natasha ☀️ She was incredibly supportive, patient, and knowledgeable, making me feel safe and confident underwater at all times. She explained everything clearly, always checked in on how I was feeling, and made sure I truly understood every step of the way. Her passion for diving is contagious, and I couldn’t have asked for a better instructor! If you’re thinking about diving, I 100% recommend this school, and if you can, ask for Natasha—she’s the best! 🤿

5.00I booked it as a last minute option for my open water course. The communication was great from the start, George replied super quick to my queries. Tomas was helping me to register a day before I started the course, he was super nice and helpful. My instructor was Esna, she was very helpful from the beginning to the end. If I had any questions she took her time and patience to guide me. I can say that I feel way more confident now underwater and looking forward to continuing my diving journey. Dpm is a great place to do your diving courses. I cannot recommend enough. Fantastic team! Everyone is welcoming! Thank you for everyone!
This is the best diving place on Koh Tao!!

5.00Open water 30 and the advanced course! What can I say, DPM felt like a family the second I arrived, George and Anna were so welcoming and friendly and helped me out with everything including accommodation and sorting out my courses and answering any questions I had. My open water 30 course with Colo was amazing he is a great teacher and honestly he has made me want to pursue a career in diving. He was patient and explained everything fully and ensured everyone was okay and safe at 30 m down. My advanced course was done by Sergi and he was great he helped me learn my buoyancy and how to navigate under water, he took me on 2 wreck dives and a night dive and he made sure to show everyone all of the different marine life, I was lucky enough to see an eel, octopus, hermit crab, some huge puffer fish, and a grouper that probably could have fit me inside it x2. Not only the courses were great, the social side of DPM is what makes it stand out. I had met people on the boat that were doing dive masters and ended up spending most of my time with them to even going to a meal with all of the DPM staff. 10/10 would recommend and I will be going back in a few months to complete my dive masters and maybe the instructor course with them!
