Dozens of patients file suit against former OB-GYN and Cedars-Sinai, alleging misconduct
Thirty-five women are suing a Beverly Hills obstetrician-gynecologist, Cedars-Sinai Medical Center and other medical practices where the doctor worked, alleging decades of sexual and medical misconduct that the health facilities enabled and concealed.
The lawsuit, filed late Monday in Los Angeles County Superior Court, alleges that Dr. Barry Brock had, for years, made lewd and unsettling comments to patients; groped their breasts and genitals during medically unnecessary exams, sometimes without gloves; and engaged in “female genital mutilation” by giving women unneeded sutures, among other reported misconduct.
The suit also alleges the longtime physician denied caesarean sections to patients who needed them.
Brock has repeatedly denied any wrongdoing or sexual misconduct, saying he had never touched a patient inappropriately or made sexually suggestive or harassing remarks.
The longtime OB-GYN said in a statement Tuesday that the allegations in the lawsuit were false and outrageous, calling them “flat-out lies, made up events that never happened, exaggerated and fabricated statements, and worse.”
Attorneys “have made it seem as if I was grooming patients even by just speaking to them, insanely claiming that suturing a patient after childbirth is genital mutilation, and saying that my standard vaginal exams and pap smears were ‘sadistic,’” Brock said.
He said that patient records and witnesses “will help me prove the truth of what happened here.”
Cedars-Sinai said in a statement Tuesday that the kind of behavior alleged about Brock, who is no longer practicing medicine at its facilities, is “counter to Cedars-Sinai’s core values and the trust we strive to earn every day with our patients.”
“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.”
The doctor is also facing an accusation before the Medical Board of California, where he is accused of committing “repeated negligent acts.” According to the official complaint, Brock failed to give a patient enough pain medication while treating her for a miscarriage, and failed to properly clear material from her uterus, among other accusations.
In a statement, Brock said the events outlined in the accusation were not an accurate description of his treatment of the patient and that some allegations were “completely inconsistent with my practices.”
For instance, Brock said he could not imagine refusing to address severe pain suffered by a patient. “Based on what I know of my care and treatment of this patient,” he said, “I will successfully defend my treatment as being within the standard of care.”
Brock, 74, said he had been an attending physician at Cedars-Sinai since the early 1980s, and had never before faced an accusation from the medical board.
He left its physician network in 2018 but retained hospital privileges at Cedars-Sinai while working in private practice at Rodeo Drive Women’s Health Center and Beverly Hills OB/GYN, which were also named as defendants in the lawsuit. Both organizations had yet to respond to requests for comment Tuesday.
In July, Cedars-Sinai said it had suspended Brock’s hospital privileges after receiving “concerning complaints” from his former patients. A few months later, his hospital privileges were terminated.
At that time, a spokesperson for Cedars-Sinai said that privacy laws prohibited the medical center from confirming the existence of any patient complaints or disciplinary action taken against Brock before this year.
The lawsuit alleges that both patients and medical staff reported concerns about Brock to Cedars-Sinai long before the complaints that led to the termination of his hospital privileges.
Cedars-Sinai administrators received “ample and repeated warnings” about his misconduct and abuse of patients through past lawsuits, as well as complaints to the state medical board and to the health system itself, the lawsuit alleged. Yet the medical center and other defendants continued to “expose more unsuspecting female patients to a known serial sexual predator,” the suit alleged.
Plaintiffs are represented by a legal team that includes Anthony T. DiPietro, an attorney who has also represented patients of convicted sex offender Robert Hadden, formerly a gynecologist at Columbia University, and Mike Arias, who like DiPietro has represented patients of former USC gynecologist George Tyndall.
The complaint details allegations from 35 former patients ranging in age from their 20s to their 60s. Some saw Brock only once and refused to see him again, while others were treated by him repeatedly over a period of years. The timing of their care ranges from the mid-1980s to this year, according to the complaint.
Nearly a dozen patients alleged unnecessary suturing or crude comments about it: Brock told several plaintiffs he inserted an “extra stitch” in their perineal areas to make them “tighter” after childbirth, the lawsuit said.
