Andrew Fleming represents individuals and companies of all sizes in complex commercial litigation. He has extensive experience in contract, employment, real estate, partnership and business disputes. 

A litigator with extensive trial experience, Andrew has obtained through trial verdicts (jury and bench) or settlements over $300 million collectively for clients and has successfully defended claims of a similar scale. Andrew recently won a jury verdict of over seven figures in the Circuit Court of Cook County against a Fortune 500 company for breach of an Original Equipment Manufacturer contract.

Andrew has been recognized repeatedly by peers for his outstanding legal ability and professionalism. He has earned numerous awards and honors, including listing as an Illinois Leading Lawyer annually since 2004, a recognition given only to the top 5% of lawyers in Illinois. Andrew is also an Illinois Super Lawyer® in the area of business litigation.

Andrew’s practice has always been diverse and interesting and often involves high-stakes litigation. One such case involved a dispute over a priceless work of art, a valuable Monet painting (Pommiers en Fleurs) that belongs to the Union League Club of Chicago.  One of the Club’s ex-members claimed that the Union League Club had agreed to sell his client the painting and initiated suit in the Circuit Court of Cook County, Illinois, in an action styled Thompson Fine Art Limited vs. Union League Club of Chicago, Case No. 2021 CH 00502. Andrew successfully obtained judgment on the pleadings in favor of the Club within two months of the case being filed. The plaintiff took the case up on appeal and Andrew successfully defended the judgment.

Another high-stakes matter related to the mass shooting that took place during the July 4, 2022, parade in Highland Park, Illinois. Following the tragic deaths of a couple, a family relative started a GoFundMe account to raise money for their orphaned two-year-old son. The fundraising became the largest fundraiser in the history of GoFundMe and raised over $3 million in a matter of days. Andrew was retained to ensure that these funds would be protected and used only for the support and best interests of the child. Within less than two days of being retained, Andrew had a trust prepared and a petition on file in the Circuit Court of Lake County, Illinois, placing the trust and the proceeds of the GoFundMe account under the direct supervision of the Court. Andrew’s quick and decisive actions ensured that the monies raised will always be used solely for the benefit of the orphaned son.

Andrew has represented a number of manufacturing clients with plants throughout Europe and the United States; has defended major product liability cases involving wrongful death, mass torts and major class actions; and has represented real estate developers, lenders and brokers in every type of dispute in the real estate industry. He is experienced in business torts, litigation involving financial institutions and partnership law, and has represented numerous energy suppliers in contract disputes. Andrew’s diverse practice has brought him to litigate cases in California, Louisiana, Michigan, Texas and Virginia, among other places.

A lawyer with a true international background, Andrew was also asked to appear in federal court in Michigan to testify as an expert on U.K. defamation law on behalf of a multilevel marketing company in a dispute with a U.K.-based manufacturer of vacuum cleaners.

Andrew is a member of the Order of Malta, a humanitarian organization founded in 1113 as a lay religious order of the Roman Catholic Church. The Order is dedicated to the care of the sick and the poor. Andrew volunteers every month at a soup kitchen operated by the Order at a church in Chicago’s Uptown area. He has also devoted significant time to Mission Outreach, a warehouse facility near Midway Airport that sorts and packs medical supplies donated by local hospitals and distributes them worldwide to those in need. Chicago-area members of the Order also assist in home-rebuilding projects every Spring.


Andrew was previously a partner at Novack and Macey in Chicago, and joined Armstrong Teasdale in 2023.
