A new lawsuit against Cedars-Sinai and former OB-GYN Barry J. Brock was filed by 112 women, alleging sexual abuse spanning more than 40 years. The patients allege that Cedars-Sinai covered up the abuse while allowing Brock to continue exploiting patients.

The lawsuit is the most recent in several that have been filed against Brock and Cedars-Sinai. The 112 plaintiffs join an existing 218 former patients who have already filed litigation against Brock and the health center, bringing the total number of alleged victims to 330.

The most recent lawsuit was filed by Arias Sanguinetti Wang and Team LLP and the DiPietro Law Firm.

“Cedars-Sinai had both a moral and legal duty to protect its patients,” said Mike Arias, managing partner of Arias Sanguinetti. “Instead, the institution knowingly enabled a serial predator and prioritized its reputation over the safety of women who trusted them with their care. As more and more brave women continue to come forward, it becomes painfully clear how deeply Cedars failed those in its care. We will continue standing with survivors and fighting to hold the institution fully accountable.”

The combined action against Cedars-Sinai and Brock is among the largest sexual abuse cases ever filed against a California medical institution. The firms are seeking injunctive relief requiring Cedars-Sinai to implement systemic reforms to prevent future abuse.

“Each of these women were placed in a position of vulnerability under the guise of medical care,” said Anthony T. DiPietro of the DiPietro Law Firm. “They are coming forward now to hold the institution accountable, expose the wrongdoers and ensure that no other patient has to endure the same trauma.”

The allegations against Brock include sexual misconduct, rape and sexual assault. The lawsuits allege that the abuse dated back to the 1980s, when Brock began working at Cedars-Sinai. Brock has denied the allegations.

Cedars-Sinai banned Brock from practicing at the hospital in September 2024.

“The type of behavior alleged about Dr. Barry Brock is counter to Cedars-Sinai’s core values and the trust we strive to earn every day with our patients. Dr. Brock no longer has privileges to practice medicine at Cedars-Sinai,” a statement from the medical center read. “We recognize the legal process must now take its course, and we remain committed to Cedars-Sinai’s sacred healing mission and serving our community.”

Brock surrendered his medical license in May 2025, following an accusation of negligent care from the Medical Board of California. According to the lawsuits, Brock is also under criminal investigation.
