I just wanted to let you all know out there that I just got back from Cozumel and dived with this company. They were excellent and worked with experienced and new, nervous divers alike (I was the latter!).
I would recommend them very highly. It is a very professional company and Christi's staff are of the very highest standard.
I had Blanca as my divemaster, and Arturo with the other, better divers, and we could not have had a better time!
I was so impressed!!! Believe me, as a nervous diver, feeling comfortable is of the utmost importance, and they made me feel like I was a world champion.
They obviously love their job and the reef and its inhabitants.
You could not do better, as far as I am concerned. Anyone with questions is welcome to send me a private message.
