Bio overview

One of Oklahoma’s most prominent corporate attorneys, Martin Stringer has a wealth of legal experience and expertise as a negotiator in the fields of business, financial institutions and governmental relations. His legal practice is concentrated in the area of business law, with emphasis on negotiating and structuring business combinations, including acquisitions, mergers and other private and public securities transactions. He is widely regarded for his strategic planning expertise in complex business litigation matters and his experience in counseling corporate and financial institutions on financial, state and federal regulatory and legislative matters, and in particular, corporate governance under the provisions of Sarbanes-Oxley.

Martin is also a key member of the firm’s Sports Industry Group.  In 2008, he represented the owners of the Seattle SuperSonics in settlement negotiations with the City of Seattle, Washington, that resulted in the relocation of the NBA team — subsequently renamed the Oklahoma City Thunder — to Oklahoma City prior to the start of the 2008–2009 basketball season. In addition to representing the Thunder ownership group in ongoing matters, he also represents the Dallas Wings WNBA team and a number of individual professional athletes as part of his sports practice.

His achievements have earned him repeated inclusion in some of the nation’s most prominent legal guides, including The Best Lawyers in America (corporate law; corporate governance law; mergers and acquisitions law), Oklahoma Super Lawyers, and the Chambers USA Guide to America’s Leading Lawyers for Business. He has been lauded by interviewees of Chambers as client-oriented, creative and candid, having what it takes to close a deal, and admired by peers as one of the best corporate merger and acquisition lawyers in America for his knowledge of financing.

Prior to joining McAfee & Taft in 2005, Martin served as director and president of McKinney & Stringer, a corporate law firm he co-founded in 1971. Throughout his career, he has also served as a trial attorney in the county district attorney’s office, worked as a campaign aide to a former U.S. senator, and mediated for the System Board of Adjustment of the National Labor Relations Board and the National Association of Securities Dealers.

Martin is a frequent lecturer at bar association seminars, law schools, and business group conferences.
