Calfee, Halter & Griswold

Founded in Cleveland in 1903 by Robert M. Calfee, Calfee, Halter & Griswold has grown from a single Ohio office into a firm with locations in Cleveland, Columbus, Cincinnati, and Indianapolis. The Columbus office opened in 1988, followed by Cincinnati in 2011 and Indianapolis in 2019, tracing a expansion pattern rooted in Ohio before moving into neighboring markets.

The firm's Corporate and Finance attorneys handle a volume of transactions in a given month that some firms see in a year, supported by a bench of 120+ business attorneys. Intellectual property work runs through a group of 40+ IP & IP Litigation attorneys and professionals, while trial attorneys focus on resolving business disputes efficiently. Lawyer-lobbyists round out the practice, working across Ohio on matters that sit at the intersection of law and policy.

Calfee has held membership in Lex Mundi, a network of independent law firms, since 1989, giving it a long-standing connection to counsel outside its home markets. More recently, the firm has achieved Mansfield Certification for three consecutive periods: 2022-2023, 2023-2024, and 2024-2025. Across more than a century of practice since its 1903 founding, the firm has framed its work around providing meaningful legal and business counsel to the clients it serves.
