About Us

Tom Dewey, Dave Pegno, and Steve Kramarsky founded the boutique law firm Dewey Pegno & Kramarsky in 1998. We have an established record of successfully representing our clients in complex litigation matters, including trials, appeals, and investigations. Each dispute requires a bespoke approach and does not mandate an army of lawyers or a biglaw “playbook.” We provide a team-based, tailored, and flexible process to working with our clients to reach a successful outcome.

Chambers USA says, “Dewey Pegno & Kramarsky is a respected litigation boutique fielding expertise in a broad range of complex commercial disputes, including contractual breaches, shareholder litigation and arbitral enforcement. It is regularly retained by prominent names in the finance, real estate and insurance sectors.”

The New York Times says, “Other successful practices have remained decidedly small. The grandson of Thomas E. Dewey, for example, has his own firm, Dewey Pegno & Kramarsky, a litigation boutique in Manhattan that he started in 1998. Thomas E.L. Dewey’s 14-lawyer shop, which represents large corporate clients... markets itself as a cost-effective alternative to large, expensive firms.”

Dave Pegno Quoted in Law360 on Supreme Court’s Arbitration Decision

Dewey Pegno & Kramarsky founding partner Dave Pegno was quoted in a May 21, 2026 Law360 article examining the U.S. Supreme Court’s unanimous decision in Adrian Jules v. Andre Balazs Properties et al., which held that federal courts retain jurisdiction over enforcement proceedings after sending a dispute to arbitration.

The article, “Jules Decision Provides Arbitration Certainty Post-Badgerow,” explores how the ruling clarifies questions that lingered after the Court’s 2022 decision in Badgerow v. Walters regarding the role of federal courts in arbitration-related litigation.
