Rosenstein is a Canadian cave and technical instructor who moved to Mexico in 2016 and owns Beyond Diving in Playa del Carmen, specialising in full cave training. One pattern stands out: a ScubaBoard poster asked about planning full cave training in Mexico recommends him on the strength of having done a cavern course with him, gone away for several years, and come back to him specifically for full cave. Choosing the same instructor again after a long gap says more than most single reviews. Beyond that, the descriptions are consistent and unshowy — patient, methodical, unwilling to rush a student through, and genuinely invested in getting people certified safely rather than quickly. He appears in ScubaBoard threads on cavern diving in the cenotes as well as full cave. Less has been written about him than about some of the region's instructors, so ask for references from recent full cave students.
