Renner K. Walker


Renner Walker is an Associate at Levy Konigsberg LLP and focuses his legal practice on class actions, complex environmental litigation, and representing survivors of sexual abuse.

Originally from Des Moines, Iowa, Renner graduated from Drake University Law School in 2012, receiving his J.D. with highest honors and as a member of the Order of the Coif. At Drake Law, he served as Associate Editor of the Drake Law Review and Captain of Drake’s Environmental Law Moot Court Team. Renner also represented indigent criminal defendants pro bono as a student appellate attorney at the Neal and Bea Smith Legal Clinic. He was humbled to be the 2012 recipient of the Justice David and Madonna Harris Award, which is awarded to the graduating Drake Law student who “demonstrates the greatest promise as an advocate, a public servant and a practitioner,” and the 2012 recipient of the Iowa State Bar Association Graduating Senior Award, which is awarded to the graduating law student who is “the most probable successful future leader of the Bar.”

After law school, Renner completed a two-year judicial clerkship for the Honorable Mark S. Cady, Chief Justice of the Iowa Supreme Court, and then spent two years as an Assistant Attorney General in the Iowa Department of Justice, Office of the Attorney General, where he practiced administrative and environmental law. As an Assistant Attorney General, he not only obtained important legal rulings on numerous issues of administrative and constitutional law, he prosecuted teachers who had sexually and physically abused children and students. He fought every day for child victims of sexual and physical abuse, and prosecuted dozens of administrative trials to take abusive and predatory teachers out of Iowa’s classrooms.

Immediately before joining LK, Renner completed a one-year Graduate Research Fellowship in Environmental Law at the Elisabeth Haub School of Law at Pace University, where he also earned an LL.M. in Environmental Law, summa cum laude. During his fellowship, he focused his research on climate change and agricultural law issues.

At LK, Renner has developed a complex litigation and appellate practice, specializing in high stakes arguments on groundbreaking legal issues. As the Senior Associate on LK’s Flint Water Litigation team, Renner works with the Liaison Counsel for individual plaintiffs in the United States District Court for the Eastern District of Michigan and the Lead Counsel for all plaintiffs in actions brought in Circuit Court for Genesee County. In 2018, he briefed and argued the successful opposition to motions to dismiss by more than a dozen defendants in the federal court action. Following months of briefing and several hours of argument, the court denied the defendants’ motions. Now Renner manages discovery in state and federal court for the Flint Water Litigation, spanning several defendants and thousands of lead-poisoned children. He is honored to fight every day for the victims of the largest manmade environmental justice disaster in American history.

In 2017, LK filed Paige et al. v. NYCHA, et al., No. 1:17-cv-07481 (S.D.N.Y.), a first-of-its-kind class action alleging that the City of New York and the New York City Housing Authority (NYCHA) maintained a discriminatory practice by discontinuing legally mandated lead inspections and covering up complaints and findings of lead paint in NYCHA apartments. Renner briefed and argued the successful opposition to the City of New York’s and NYCHA’s motions to dismiss, resulting in a landmark opinion on the Fair Housing Act (FHA) and the Residential Lead-Based Paint Hazards Reduction Act (RLPHRA). The Southern District of New York agreed that the class plaintiffs had successfully pled that NYCHA’s policy of not conducting legally mandated lead inspections and covering up findings of lead paint was a discriminatory practice under the FHA.

Recently, Renner has served as the Senior Associate in a class action lawsuit against Rockefeller University Hospital alleging that, for more than four decades, Dr. Reginald Archibald sexually abused potentially thousands of children. Renner also represents dozens of Dr. Archibald’s victims on an individual, case-by-case basis.

Renner’s appellate practice focuses on representing consumers and workers who have suffered injuries from their exposure to asbestos, such by using contaminated cosmetic talcum powder. In one recent case, Billok v. Union Carbide Corporation, 170 A.D.3d 1388 (3d Dep’t 2019), Renner obtained a new trial based on the trial court’s incorrect admission of highly prejudicial hearsay testimony. More recently, Renner has briefed and argued several appeals before New York’s First Department in New York City. He takes pride in representing workers and consumers at the highest levels.

Renner received his B.A. in Philosophy, English, and History from the University of Iowa in 2007 (Go Hawks!). He is admitted to practice in New York, New Jersey, Iowa, and California. He is also a member of the American Bar Association. Renner lives in Brooklyn with his partner and their two dogs and a cat. In his free time, he is an avid reader and enjoys running.
