Described by Chambers USA as a “the perfect litigation boutique” and the “Go-to firm for bet-the-farm litigation,” Hueston Hennigan LLP is “enjoying meteoric success.”

Since Hueston Hennigan opened its doors in 2015, it has established itself as a top, nationally recognized trial boutique known for finding a way to win in the highest-stakes litigation, trials and white collar defense cases.

Our lawyers approach cases differently than most litigation firms: from day one, we treat each matter as though it will go to trial. This emphasis on trial readiness inspires us to bring creative strategies to each matter. By developing a deep understanding of the facts, the context, and the law relevant to each case, we can aggressively litigate without relying on a rulebook. Our focused preparation and forceful posture in the first 90 days help us achieve the most successful and cost-effective outcomes for our clients.

This approach works because we don’t function like a traditional, hierarchal law firm. Instead, we train our teams to think like “outside GCs.” Since each client is a firm client, not a client of any individual partner, every lawyer is focused on comprehensively, creatively, and collaboratively solving their clients’ unique problems.
