Hamilton Weber

What Hamilton Weber does

Hamilton Weber LLC is a full-service regional law firm headquartered in Saint Charles, Missouri, founded in 1999 (originally as Hazelwood & Weber, LLC) by five attorneys formerly of two of Missouri's largest law firms. The firm operates from a single office at 200 N 3rd Street, serving the metropolitan St. Louis area, the State of Missouri, and southwestern Illinois with a professional staff of approximately 21 (17 attorneys, including 9 partners and 8 associates, plus 4 paralegals/law clerks/administrative staff).

The firm's practice is organized around four primary service lines: State and Local Municipal Law (city attorney representation, special districts, zoning and land use), Civil Litigation (commercial, medical malpractice defense, construction, class action, civil rights, labor and employment, workers' compensation, personal injury, real estate, and federal court), Real Estate Law (commercial transactions, condemnation, HOA representation, land use development), and Corporate Law (business formation, commercial public finance, estate planning/probate, M&A advisory). Mediation services are offered as an alternative dispute resolution channel through founding partner David Hamilton. The firm holds Tier 1 Best Law Firms rankings (U.S. News & World Report) in Commercial Litigation, Medical Malpractice Law-Defendants, and Municipal Law for 2026.

The business model is a traditional professional services model built on hourly billing for litigation and transactional work, supplemented by ongoing municipal retainer relationships. The client base spans local governments (six municipalities plus Warren County), healthcare providers (Mercy Hospital), gaming and hospitality companies (Caesars Entertainment, Boyd Gaming, Ameristar Casino St. Charles), manufacturers (VSM Abrasives, Starcke Abrasives USA, Newco Enterprises), and individuals requiring estate planning services. The firm is privately held by its partners with no external investors, no parent company, and no institutional ownership. Client acquisition is relationship-driven, relying on civic participation, bar association involvement, educational presentations, and referral networks rather than a sales-led growth motion.
