Blair E. Kaminsky



A partner and member of Holwell Shuster & Goldberg’s management committee, Blair Kaminsky represents both individuals and corporations in complex commercial litigation and investigatory matters frequently touching on large-scale transactions and the financial services industry. Crain’s New York Business has recognized her as a Notable Woman in Law, and her clients have described her to Benchmark Litigation as a “fantastic litigator who provides thoughtful, spot-on advice,” and “manages enormous cases with creativity and enthusiasm.” Chambers USA honored her as an “up and coming” lawyer for general commercial litigation in New York in its 2022 and 2023 guides, with clients and peers stating she “does a remarkable job in court” and “sees the forest, the trees, and the underbrush.”

Blair is widely respected for her leadership and advocacy in litigation with wide-ranging social and economic impacts, including high-stakes RMBS putback litigation that first arose in the Great Recession. In another wave of commercial litigation with potential exposure in the billions, Blair represents Visa in multi-district class action antitrust litigation filed on behalf of merchants, as well as in opt-out cases brought by the world’s largest retailers, relating to network rules at the heart of the Visa system. In addition, Blair represents Chubb in insurance coverage disputes related to the opioid crisis, and advises on shareholder class actions, white-collar defense matters, bankruptcy litigation, and employment disputes. In these and other similarly complex cases, Blair works tirelessly to develop relationships with co-counsel and opposing counsel, and looks across cases to leverage synergies and ensure consistency across portfolios of multiple cases in various fora. As peers and clients shared with Chambers, Blair has the “ability to find consensus, manage the intricacies of multiple litigations and navigate the thorny relationships involved,” and to “channel her photographic recall of the facts, law and procedural history of a case and use it to direct the overall litigation strategy and goals.”

An active participant in HSG’s pro bono practice, Blair spearheaded the development of the firm’s partnership with Her Justice, an organization providing legal services to women living in poverty in New York City. Blair’s own pro bono matters include her representation of a college freshman survivor of sexual assault with respect to her civil rights and potential remedies under university policies and Title IX.

In addition to her litigation work and service on HSG’s management committee, Blair plays a leadership role in HSG’s marketing and recruiting efforts, which have brought diverse and talented lawyers to the firm. Blair was instrumental in the formation of the firm’s Diversity & Inclusion Committee and the development of HSG’s formal mentoring program.

Blair is a member of The American Lawyer’s first-ever Young Lawyer Editorial Board, and speaks frequently on topics ranging from ethical obligations in e-discovery to fostering diversity and inclusion at law firms. Blair has received many honors for her work, including being selected as one of only 10 honorees for the New York Business Journal’s 2022 Women of Influence award. She is the recipient of Euromoney Legal Media Group’s 2019 Rising Star Award for Best in Litigation: General Commercial and was named to Profiles in Diversity Journal’s 2016 Women Worth Watching list.

Prior to joining HSG, Blair was a litigation associate at Wachtell, Lipton, Rosen & Katz, where she represented JPMorgan in the Lehman Brothers bankruptcy litigation and NYSE Euronext in litigation over a contemplated $10 billion merger that would have created the world’s largest stock market. After graduating magna cum laude from Harvard Law School, where she was supervising editor of the Harvard Law Review, she clerked for the Hon. Judith Rogers of the U.S. Court of Appeals for the D.C. Circuit.
