OLSON GRIMSLEY CELEBRATES TWO YEARS

Olson Grimsley Kawanabe Hinchcliff & Murray LLC is an impact trial and appeals law firm founded in the fall of 2023 to hold the powerful to account.

In just two years, we’ve taken seven cases to trial, argued three appeals, and obtained more than $80 million in judgments for our clients. We won the nation’s first trial against preterm infant formula makers for the harms their product caused and are gearing up to do it again. Our pro bono cases have tackled urgent issues facing our country: we sued Donald Trump to enforce the 14th Amendment in Colorado, taking the ballot access case all the way to the U.S. Supreme Court. And we just sued ICE to stop warrantless arrests. We don’t just litigate. We lead.

In 2025, we added three associates:

Bianca Miyata led the Colorado Attorney General’s Office’s efforts to protect kids against big tech.

Meredith Wheeler is a Rhodes Scholar who finished her Ninth Circuit clerkship after serving as a Public Defender in Colorado.

Noah Nix completed his clerkships at the Tenth Circuit and Colorado Supreme Court.



SOME HIGHLIGHTS FROM OUR SECOND YEAR

Standing Up for Student-Athletes


OG partnered with Korein Tillery to represent 300+ former college athletes who opted out of the NCAA settlement. Our clients allege the NCAA and Power 5 Conferences violated antitrust laws, and their individual claims will now proceed in federal court in Colorado. Read more from The New York Times. 



Protecting Victim of Enfamil on Appeal


OG is lead appellate counsel before the Illinois Court of Appeals, seeking to uphold a $60 million verdict against Mead Johnson, maker of Enfamil Premature Infant Formula. An Illinois jury found the cow’s-milk formula caused necrotizing enterocolitis in premature infants—the first trial of its kind nationwide. OG led trial efforts with Keller Postman and The Cates Law Firm. Read more from ABC News.

Attacking Junk Fees


OG partnered with Towards Justice, Edelson, and Cadiz Law to challenge Greystar—the nation’s largest apartment manager—attempts to charge tenants illegal “junk fees” that inflate housing costs. After OG’s argument, the Colorado Supreme Court consolidated the cases before the district judge OG requested. Read more from Law360.

Fighting for Tenants


OG was also set to argue Curran v. Home Partners Holdings before the Colorado Supreme Court when the case settled days prior. We represented tenants who alleged that lease terms with a Blackstone subsidiary violated the warranty of habitability and the Colorado Consumer Protection Act.

Seeking Justice for Terrorism and Human-Trafficking Victims


OG and Sparacino PLLC represent hundreds of victims of overseas terrorism and human trafficking in four federal cases. After OG’s oral argument, the court denied the motion to dismiss, finding federal antitrafficking law covers US companies with global operations. Read more from The Wall Street Journal.

ADVANCING THE PUBLIC INTEREST

Defending School Policy Ensuring All Students can Fully Participate


After a national religious advocacy group sued the second largest school district in Colorado over its policy for including all students on overnight trips, OG secured a complete victory, with all claims dismissed, upholding its commitment to a safe and inclusive learning environment. Read more from Colorado Public Radio News. 

Protecting Immigrants


OG, alongside ACLU Colorado and Meyer Law Office, sued the Trump Administration to stop mass warrantless ICE arrests that violate federal law. The suit seeks to prevent ICE from arresting Coloradans without first determining whether the individual poses a flight risk. OG led the preliminary injunction hearing at the end of October and awaits a ruling from the Court. Read more from Law360.

Gun Safety


OG represented Everytown for Gun Safety, Giffords Law Center, and other advocacy groups and academics in a merits-stage amicus brief before the U.S. Supreme Court in Smith & Wesson Brands, Inc. v. Estados Unidos Mexicanos. The brief urged the Court to narrowly resolve the second question presented under the Protection of Lawful Commerce in Arms Act—and the Court’s opinion followed that approach.

Law Firm Partners United


OG represents Law Firm Partners United Inc. (LFPU), an association of 850+ AmLaw 200 partners and shareholders dedicated to defending lawyers’ constitutional right to choose their clients and advocate without government reprisal. OG and Zimmer, Citron & Clarke, working pro bono, filed amicus briefs challenging Executive Orders targeting law firms.

WHAT’S ON THE HORIZON



Leading Similac Product Liability Trial


OG is lead trial counsel in a consolidated four-plaintiff case against Abbott Laboratories, maker of Similac Special Care preterm formula, alleging it caused necrotizing enterocolitis in premature infants. This will be the first multi-plaintiff preterm infant formula trial in the nation and the first in Cook County, Illinois. OG is working with Keller Postman.


Antitrust Class Action


OG and Freed Kanner London & Millen filed a class-action antitrust suit alleging that major archery retailers, manufacturers, and trade associations conspired to fix product prices. OG won its argument to have the Judicial Panel on Multidistrict Litigation locate the MDL in Colorado—the first in Colorado federal court in more than 15 years. Read more from Reuters.
