Reading and reviewing their website, they have instructors from a wide range of agencies. Would the doctor say I want an instructor that uses the American Heart Association's guidelines? Or would they receive a Red Cross one year and then a National Safety Council for their following certification? Or does this company take all of the thoughts of the three or more and come up with their own guidelines? If their own guidelines who is insuring them? If a patient dies in the dental office and the dentist states they were taught by "this" company, does this company have insurance on their staff? If an instructor was from the American Heart Association, the AHA would back the instructors training as they have research to back them and I am sure a lot of lawyers. I would be very concerned that if I was a dentist, I would have to hire a lawyer just to see if the instructors qualifications and their way of teaching would hold up in court?  Hopefully, someone can update the website to make it more clear.
