Nathan Warecki

Nathan Warecki is an associate in Nixon Peabody’s Complex Commercial Disputes group, and teams with attorneys and other legal professionals on a wide variety of matters, including commercial litigation, class actions, non-competes and trade secrets, business disputes, and immigration.

What do you focus on?

My role at Nixon Peabody is to help our clients navigate the many legal challenges associated with an ever-changing world. I concentrate on the following areas:

Commercial Litigation and Class Actions

I represent businesses, manufacturers, banks, utilities, employers and individuals in complex state and federal litigation relating to contracts, leases, franchise agreements, trade secrets, unfair and deceptive trade practices, class actions, employment agreements, products liability, and other business disputes. My experience includes representing medical device and other product manufacturers with respect to workplace accidents or botched medical procedures, international franchisors in lawsuits involving franchisees, master franchisees, and consumer class actions, regional and national banks in multimillion dollar loan workouts, public utilities with respect to business disputes with competitors, and medical providers pursuing former employees and hospital-clients for contractual breaches. As a member of both the Class Actions and Aggregate litigation and Non-Compete & Trade Secrets teams, I work with colleagues across practice areas and on behalf of clients throughout the United States.


I have represented several New Hampshire-based colleges where I helped them to sponsor international faculty and staff for employment visas and worked with the international student office to help the institution with Student and Exchange Visitor Information System (SEVIS) and other international student matters. For a private secondary school, I was part of a team engaged to litigate breach of contract claims lodged by a student placed on leave due to misconduct.

Alternative Dispute Resolution

Arbitration, mediation and negotiation are useful tools for the resolution of disputes. In many cases, alternative dispute resolution can settle disputes without the cost and publicity of protracted litigation. I assist clients in identifying opportunities for non-judicial settlement and help clients understand when litigation is the more appropriate tool for resolution.


The rules and regulations governing immigration are onerous. Foreign nationals face a multitude of options and barriers to their bids to successfully live, work and study in the United States. I assist businesses, universities, hospitals, investors, entrepreneurs and highly skilled workers in identifying temporary and permanent visas to accomplish their business, professional and personal goals. I have also led or participated in a number of high-profile civil rights lawsuits filed on behalf of immigrants aggrieved by immigration enforcement actions. This includes a class action lawsuit filed on behalf of children separated from their parents by United States government officials after apprehension, a group of Indonesia Christians and long-time residents of New Hampshire seeking to stay their removal on account of religious persecution, and civil immigration detainees detained at the Strafford County House of Corrections in light of the COVID-19 pandemic.

Professional and Community Interaction

I currently serve as a director for Intown Concord, Inc. in Concord, New Hampshire. I have also served as a panelist for national conferences relating to business immigration and am a contributor to professional and trade publications.

What do you see on the horizon?

I am following the role of law and lawyers in the “innovation economy”—particularly how existing legal concepts are used to solve 21st century issues and disputes.
