What McCullough P.C. does
McCullough P.C. is a Chicago-based law firm operating a national insurance coverage, litigation, and claims management practice from a single office at 205 North Michigan Avenue. The firm was formed in August 2022 by attorneys Sam Rainey and Bart Rinn as a successor entity to McCullough, Campbell & Lane LLP, which was itself formed in 1987. McCullough P.C. represents domestic and foreign insurers and reinsurers — including London market insurers at Lloyd's — across eleven distinct practice areas: Accountants and Auditors Professional Liability; Actuary and Third Party Benefits Administration Liability; Architects and Engineers Professional Liability; Attorneys Professional Liability; Cyber Risks and Privacy Liability; Directors and Officers Liability; Healthcare Regulatory and Medical Professional Liability; Insurance Brokers Professional Liability; Insurance Coverage Litigation; Life Sciences; and Technology and Media Liability.
The firm's core product is specialized legal services delivered as monitoring counsel, coverage counsel, and coverage litigation, with engagements frequently structured as long-term, multi-year arrangements. The practice is augmented by a proprietary claims-handling program and companion intranet application architected by Managing Shareholder Bart Rinn. This trade-secret-protected system provides insurer clients access to current claims information and statistical reporting and outputs claim data in formats that interface with insurer computer systems; it underpins monitoring engagements across multiple professional liability accounts, including architects and engineers programs where reserves are managed in the multiple billions of dollars.
McCullough P.C. operates as a private professional corporation with no parent company, subsidiaries, or external investors. Revenue is generated exclusively through professional legal services fees on a quote-based, bespoke engagement model with no publicly disclosed pricing. The client base is anchored by long-tenured relationships — including more than 30 years of continuous representation of one of the world's largest insurance brokers — and includes insurers of major U.S. law firms, the largest international accounting firms, healthcare regulatory liability policyholders, and large engineering firms. The firm employs 14 attorneys and serves a global insurer client base through its single Chicago location.
