The best divecenter in Greece! John is a verry good instructor and nice dives

John did a fantastic job taking me through my instructor development course and PADI exam. Very thorough training with attention to detail, I feel well equipped to start off as a new instructor

Seals Diving Center was an amazing experience. We came to Athens and spent two days at the beginning of our trip getting our PADI scuba certification so that we could dive later during our vacation. John, the owner, was kind, generous with his time, and a great instructor. I was nervous to start, and he walked us through everything we needed to know to safely start our scuba journey. I would highly recommend Seals Diving Center if you are interested in scuba. You will not regret it.

John, the owner and instructor is one of the best divers I have had the pleasure of diving. He is very knowledgeable and very patient when teaching. He takes security and the PADI standards very serious and makes sure you as a student/diver are understanding the terms and the whys on how to do things. I did rescue diver and continued with divemaster with Seals Diving because John and his team are very professional and you are definitely learning Scuba diving the right way.

We had a wonderful experience with Seals Diving! John, owner/instructor, was so patient, understanding, and knowledgeable. I left the experience feeling like a confident diver. You are in good hands with Seals Diving - it’s an experience you won’t forget!

Went with them for a double dive and dont really have anything to complain about. They provided transport to the site and even brought along food and water. They also dropped me off along the way near the train station, so that was super nice. Only thing I'd say is that where I found the dive shop, was not where it is shown in Google Maps. I found the address because it was in the email they sent. So make sure you know where to go

well overall nice experience BUT I’ve got a voucher as I gift from a friend. She was informed it will be a lesson about diving, transport from Pireaus to the point of diving. Diving first from the shore and after that we will go to the boat to dive from there. The reality: no transport was provided I had to take 1.5h bus, no lesson was provided- they just mailed me to download it and read it. The instructor didn’t speak English (my Greek is very limited) There was no diving first from the shore they took us straight to the boat which for me as it was first time trying scuba diving quite difficult. After that instructor told me it would be better to try first from the shore…I mean really???😂 They all were very nice but still it was a bit of disappointment and waste of money for my friend as promised services were not provided.

Great experience, would definitely recommend. Ioannis was a great teacher; very patient and did well to tailor his teaching style to make my partner feel comfortable underwater. Big thanks to him for starting my diving journey on a high

I did my OW course with Seals and it was an excellent experience, the staff is very professional and super reliable. Special thanks to Kostas who was very patient with me. John and his team will give you the best training, if you are thinking of getting your PADI certification in Athens don't hesitate to come here. We also did our nitro course at the diving center. We dived at Vougliameni which is a very nice spot.

Fantastic experience! I had the pleasure to do my Advanced Open Water PADI certifications with Ioannis (a.k.a John) last Sep/Oct. From the first email I sent inquiring about the prices, conditions, etc. John has been exceptional in every step. Very friendly, considerate, flexible, and, most importantly, safety-conscious. As a result, I ended up doing Nitrox, First Responder, and Rescue Diver certifications as well! In addition, the staff at Seals is equally fantastic. In particular Vasilis (instructor) and Lydia (assistant instructor) have my respect and gratitude for their professional yet friendly demeanor, which helped me feel part of a family. I also took a friend to do Try Scuba, which she loved. Would most certainly dive again with Seals on my next visit to Greece. In fact, I'm looking forward to it!

Excellent instructor, with deep knowledge. John and his team made me feel really comfortable and relaxed, despite being anxious in the beginning of the dive. I strongly recommend John and Seals Diving Center. Thank you for everything!!

Everything perfect!! I recommend the school without reservation
