About HKM Employment Attorneys LLP · New York

HKM Employment Attorneys LLP is a national employee-side employment law firm with a New York office located at 39 Broadway, Suite 2430, New York, NY 10006 (phone 212-451-9533). Founded in Seattle in 2007 by Donald W. Heyrich alongside Daniel Kalish and Patrick McGuigan, the firm has grown into one of the largest employee-only employment law practices in the United States, representing workers in discrimination, harassment, wage theft, wrongful termination, employment contracts, severance, retaliation, and class action matters. According to the firm's website, HKM attorneys have recovered more than $500 million for clients since 2003, with the New York team staffed by bilingual (English/Spanish) attorneys including Artemio Guerra and Marcela Jimenez Rodriguez to serve one of the country's most diverse workforces.

HKM Employment Attorneys LLP began in 2007 when Donald W. Heyrich left a decade of practice at a major corporate firm to launch a practice 'dedicated to the rights of real people, not corporations,' as the firm's own biography states. He was soon joined by co-founders Daniel Kalish (a Harvard and Yale Law graduate who previously served as a King County prosecutor) and Patrick McGuigan. The firm originally did management-side employment defense work for Qwest Communications but transitioned to plaintiff-side work after losing that anchor client — a pivot that, according to firmwide managing partner Daniel Kalish in a 2026 Law.com profile, eventually grew HKM into what is described on its website as 'the largest employee-side law firm in America.' Today HKM maintains approximately 39 offices across the United States, including its New York City office at 39 Broadway in the Financial District and a satellite office in New Paltz, NY (153 Main Street, Suite 201). The firm's New York practice covers the full range of employee-side employment law: discrimination (race, sex, age, disability, religion, national origin, sexual orientation), workplace harassment, wrongful termination, wage and hour violations, retaliation and whistleblower claims, employment contracts, severance negotiations, non-competes, misclassification, and multi-state class actions. The firm has been recognized by Super Lawyers, Best Lawyers ('Best Law Firms' since 2013), Martindale-Hubbell, the National Employment Lawyers Association, the American Bar Association, Lawyer Monthly, and Global Mobility, with Best Lawyers noting seven HKM lawyers recognized across eight practice areas including Labor and Employment Law – Employee, Personal Injury Litigation – Plaintiffs, Commercial Litigation, and Employee Benefits (ERISA) Law. Several New York attorneys are bilingual in English and Spanish, and the office takes cases against employers of all sizes — from Fortune 500 corporations like Kaiser Permanente, Northrop Grumman, and Walt Disney Co. to small businesses and start-ups.
