Yes and Yes!
German Yanez Mendoza is Yucatech in Cozumel, and the NACD safety officer for the Cozumel cave systems. He is very willing to guide and teach in the mainland caves, too.
Our group had 2 full-Cave certified divers who were looking for a guide to introduce them to the Cozumel caves, and 2 experienced divers who wished to take the NACD Cavern Diver class.
The Cave divers were thrilled by German's knowledge and enthusiasm. German has worked closely with the University in Cozumel that is researching the unique organisms living in these caves. He is one of the authors of a recently published article about this. German went out of his way to work with our schedule, including driving us to the caves, bringing doubles for the cave guys to rent, and doing our class lecture at our hotel. My buddy and I loved the Cavern class and the whole experience with German.
German is a top-notch professional, brimming with knowledge and love of the Yucatan caves. I can't wait to return and take the Intro to Cave class with him.
Lynne, I'm delightfully jealous that you'll be diving with him in March.
