Expanded Expertise Provides Additional Services for Clients

Nathan Associates, a premier provider of world-class economic and analytic solutions, is pleased to announce it has recently acquired litigation services and consulting firm Gnarus Advisors LLC. With a combined team of over 200 prominent experts and professionals in dozens of disciplines, Nathan and Gnarus – which will now be known as “a Nathan company” – will now offer corporate, government, and association clients across all sectors an even more comprehensive scope of services from a deeper bench of talent.

“Our two companies align around shared core values and culture, emphasizing excellence, client satisfaction, and collaboration throughout all of our engagements,” said Nathan CEO Sue Chodakewitz. “Nathan’s 70-year history complements Gnarus’ relative youth, and together, we have the agility and stability to provide a greater breadth of offerings, supporting more clients across more industries.”

Gnarus offers analytic and expert services to clients facing complex challenges arising from uncertainty, potential litigation, or disputes. The acquisition adds Gnarus’ deep expertise in environmental advisory and litigation, insurance coverage & claims analysis, and product liability & mass torts to Nathan’s existing portfolio of experts in antitrust, intellectual property and employment. The acquisition diversifies Nathan’s litigation services and builds on its successes in economic analysis, business consulting, advanced analytics, and international development.

The combined litigation practice, helmed by Gnarus’ Founder and Managing Director Stephen Sellick, will maintain a nimble and customized approach that provides for optimal client engagement. Sellick has also joined Nathan’s Board of Directors.

“Gnarus was founded in order to provide clients with exceptional analysis and to create an organization focused on excellence and supporting our experts and staff,” said Sellick. “In sharing these goals, Nathan is an ideal platform for us to continue to address our clients’ most complex challenges.”

“Merging our organizations creates new opportunities for professionals to be a part of a firm that values a culture of superior client service, entrepreneurial spirit, and nimble and thoughtful leadership,” added Chodakewitz. “It is these professionals who will find a welcome home at Nathan, benefitting from our ability to cross-sell a full range of services and superb internal support.”

The combined firm now has corporate offices in greater Washington, DC; Boston, MA; Los Angeles, CA; Palo Alto, CA; Irvine, CA; London, UK; New Delhi, India and Chennai, India.

As a result of this acquisition, Nathan has appointed Bret C. Cohen as Vice President & General Counsel. Any inquiries about this acquisition can be directed to Mr. Cohen at  or via phone at +1 202-670-5098.
