Everyone at OK Divers is extremely friendly and patient. We had an excellent experience with Elaina (not sure if I am spelling that correctly) who was very helpful when our group of 4 asked questions about our ear, claustrophobia, and blood clot worries. She was very laid back and eased all of our nerves. She was an excellent teacher and we all felt very safe and comfortable following her lead. 2 of our friends loved the DSD dive so much they stayed a few extra days to become certified!! Overall our experience with Ok Divers was excellent. I would highly recommend diving with them!
