I have seen my first diver when I was 10 years old but had to wait till I was 27 years old before I could learn how to dive. After that all fell into place me falling into diving. As of 2015 I have made more then 6000 dives with over 3500 of those being cave dives, over 1000 technical dives and over 1100 hours on CCR Rebreathers on a dozen units.

I am still diving and teaching diving through my MayaTech diving servies company offering a variety of diver, Instructor, diving carrer and Dive Center consulting services through my MattMexico MayaTech web page.

For years I have published more on the ProTec blog, but seldom in paper printed media.

This is a partial list of articles I have published since 1997 in various countries, magazines and books. Almost all articles evolve around the topic of diving.

Since early 2009 I am publishing articles on our ProTec Blog as it gives me the platform to elaborate on a variety of topics.
