Very personable and flexible! After worrying about whether we would even be able to dive on Koh Tao before taking the 4:30am ferry, we luckily found this diving club. The team was very flexible and accommodating and rescheduled the dive trip for us the next day so that we could make it to the ferry in time after the dive. The team with Charlie, Leah, Sita, Lukas, Angie and Max are as professional and friendly as they are international. Thank you for making it happen! 🤿😊 Cheers!

Perfect diving school! We went diving as a group of four in the japanese gardens. Our instructors Leah, Sita and Charlie and also the rest of the team as Lukas, Angie and Max were super nice. They gave us a good overview about all the things we should know when diving and one did feel safe around them. I can only recommend doing it as the price is also super fair.

Me and my friends went diving with Max, Sita, Charlie, Lukas, Angie, Leah. Sita was supervising two of us while learning the basics, enjoying the corals and observing the wildlife. Would recommend everybody to experience it with this professional team Also heard Felix is a great guy for supervising dives.
