Advanced Diver Mexico, Playa del Carmen

I highly recommend cave training with Marcia, his instruction is very practical and no-nonsense, focusing on time in the water and tweaking your configuration so you get the best out of the course, your equipment, and the dives. Everything that he teaches you has a reason behind it and Marcia is very well versed at being able to explain that reasoning so that you clearly understand the information. When he is finished explaining a topic you have not only learned the information but you also know why. Overall I would recommend Marcia to anyone who is looking for an instructor that will focus on you understanding the reasons and rationales behind everything you do. Believe me, it will stick to you for the rest of your whole diving career.

Spent 5 days cavern diving in the Cenotes with Marcia and Joshua. Both good guys and very knowledgeable to keep you safe and ensure you get the most out of your dives. Most importantly the diving was always very relaxed and the days ran smoothly. I didn't have time to do a cave course, but I'd have every confidence in Marcia's ability to provide top notch training.
