Biography

Michael L. Baum, class action attorney serving Greenbrae

Michael L. Baum is a managing partner based in Greenbrae, CA. The practice focuses on Class Action, Litigation, and Personal Injury. Michael has over 41 years of legal experience. Rated 5.0 out of 5 from 3 client reviews. Michael works from Greenbrae, California and takes on class action matters across the region.

Michael L. Baum is the senior managing partner of Baum, Hedlund, Aristei & Goldman. He has successfully led the firm through thousands of wrongful death and personal injury cases stemming from major pharmaceutical drug catastrophes, harmful consumer products, and commercial transportation mass disasters.

He began his career more than 30 years ago, primarily handling airline accidents and other commercial transportation disasters as well as some pharmaceutical product liability litigation. While he oversees all aspects of managing the firm, Michael directs all of the firm’s mass tort litigation, including defective or harmful pharmaceutical drugs, medical devices, herbicides, and consumer products. He also oversees our class actions and whistleblower qui-tam actions.

“Some of our staff were friends long before they started working here and they remain friends after almost three decades of working together. They actually like each other and enjoy making a difference in the lives of others. One of my favorite quotes, which I like to recite to my staff, sums up the work environment we’ve created at the firm: ‘In every job that must be done, there is an element of fun. You find the fun, and – SNAP – the job’s a game!’”

Award-Winning Pharmaceutical Litigation Team

Under Michael’s leadership, Baum Hedlund has developed a reputation as a law firm that can be counted upon to go above and beyond what is needed to get the job done, a firm that has successfully litigated personal injury, wrongful death and consumer fraud cases against major pharmaceutical companies such as Alpha Therapeutic, Armour Pharmaceutical Co., Baxter Health Care Corp, Bayer Corp., Dalkon Corporation, Eli Lilly, Forest Labs, GlaxoSmithKline, and Pfizer.

In 1999, Michael served on the trial team in the only Hemophiliac AIDS case to go before a jury. Michael and the trial team represented Leo and Shirley Dixon, whose son, Ken Dixon, contracted the HIV virus and AIDS allegedly as a result of using hemophilia medication contaminated with HIV.

Evidence presented at trial showed the medication Ken Dixon used was plasma‑derived medication contaminated from the use of high-risk donors with the HIV virus. The jurors found that two of the medication manufacturers, Cutter Biological and Alpha Therapeutics, were strictly liable for product liability, negligence, and fraud. The jurors further found that after Ken Dixon initially was infected with the AIDS virus (which was not known to him at the time), the continued use of the contaminated products further aggravated Ken’s condition, exacerbating and accelerating the development of AIDS. The jury awarded Leo and Shirley Dixon $35.3 million in survival and wrongful death damages. Although the judge overturned the verdict based on a technical issue, the verdict provided essential justice for not only the Dixon family but for hemophiliacs across the country who have suffered and died as a result of their HIV-infected medication.

Fast-forward twenty years later, to find Michael continuing to fight for those injured by Big Pharma products. The National Law Journal recognized Michael and his team as 2018 Elite Trial Lawyers and Pharmaceutical Litigation first place winners for their unprecedented jury verdict against a brand-name drug manufacturer (GSK) for the wrongful death of a man who took a generic form of Paxil.

Groundbreaking Verdicts in Monsanto Roundup Litigation

Michael served on the trial team for three of the first Monsanto Roundup lawsuits to go before juries. In the first trial, Michael and a team of lawyers represented Dewayne “Lee” Johnson, a Benicia, California school district groundskeeper, who alleged exposure to Monsanto herbicides caused him to develop terminal non-Hodgkin lymphoma. A jury in San Francisco unanimously awarded Mr. Johnson $289M in compensatory and punitive damages, finding that Monsanto acted with malice, oppression, or fraud.

In the wake of this groundbreaking verdict, The National Trial Lawyers Top 100 recognized Michael and his team as the 2019 Trial Team of the Year in the Mass Torts category.

The second Roundup lawsuit to proceed to trial, Hardeman v. Monsanto Company, resulted in an $80 million jury verdict. In May of 2019, the third Roundup cancer trial culminated in a historic $2.055 billion verdict in favor of a Bay Area couple who alleged years of exposure to Roundup weed killer caused them to develop non-Hodgkin lymphoma.

Holding Companies Responsible for Aviation Disasters

In addition, his firm is known for successfully resolving major transportation disaster cases against companies such as Airbus, Alaska Airlines, American Airlines, Amtrak, Bell Helicopter Co., Beechcraft, Boeing, Cessna, China Eastern Airlines, Continental Airlines, Delta Airlines, EgyptAir, Ford Motor Co., McDonnell Douglas, Piper, Robinson Helicopter Co., Sikorsky, SwissAir, TACA Airlines, TWA, United Airlines, and US Airways, among many others.