In one instance, according to the lawsuit, Brock said, “I’m going to sew her up virgin-tight” in front of a woman’s husband and parents after childbirth. In another, Brock told a woman that she had not suffered any tearing, but told her husband, “Don’t worry, dad, I’ll throw a stitch in there for you,” and proceeded to suture her without her consent, the lawsuit alleged.
Some suffered ongoing pain or urinary complications after “this barbaric and entirely unnecessary form of female genital mutilation,” the lawsuit said. Doctors for one patient described the stitching as “the equivalent of a female circumcision,” the lawsuit said.
Brock told The Times that he performed perineal suturing only if there was a laceration, and that if he did so, “there was always consent.”
The lawsuit also included allegations of violent and threatening behavior. One former patient alleged that Brock “violently thrust” a speculum into her vagina, opened it and “proceeded to pump the instrument in and out of her, simulating intercourse.”
The woman said she reported the experience and other concerning encounters with Brock to an executive at Rodeo Drive Women’s Health Center, where Brock worked at the time. No action was taken against him, according to the lawsuit.
Brock told The Times that he had never forced in a speculum and called the claim about simulating intercourse “complete nonsense” that “appears to be a tricky lawyer way to make an appropriate medical exam seem like an assault.”
In the lawsuit, two women alleged that he forced them to feel his erection. One said he had “proceeded to rub his erect penis against her hand” while she was alone with him in an exam room, the lawsuit said.
Another alleged that while she was in labor, Brock walked in and put her foot on his erection, then grabbed her foot again when she tried to move it away.
Brock, in his statement, said he had “NEVER NEVER told any patient to touch me in any way,” nor touched patients inappropriately, and had never had an erection during an exam.
The lawsuit also alleged that Brock forced patients to undergo sensitive physical exams even after they refused. A decision to do a pelvic or breast exam should be a shared one between a physician and a patient, the lawsuit said, and “such invasive procedures should never be performed without the patient’s knowledge, understanding, and consent.”
In one case, the lawsuit said, Brock pulled down the pants of a woman who refused a vaginal examination in front of her daughter and “was so aggressive that [the woman] immediately ran out of the room in tears.”
Brock, in his statement, denied ever pulling down the pants of a patient and said that if a woman wanted to refuse a Pap smear or pelvic examination, that would be her right. He also said he always wore gloves to protect himself and patients during pelvic exams.
Another patient alleged that Brock ignored her when she said a breast exam was unnecessary. Instead, the complaint alleges, he unhooked her bra, squeezed her breasts and told her, “You have perfect breasts. Does your husband tell you that?” She was one of five women who said he removed their bras without consent before touching their breasts, according to the complaint.
Other patients alleged that Brock refused to leave the room as they undressed or denied their request for a hospital gown, requiring them to go through examinations naked.
Brock told The Times that he either leaves the room when a patient undresses or, if a patient in a hurry requests it, turns while they change behind a curtain, and “there never would be a case where a gown was not provided upon request.” He said if a patient turned down a breast exam, he would not perform one.
The doctor added that on a few occasions when a patient had not removed their bra before putting on a gown, he had assisted a patient in unclasping it for a breast exam. “This was not done for any improper purpose and was done that way so the patient did not need to take off the gown,” Brock said.
In the lawsuit, many patients described sexual remarks: One said Brock told her that her vagina looked “ripe” and peppered her with invasive questions, such as asking whether her partner would ejaculate on her body during sex, according to the lawsuit. Several patients noted that while examining the women’s genitals or breasts, Brock commented on how “lucky” or “happy” their partners must be, the suit said.
Brock denied making such remarks. “I have never spoken those words,” he said.
The lawsuit alleges that Cedars-Sinai was repeatedly informed about concerns with Brock. One patient who saw him between 2011 and 2013 reported his behavior to office staff and asked to switch to a different doctor, according to the lawsuit. Another who saw him in 2018 and 2019 informed her regular physician, who was also affiliated with Cedars-Sinai, about his actions, the suit said.
