What Tressler LLP does
Tressler LLP is a privately held, Chicago-headquartered law firm founded in 1986 that provides legal services through seven core practice areas: Insurance Law, Litigation, Appellate, Transportation & Aviation Law, Government Law, Labor & Employment Law, and HOA & Condo Law, with a specialized Professional Liability practice. The firm represents insurance industry clients coast-to-coast in coverage analysis, litigation, underwriting consultation, claims management, and reinsurance matters, and maintains documented capability to litigate in all 50 states. Tressler serves enterprise and government clients across multiple verticals including insurance carriers, aerospace manufacturers, public school districts, municipalities (including the City of Chicago Board of Elections), and condominium/HOA associations.
The firm operates ten offices across six states (Illinois, California, New Jersey, New York, Pennsylvania, and Missouri), with San Francisco and San Diego offices launched in March 2025 marking its first West Coast expansion. Tressler's go-to-market relies on direct client engagement, attorney referrals, thought-leadership content (publications, the Tressler Talks webinar series, YouTube), and speaking engagements at industry conferences including DRI, CLM, AIA, IML, and CAI. The firm has invested in formal marketing leadership through a Chief Marketing Officer (Anna Hanson) and has built brand credibility through four consecutive years of Great Place to Work certification, AM Best Client Recommended status (seven consecutive years), Best Lawyers recognition, and a #14 ranking on SurePoint's Top 200 Mid-Sized Law Firms list (2026).
Tressler's revenue model is professional services billing, primarily hourly by attorney with rates varying by practice area and seniority, and the firm introduced a retainer program in 2026 to offer predictable budgeting for clients. The firm has no disclosed funding, no parent company, and is structured as a Limited Liability Partnership owned by its partners. Headcount is approximately 100+ attorneys, with 36 lateral hires added in 2025 and multiple partner promotions across Insurance, Litigation, and Government practice groups, indicating an aggressive growth posture funded by operating revenue rather than external capital.
