Brunswick Group, Ripp Media, Sard Verbinnen & Co. and Trident DMG all placed in Band 1, the top tier of Chambers’ latest rankings of PR firms involved in litigation support.

London-based Chambers evaluates the firms in its listings by such criteria as technical legal ability, client service, diligence, commercial vision, business understanding and value for money. It also ranks individual practitioners by the same criteria.

Ripp was singled out for the active role taken by senior staff in client relationships. “The person on the other end of the line will be the one to take the next step themselves,” one commenter said. “They're a really strong team in that regard, they all have that seniority.”

Along with Ripp, Brunswick and Sard Verbinnen appeared in Band 1 last year as well.

Washington, DC-based Trident DMG moved up from Band 2, the second-highest category. The firm, which prepared Michael Cohen for his testimony before the US House Committee and managed the publicity around that testimony, was cited for being “innovative, insightful and relentless.”

Finsbury, FTI Consulting, PRCG Haggerty and Sitrick and Company are this year’s Band 2 firms. Band 3 consists of Edelman, Infinite Global and Kekst CNC; Band 4 includes KARV Communications, Levick, Reevemark and The Levinson Group; and the firms in Band 5 are Abernathy MacGregor Group, Hellerman Communications, Joele Frank Wilkinson Brimmer Katcher, Poston Communications and Rubinstein.

The Chambers website stresses that “being ranked in any band is a significant achievement.”

The individual advisors who received Band 1 rankings were Ripp Media’s Allan Ripp, Brunswick Group’s Ellen Moskowitz and Trident DMG’ Lanny Davis.
