He also provides workforce compliance counseling, handles employment-related litigation, conducts internal investigations, and performs employment-related due diligence in advance of company transactions. 

Companies in the health care, telecommunications, financial and professional services, retail, and hospitality industries regularly call on Nathaniel to manage all facets of the employment relationship within their workforces. An avid runner, who has raced in over a dozen marathons and has taken up ultra running during the COVID-19 pandemic, Nathaniel helps clients take practical steps that lead to a successful future.

Following law school, Nathaniel was a clerk for the Hon. William G. Bassler of the U.S. District Court for the District of New Jersey (2004 to 2005).


  • Obtained a temporary restraining order in state court and leveraged firm contacts to pursue criminal sanctions through the U.S. Attorney’s Office against a former independent contractor of a global telecommunications company. The contractor, who was separated from the company, engaged in a campaign of sending harassing, threatening, and disparaging emails and text messages to the company. Once Nathaniel initiated litigation, the contractor ceased his harassing conduct, personal safety was restored, and business relationships remained unharmed.
  • Counseled a global fashion company going through rolling furloughs and layoffs due to the effects of the COVID-19 pandemic on compliance with the federal Worker Adjustment and Retraining Notification (WARN) Act, and its state and local equivalents.  As a result, the company has managed its workforce with minimal impact.
  • Led an investigation for a home health and hospice provider in response to a whistleblower retaliation complaint lodged by a hospice nurse. Nathaniel negotiated a favorable settlement and avoided expensive and time-consuming litigation.
  • Helped defeat claims of breach of fiduciary duty, constructive fraud, and negligence brought by former physician-members stemming from the sale of a controlling membership interest to a company that develops and operates ambulatory surgery centers and surgical hospitals nationwide. Nathaniel not only helped defeat the claims but also secured an award of attorneys’ fees and costs. 
  • Evaluated an AI vendor for the employee recruitment, selection, and onboarding functions for a financial institution and for a publishing company. Nathaniel assessed the product offerings, reviewed vendor contracts, identified the appropriate questions to ask the vendors about their AI products, and monitored and tested the products to determine whether those products would raise red flags from a legal perspective.
  • Has counseled employers throughout the pandemic on layoff decisions, questions surrounding paid time off, workplace safety protocols, COVID-19 testing, and whether they can and/or should require their employees to receive a COVID-19 vaccine. Nathaniel has become a go-to thought leader in the firm on COVID-19 vaccination and has advised numerous employers, across industries, regarding their vaccination plans and policies.
  • Represented a large physician practice in an American Health Lawyers Association (AHLA) arbitration in which the doctor-plaintiff alleged claims of gender and pregnancy discrimination, and where the arbitrator found in favor of our client on all counts.
  • Arbitrated claims of religious, race, and national origin discrimination brought by an EMT. Nathaniel convinced the arbitrator to dismiss all claims against our client after a week-long hearing.
  • Obtained the dismissal of all claims by the D.C. Superior Court in a case involving novel issues of the scope of family responsibilities discrimination under the DC Human Rights Ac.
  • Obtained a favorable resolution of a wage-hour collective action brought in the Eastern District of Virginia in which the plaintiff call-center employees alleged off-the-clock claims under the FLSA.
