I will humbly modify my initial post as soon as the site owner of dive buddy tells me he has seen a certification for the individual mentioned from DRI (Dive Rescue International), LGS (Lifeguard Systems), ERDI (Emergency Response Diving International), PADI Master Instructor, as well as a proof of membership for IADRS (International Association of Dive Rescue Specialists) or the CAST dive team. The founder and leader of the CAST Team is well aware of the individual posing as a member of his team, and the founder of the IADRS is also aware of this individual. Playing musical chairs with certification agencies on a profile does not add to one`s credibility. All organizations listed above have been listed on this member`s posts or in different iterations of his profile.
