Ryan Leonard has extensive experience litigating cases in federal and state courts, and specializes in solving complex business problems for his clients. Ryan practices primarily in the areas of business law and litigation, insurance law, receivership law, and oil and gas litigation. He maintains the highest Martindale-Hubbell Preeminent Attorney Recognition (“AV”) rating for skill and ethics for attorneys based on professional peer reviews, and has been selected annually since 2016 as a top-rated “Super Lawyer” for business litigation.
Prior to entering private practice, Ryan served as a state prosecutor in the District Attorney’s office in Canadian County, Oklahoma. Ryan also served for four years (1994-98) as a Legislative Assistant to former U.S. Senator Don Nickles in Washington, D.C., in which capacity he served as the Senator’s chief legislative aide on issues involving the federal judiciary, Indian Affairs, transportation, agriculture and natural resources.
Ryan is very active in the local community, currently serving as Chairman of the Board of Directors of Mercy Hospital- Oklahoma City. Ryan co-founded and is a past president of the Downtown Club of Oklahoma City, and previously served on the Board of Trustees of the Oklahoma City National Memorial, the Board of Directors of the Central Oklahoma Red Cross, the Central Oklahoma YMCA and KIPP Charter School, the Executive Committee of the Board of Directors for the Oklahoma Academy of State Goals, the Legal Ethics Committee of the Oklahoma Bar Association and was a member of Leadership Oklahoma Class XIX. Ryan has also volunteered his time pro bono for Oklahoma Lawyers for Children, serving children at risk in the foster care system. At a younger age, Ryan earned the rank of Eagle Scout.
In 2008, Ryan was appointed by the Governor as a Commissioner representing the State of Oklahoma on the national Uniform Law Commission, and was reappointed in 2014 and 2018. In 2015, Ryan was appointed by the President of the national organization to the Executive Committee, and as chair of the national Legislative Council. Ryan has served on numerous committees within the organization, including drafting committees implementing the Hague Convention on Choice of Court Agreements (facilitating international contracts) and drafting a Model Tribal Probate Code. Ryan co-chairs the Committee on Attendance, and serves on the Committees on Scope and Program and State and Federal Relations.
Through his law practice, Ryan is also regularly appointed by Courts as a “Receiver” over troubled businesses, tasked with either managing, rehabilitating, or liquidating the business. In 2018, at the request of the Oklahoma Insurance Commissioner, the Oklahoma County District Court appointed Ryan as “Interim CEO” of Union Mutual Insurance Company, an Oklahoma-domiciled insurance company, that was successfully rehabilitated and emerged from receivership.
Ryan earned his law degree from the University of Oklahoma, and graduated magna cum laude from Boston College. Ryan also attended the L’Institut d’Etudes Politiques in Strasbourg, France. In his spare time, he enjoys coaching his children's activities, reading history, travel and archaeology. He is the co-author of “Opala: In Faithful Service to the Law,” a biography on former Oklahoma Supreme Court Justice Marian Opala, as well as "Principles and Perseverance: The Life of Don Nickles."
Ryan is admitted to practice before the Oklahoma Supreme Court and all Oklahoma state courts, the federal courts of the Western and Northern Districts of Oklahoma, the 10th Circuit Court of Appeals and the United States Tax Court.
