Well if she looks amazing at 63 that's enough credentials for me. If she was an old hag I would discount her credibility.
Recently there was an issue with a Venezuelan doctor working in SD which Nuria says is not a real doctor. On the first part, what Nuria claimed sounded very convincing, but a few days later another Venezuelan living in SD (journalist by profession) investigated the case of the Venezuelan doctor and it turns out she is a doctor that graduated from the Venezuelan university that she said and is registered in Venezuela with having that title. He also said other things including that journalists should always tell the truth. Then a few days later another episode of Nuria further sunk the Venezuelan doctor's reputation by claiming, among other things, that her further investigation revealed that the Venezuelan doctor had a university degree from Venezuela in marketing rather then medicine among other things. I don't know what followed after that.
Here is the Venezuelan guy that investigated and found that she is registered as a doctor in Venezuela, graduated from the Venezuelan university she said. At a certain poibt he show that.
Here is the rebuttal of Nuria.
She isn't allowed to practice medicine in the DR because all professionals need an exequatur which is emitted by the MESCYT. Until that is not acquired, no one can practice their profession in the DR. But the series of the Nuria show was about false titles, that means people that didn't graduated from any university and were working as professionals of such type in the DR with diplomas as "evidence" that were not actual diplomas. You can't get a legitimate exequator from the MESCYT by submitting false diplomas or even copies, they must be originals.
It leaves one wondering what happened here, at least concerning the legitimacy of her university diploma. Everything else presented by Nuria seems to be correct.
There was the case of Elizabeth Silverio from Antigua & Barbuda in the Lesser Antilles that practiced as a professional in the DR, yet everything about her claims and "degrees" were fake. One of the universities Elizabeth Silverio claim she graduated from is in Florida and when Nuria contacted that uni, they confirm that not only Elizabeth Silverio isn't graduated from there, but they never had her as a student. lol That is slightly different from the Venezuelan doctor as her diploma is legitimate even if she doesn't have the exequatur to practice in the DR.
