Testimonials

On recommendation of a friend, we contacted Tillmann. It was important to us to have our first diving experience with an experienced instructor who also speaks our language. We were not disappointed. With a lot of patience and humor he explained to us how everything works and also took our son (15) the fear of open water. We also experienced dives in a cenote. For us it is clear that the next vacation will be a diving vacation.

On my first trip to Mexico with a good friend that was doing an underwater filming project, I was recommended to get my diving license with Tillmann. Excellent instructor, very friendly, competent and helpful. I was lucky enough to have private lessons and was extremely happy. I can definitely recommend Tillmann!
