No longer actively involved in litigation, Tom Blumenthal concentrates his practice in Dispute Resolution, both online and in person. Dispute Resolution through Mediation, Arbitration, or Early Neutral Evaluation is no longer the exception, and online Dispute Resolution is the most practical way to engage in Dispute Resolution in a convenient cost-effective manner for all parties See our Dispute Resolution practice area page, here.

Tom still serves as a mentor and resource for the Firm’s litigation attorneys and an advisor on ethics compliance. He participates in the Firm’s appellate work in both drafting, review and strategic assessment.

Having advocated for clients in courtrooms, appellate courts, mediations, and arbitrations for over 40 years, in St. Louis and in many other parts of the country, Tom tried and won complex jury and court-tried cases and briefed and argued cases to appellate courts including the Missouri Supreme Court and the United States Supreme Court. He has mediated and served as an arbitrator on business, commercial, intellectual property, real estate, construction, and employment cases since 1995.

Tom taught arbitration at the Washington University School of Law from 2006 through 2010, having developed the syllabus and curriculum, and is on national and international arbitration and mediation panels with the American Arbitration Association and other provider organizations.

Tom believes in the responsibility of the Bar to help those in need. He volunteers as a facilitator to the Missouri Bar Dispute Resolution Program, working on disputes between attorneys and their clients. He has represented the poor, the marginalized, and the exploited of society in their quest for justice and fair treatment under the Constitution, first as a Reginald Heber Smith Community Lawyer Fellow, then as a Legal Aid attorney, and for years as a co-operating attorney for the American Civil Liberties Union.
