How tiers are assigned

Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.

Barclay Damon sits in Tier 1 — Market leaders — of Sartori's New York Mass Tort & Toxic Tort board as of July 2026, alongside Manning Gross + Massenburg, Marshall Dennehey, Segal McCambridge Singer & Mahoney.

As of July 2026 that is Barclay Damon, Manning Gross + Massenburg, Marshall Dennehey, Segal McCambridge Singer & Mahoney. Within the tier no firm outranks another.

This ranking is compiled independently by Sartori from public sources. Tiers are Sartori’s editorial opinion, expressed without numeric scores; firms are named for identification only, no logos are reproduced, and no firm has paid for or approved its placement.
