My mother was a patient of this fraud for 20 years and his negligence nearly had her die in the ICU. Completely abandoned her and ignored her missing critical symptoms. Avoid this crook at all costs.

I have been going to Dr. Atadero for as long as I cam remember and he has always taken the extra time to make sure I get over whatever it is I come down with. His hospital visits for me were above and beyond and it truly shows the type of person he is.

Unbeknownst to me at the time, Arsenio Atadero was the "attending physician" at a "bad fix" on a broken ankle of mine. His wife and he bought out my former PCPs practice. And apparently due to paranoia of a non-existent malpractice suit, his wife put me on The second most deadly drug cocktail, then denied the common ADRs were caused by the deadly drug cocktail. Next the Ataderos had me gas lighted by psychiatrists who misdiagnosed, defamed and poisoned me for years with drug cocktails known to cause anticholinergic toxidrome, all while both Jennifer and Arsenio denied the drugs could be the cause of my illness. Eventually, some decent and disgusted nurses in their former office handed over my family's medical records, and I also learned that Jennifer had lied to me, and had been covering up medical evidence of the sexual abuse of my small child for years, too. Plus, neither of my children had been properly immuanized. Find a non-paranoid, competent, and ethical doctor instead.

I have been in to see him several times for myself and my daughter over the last few years and I genuinely like him. He is a very kind, calm, and caring person and is never in a rush to move on to the next patient.
