In February 2025, Zimmer, Citron & Clarke's Eric Citron argued the opposition to the government's motion to dismiss for lack of subject matter jurisdiction under the FTCA in In re: Aqueous Film-forming Foams Products Liability Litigation, in federal district court in South Carolina.  The district court issued a decision just a few weeks later denying the government's motion in large part and allowing the MDL to proceed. 

Founding Partner David Zimmer was quoted in a New York Times piece on the recent phenomenon of big law firms backing away from pro bono work for fear of incurring the wrath of the Trump Administration. As David Zimmer explains, small firms like Zimmer, Citron & Clarke have been approached to fill the gap.

Two former Goodwin Procter partners and an experienced Washington, D.C., appellate lawyer have opened a boutique law firm—Zimmer, Citron & Clarke—that aims to fill a niche: representing plaintiffs in high-stakes appeals.

Zimmer Citron & Clarke’s David Zimmer and Edwina Clarke say major law firms need to band together and speak out against Trump targeting lawyers—their fiduciary duty to clients complicates the issue, but it’s no excuse for silence.

Two Goodwin Procter appellate attorneys, along with a former Gupta Wessler LLP lawyer, have branched out to start their own plaintiff-side appellate boutique, the attorneys announced on Tuesday.

A pair of Goodwin partners in Boston are launching an appellate litigation boutique. […] “Our goal is to serve as a strategic partner for plaintiff-side trial firms as they navigate complicated legal issues in trial courts and courts of appeals,” Zimmer said.

FOR YOUR RADAR — David Zimmer, Eric Citron and Edwina Clarke are launching a litigation firm: Zimmer, Citron & Clarke. Zimmer and Clarke previously built Goodwin Procter's Supreme Court and appellate practice. Citron previously practiced at Gupta Wessler and Goldstein & Russell.

Three accomplished appellate attorneys have come together to form Zimmer, Citron & Clarke, a boutique firm focused on providing sophisticated legal advocacy for plaintiffs in high-stakes litigation.