Another former patient, herself an employee of Cedars-Sinai at the time, filed a formal complaint with the medical center after a 2017 prenatal appointment in which Brock allegedly groped her breasts “under the guise of medical care” and made inappropriate comments to her and her husband, according to the suit.
Though she was told there would be consequences for Brock — who was in Cedars-Sinai’s physician network at the time — she heard nothing more from the medical center, the complaint states.
The lawsuit said another patient who tried to report misconduct to Cedars-Sinai earlier this year was initially told that the medical center wouldn’t take action because the doctor was in private practice.
She then contacted Beverly Hills OB-GYN, which had referred her to Brock after her usual physician was unavailable. When she received no response after sharing her experience, the woman lodged a formal, written complaint with Cedars-Sinai by email, according to the suit. It was only then, the lawsuit said, that her complaint was taken seriously and Brock had his hospital privileges suspended.
A Cedars-Sinai spokesperson told The Times in September that the hospital system had terminated clinical privileges for Brock after an investigation and reported the matter to the state medical board.
Brock, however, said he had surrendered his privileges without any “fact finding” or “hearing on the merits” of the allegations under investigation. In August, he had informed patients he would retire at the end of the month due to the “uncertainty of how long this process will take.”

Lyrids Meteor Shower: How to Watch, Peak Time and Weather Forecast
Our universe might be chock-full of cosmic wonder, but you can observe only a fraction of astronomical phenomena with the naked eye. Meteor showers, natural fireworks that streak brightly across the night sky, are one of them.
The latest observable meteor shower will be the Lyrids, which has been active since April 14 and is forecast to continue through April 30. The shower reaches its peak April 21 to 22, or Tuesday night into Wednesday morning.
According to NASA, the Lyrids are one of the oldest known meteor showers, and have been enjoyed by stargazers for nearly 3,000 years. Their bright, speedy streaks are caused by the dusty debris from a comet named Thatcher. They appear to spring from the constellation Lyra, which right now can be seen in the eastern sky at night in the Northern Hemisphere.
The moon will be about 27 percent full tonight, appearing as a thick crescent in the sky, according to the American Meteor Society.
To get a hint at when to best watch for the Lyrids, you can use this tool, which relies on data from the Global Meteor Network. It shows fireball activity levels in real time.
And while you gaze at the heavens, keep an eye out for other stray meteors streaking across the night sky. Skywatchers are reporting that the amount of fireballs is double what is usually seen by this point in the year.
Where meteor showers come from
There is a chance you might see a meteor on any given night, but you are most likely to catch one during a shower. Meteor showers are caused by Earth passing through the rubble trailing a comet or asteroid as it swings around the sun. This debris, which can be as small as a grain of sand, leaves behind a glowing stream of light as it burns up in Earth’s atmosphere.
Meteor showers occur around the same time every year and can last for days or weeks. But there is only a small window when each shower is at its peak, which happens when Earth reaches the densest part of the cosmic debris. The peak is the best time to look for a shower. From our point of view on Earth, the meteors will appear to come from the same point in the sky.
The Perseid meteor shower, for example, peaks in mid-August from the constellation Perseus. The Geminids, which occur every December, radiate from the constellation Gemini.
How to watch a meteor shower
Michelle Nichols, the director of public observing at the Adler Planetarium in Chicago, recommends forgoing the use of telescopes or binoculars while watching a meteor shower.
“You just need your eyes and, ideally, a dark sky,” she said.
That’s because meteors can shoot across large swaths of the sky, so observing equipment can limit your field of view.
Some showers are strong enough to produce up to 100 streaks an hour, according to the American Meteor Society, though you probably won’t see that many.
“Almost everybody is under a light-polluted sky,” Ms. Nichols said. “You may think you’re under a dark sky, but in reality, even in a small town, you can have bright lights nearby.”
