Nathaniel Cullerton, a partner at the elite New York firm Wachtell, Lipton, Rosen & Katz, has dominated recent headlines after a viral video showed him kissing a younger colleague in Central Park. Amid the professional fallout—including reports of him being placed on leave and a potential move to Gibson Dunn falling through—attention has turned to his wife. Moira Penza is no ordinary spouse. She is a highly respected trial lawyer in her own right, with a career that includes taking down one of the most notorious cult leaders in recent memory.
Here’s a clear look at who she is, their life together, and the context surrounding the current attention.

Who Is Moira Penza?
Moira Penza (sometimes referred to as Moira Kim Penza) is a partner at Wilkinson Stekloff, a high-stakes trial boutique. Before private practice, she served as an Assistant United States Attorney in the Eastern District of New York. There she led the groundbreaking prosecution of Keith Raniere, founder of the NXIVM organization. Raniere was convicted on charges including racketeering and sex trafficking and later sentenced to 120 years in prison. Penza’s work on the case earned her national recognition and appearances related to HBO’s documentary series The Vow.
Nathaniel Cullerton Wife: She graduated from Binghamton University and earned her law degree from Cornell Law School. Her early career included time at Paul, Weiss before joining the U.S. Attorney’s Office. In private practice she has handled complex antitrust, commercial, and high-value litigation, including matters involving Altria and other major clients. Colleagues and legal publications have described her as a sharp strategist who can “go for the jugular when necessary.”
Their Marriage and Shared Life
Cullerton and Penza married in February 2016. Public reports indicate they have built a life that reflects their professional success. The couple shares a $2.3 million Upper East Side co-op near Central Park and a second home in Wilton, Connecticut, where Cullerton has family roots. Some accounts mention they have at least one child, though they keep personal details largely private.
Both partners operate at the highest levels of New York’s legal world—Cullerton at Wachtell and Penza at Wilkinson Stekloff. Until recently, they presented as a classic dual-power-couple success story in elite legal circles.
The Recent Controversy Involving Nathaniel Cullerton
In late July 2026, a TikTok video filmed by comedian Jay Guapo captured Cullerton, then 45, and 29-year-old Wachtell associate Kelsey Borenzweig kissing on a Central Park bench. The clip amassed millions of views. Reports from the Financial Times, New York Post, and Daily Mail indicated Cullerton was placed on leave at Wachtell. A planned move to Gibson Dunn with other partners was reportedly called off. Borenzweig’s status at the firm remained less clear in early coverage.
Penza has not publicly commented. As of early August 2026, no formal statements from either spouse have addressed the personal implications of the incident.

Moira Penza’s Standout Career Achievements
Beyond the NXIVM case, Penza has built a strong record in private practice:
- Served as trial counsel in major antitrust and commercial disputes
- Recognized by Crain’s New York Business, Law360, Bloomberg Law’s 40 Under 40, and Lawdragon
- Handled complex matters for large corporate clients while maintaining a reputation for precise, aggressive advocacy
- Transitioned successfully from high-profile public service to elite private-firm trial work
Her trajectory shows a lawyer who thrives under pressure and has consistently operated at a high level in both government and private practice.
Conclusion
Moira Penza is far more than “Nathaniel Cullerton’s wife.” She is an accomplished litigator whose work on the NXIVM prosecution alone secured her a lasting place in legal history. The recent Central Park video has thrust their private life into public view at a difficult moment for her husband. As of this update, she has chosen silence. In a profession that prizes discretion, that restraint may prove as telling as any statement. For now, the focus remains on the facts: a high-achieving legal couple whose carefully built world has been disrupted by a single viral moment.