As part of the plaintiffs’ trial team for families who lost loved ones in the United 232 Sioux City, Iowa, crash, Michael found the smoking gun document that showed General Electric’s engineers’ graphs predicting the next DC 10 engine failure, which happened to be the date of the United 232 crash five years later.

“Rigorously investigating and litigating the types of devastating cases we handle on a daily basis requires relentless focus and dedication to our clients’ causes. Approaching things from the perspective that every problem has an optimum solution waiting to be apprehended simplifies our team’s outlook on every aspect of each case we handle.”

Influencing Public Policy

Michael was invited to speak before governmental and regulatory entities on several occasions concerning serious health hazards exposed, in part, due to his firm’s litigation. He testified in Brussels at a public hearing before the European Parliament’s Special Committee Hearing on the EU’s authorization procedure for pesticides (PEST), concerning environment impacts of pesticides, including Monsanto’s Roundup weed killer. He and Robert F. Kennedy, Jr. delivered the keynote address to members of the European Green Party at the start of their pesticides hearing during that same trip. He and his partner, R. Brent Wisner, also briefed members of Parliament of Canada’s Green Party about the first Roundup cancer verdict we helped obtain, as well as the evidence we presented at that trial.

Medical officials from foreign governments in countries such as Ireland, Japan, Russia, and Taiwan have sought Michael’s advice and assistance with their countries’ public policies concerning consumer drug safety. They’ve done so after becoming aware of Michael’s impressive understanding of biomedical research, clinical trials, statistics, the pharmaceutical industry and marketing, as well as his firm’s successful and effective discovery procedures and extensive work with experts on complicated scientific issues related to Baum Hedlund’s pharmaceutical litigation.

Career Highlights

Among his many achievements, accomplished with the help of his team, Michael is most proud of:

- Being recognized, along with his firm, as a national leader in the antidepressant Paxil, Prozac, and Zoloft suicide litigation; - Working to bring about the black box suicidality warning for children and young adults, now on most antidepressant labels; - Helping spur funding for the Ricky Ray Hemophilia Relief Fund Act of 1998, which was made part of the negotiated settlement to help scores of hemophiliacs infected with HIV by contaminated medication; - Arranging for the face-to-face presentation between pharmaceutical company executives and dozens of hemophiliac families that got to say, person by person, holding before and after photos of themselves or departed loved ones, how the hemophilia-AIDS epidemic, and the manner in which the companies caused and covered it up, impacted their lives; - Being one of the leaders in the fight against federal preemption, a doctrine pushed by the pharmaceutical industry to wipe out consumers’ rights to sue drug companies for injuries caused by their drugs (Preemption was finally defeated in 2009 with the Supreme Court’s ruling in Wyeth v. Levine); - Creating the first class action ever filed against an SSRI-antidepressant manufacturer, ending with the successful resolution of more than 3,000 Paxil injury cases; - Finding “needles in haystacks” and “smoking guns” in document productions, such as GE engineers’ graphs predicting the next DC 10 engine failure which mirrored the date of the United 232 crash five years later, an internal study linking SSRIs to cardio birth defects, or documentation of company programs to ghostwrite medical journal articles for academic opinion leaders to give the appearance of objective science when actually serving marketing objectives to increase prescriptions, i.e. disguised advertising; - Negotiating the first official public apology by an airline for the 2003 Air Midwest Flt. 5481 Charlotte, North Carolina crash; - Eliminating California law that protected tobacco companies from lawsuits. For many years, the statute of limitations was considered to begin to run from the date the plaintiff knew or should have known that he/she was addicted to tobacco. This effectively barred plaintiffs, many of whom began smoking in their teens, from suing. Now, the statute of limitations runs when the plaintiff’s physical injuries are (or reasonably could be) discovered; - Developing a rigorous, skillful, and technical method for locating hard-to-find manufacturer documents in order to successfully litigate against major pharmaceutical companies, positioning his firm as a leader in the fight to increase public health and safety; - Creating coalitions of activists, attorneys, and Baum Hedlund staff, who work together to resolve global problems caused by harmful and defective drugs, which no individual could accomplish alone.

“We have adopted Margaret Mead’s philosophy, ‘Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.’”

Michael has served on numerous trial teams and plaintiffs’ steering committees in mass tort litigation involving pharmaceutical product liability cases as well as major airline crashes.

He has an AV® 5.0 out of 5 Peer Review Rating through Martindale Hubbell, and is listed in The Best Lawyers in America®, Bar Register of Preeminent Lawyers, Southern California Super Lawyers, Who’s Who in American Law, and Aviation Counsel Magazine’s List of Recommended High Flyers.

In his spare time, Michael enjoys spending time with his family, playing foosball, softball, volleyball, and boogie boarding.
