About

Founded in 1945, Quinn Johnston provides comprehensive legal services to its clients ranging from private individuals to large business entities.  With more than twenty-five lawyers in offices in Peoria and Springfield, the firm litigates cases in most all counties within Illinois and serves business clientele throughout the downstate Illinois area. The firm’s practice broadly covers the areas of business, civil litigation and healthcare.

Well-Deserved Recognition

Quinn Johnston has received outside recognition of its commitment to excellence in service. In 2013, Fortune Magazine listed the firm as one of the Top Ranked Law Firms, and in 2014, Corporate Counsel Magazine placed the firm on its list of Top Ranked Law Firms in the United States. Martindale has awarded the firm with an AV rating (Martindale’s highest ranking for both ability and legal ethics) for years, and thirteen of the partners within the firm have their own individual AV ratings. The firm annually earns recognition for several of its attorneys from the Illinois Leading Lawyers Network and Chicago Magazine’s SuperLawyers.

Community Involvement

Quinn Johnston is proud of its history of community involvement.  The lawyers here recognize their obligation to promote the local community though pro bono work for those who cannot afford legal services. The firm’s lawyers hold leadership positions in local civic, charitable and political organizations and bar associations.  Quinn Johnston was pleased to be one of the original signatories to the Peoria County Bar Association’s Diversity Pledge. The firm annually hosts a fund-raising event for a local charity, most recently for central Illinois’ Meals-On-Wheels program.
