However The Jerusalem Post warned in 2014 (and 2015) that he's an impostor.
The Health Ministry issued a warning yesterday about a man named Adiel Tel-Oren who presents himself as a physician but is an imposter.
He is “unlicensed to practice medicine in Israel. He treats patients in his clinic while using preparations that are liable to endanger health and are not approved for use,” the ministry said on Thursday.
The ministry says that Tel Oren “admitted to us while he was taped that he is not a licensed medical doctor,” that he is not recognized as an MD in either Israel or the US and that the authorities suspect his studies’ diploma from Russia is “counterfeit.”
