Professional Experience:

Robert B. Sullivan is the CEO and Manager of Sullivan Mediation+Arbitration, LLC in Overland Park, KS. As an attorney, he has engaged in a number of practice areas, including tax controversies, estate planning and probate disputes, mergers and acquisitions, corporate governance, employment law (including wrongful termination, retaliation, gender pay and promotion discriminations, etc.), administrative law, and insurance industry disputes, including insurance policy and coverage disputes, producer/broker contract disputes, insurance transactional issues, misrepresentations of representations and warranties in stock purchase agreements, class actions and reinsurance intermediary contract disputes.

Sullivan is a Kansas Supreme Court approved mediator. He also has been approved for listing as a mediator pursuant to Rule 17 of the Missouri Supreme Court for the Missouri state circuit courts, by the U.S. District Court for the Western District of Missouri and the Kansas U.S. District Court. He was, prior to his retirement, an equity shareholder in the law firm of Polsinelli PC for over 27 years.

Sullivan received his Bachelor of Science in Business Administration from Pittsburg State University, where he was a distinguished Military Graduate, and commissioned as a Second Lieutenant as a Regular Army officer. Sullivan graduated from the University of Kansas School of Law and was awarded the Juris Doctorate Degree. While in law school, Sullivan was the President of the Moot Court Council and, upon graduation, was awarded the Samuel Mellinger Scholarship, Leadership and Service Award given to the graduate who most distinguished himself or herself in the combined areas of scholarship, leadership and service. He also received his Master of Laws Degree (LL.M.) from Emory University Law School in Atlanta, Georgia. Sullivan served four years as a Captain in the U. S. Army Judge Advocate General Corps, engaging in general and special court martial proceedings, prosecuting and defending persons charged with violations of the Uniform Military Justice Act of 1968 (including acting as an assistant to the Judge Advocate General for Fort McPherson, Georgia in the Mia Lai trial of Captain Ernest Medina).

After his service in the military, Sullivan returned to Kansas City to engage in the private practice of law. He recently retired as an equity shareholder from the Polsinelli law firm after 27 years of practice there. While at Polsinelli, Sullivan formed and chaired the Insurance Industry and Regulatory Practice Group engaging in the representation, for and against, insurance agents, third party administrators, insurance companies, reinsurance companies, captive program managers and captive insurance companies, registered investment advisors, insurance pools, and self-insured entities.

Sullivan is dedicated to serving as a Mediator/Arbitrator/Neutral for persons and entities engaged in civil disputes as a viable alternative to the expensive and time consuming process of litigating disputes in the state and federal judicial system, where crowded trial dockets, pre-trial discovery (interrogatories, request for admissions, production of documents and depositions), motions, hearings, trials, and appeals, can consume thousands of dollars in costs and attorney fees and take months, if not years, before any judicial resolution of a dispute is achieved.