Planetariums, local astronomy clubs or even maps like this one can help you figure out where to go to escape excessive light. The best conditions for catching a meteor shower are a clear sky with no moon or cloud cover, sometime between midnight and sunrise. (Moonlight affects visibility in the same way as light pollution, washing out fainter sources of light in the sky.) Make sure to give your eyes at least 30 minutes to adjust to seeing in the dark.
Ms. Nichols also recommends wearing layers, even during the summer. “You’re going to be sitting there for quite a while, watching,” she said. “It’s going to get chilly, even in August.”
Bring a cup of cocoa or tea for even more warmth. Then lie back, scan the sky and enjoy the show.
Where weather is least likely to affect your view
Storm systems sweep across the country in early spring, and some will be obscuring skies tonight. But there will still be plenty of areas with clear skies, particularly in parts of the central United States.
“The best spot is going to be in the Upper Midwest,” said Rich Bann, a meteorologist with the Weather Prediction Center.
Minnesota, Wisconsin and Iowa will offer especially good sky-viewing weather and a beach on the Great Lakes could be a nice spot to look up at the stars.
But don’t expect to view the show from Chicago, as Illinois could see some thunderstorms. The weather will be better in the Northern and Central Plains, particularly the eastern Dakotas.
High, wispy clouds are expected over the Ohio and Tennessee Valleys and into parts of the Mid-Atlantic. But, Mr. Bann said, “you may be able to see some shooting stars through thin clouds.”
Clouds will be draped across much of the Southeast and the Northeast, though there could be some clearing in Florida, Georgia, the Carolinas and Virginia. Remember, the meteors could be visible all night long. If you look outside and see clouds, try again later.
Catching the spectacle will be challenging across much of the West, particularly from Washington into Northern California, where a storm system is bringing rain and snow. That system will move east overnight.
There are likely to be some pockets of clear skies at times across southern Nevada, northwest Arizona and southwest Utah, Mr. Bann said.

FBI probes cases of missing or dead scientists, including four from the L.A. area
WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.
“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.
The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.
“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.
President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”
Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.
A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.
Two other Los Angeles scientists are part of the string of deaths and disappearances.
On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.
On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.
Snyder has been charged with murder.
There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.
A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.
“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”
Representatives from Caltech, which manages JPL, did not immediately respond to a request for comment.

What’s in a Name? For These Snails, Legal Protection
The sun had barely risen over the Pacific Ocean when a small motorboat carrying a team of Indigenous artisans and Mexican biologists dropped anchor in a rocky cove near Bahías de Huatulco.
Mauro Habacuc Avendaño Luis, one of the craftsmen, was the first to wade to shore. With an agility belying his age, he struck out over the boulders exposed by low tide. Crouching on a slippery ledge pounded by surf, he reached inside a crevice between two rocks. There, lodged among the urchins, was a snail with a knobby gray shell the size of a walnut. The sight might not dazzle tourists who travel here to see humpback whales, but for Mr. Avendaño, 85, these drab little mollusks represent a way of life.
Marine snails in the genus Plicopurpura are sacred to the Mixtec people of Pinotepa de Don Luis, a small town in southwestern Oaxaca. Men like Mr. Avendaño have been sustainably “milking” them for radiant purple dye for at least 1,500 years. The color suffuses Mixtec textiles and spiritual beliefs. Called tixinda, it symbolizes fertility and death, as well as mythic ties between lunar cycles, women and the sea.
The future of these traditions — and the fate of the snails — are uncertain. The mollusks are subject to intense poaching pressure despite federal protections intended to protect them. Fishermen break them (and the other mollusks they eat) open and sell the meat to local restaurants. Tourists who comb the beaches pluck snails off the rocks and toss them aside.
A severe earthquake in 2020 thrust formerly submerged parts of their habitat above sea level, fatally tossing other mollusks in the snail’s food web to the air, and making once inaccessible places more available to poachers.
Decades ago, dense clusters of snails the size of doorknobs were easy to find, according to Mr. Avendaño. “Full of snails,” he said, sweeping a calloused, violet-stained hand across the coves. Now, most of the snails he finds are small, just over an inch, and yield only a few milliliters of dye.
