Biography
John Grantham is the founder of Grantham Law Firm PLLC, a Dallas-based law firm focused on business counsel, contract matters, and commercial litigation.
John has practiced law for nearly two decades. He began his career at the Houston office of Akin Gump Strauss Hauer & Feld LLP, where he spent almost ten years in the firm's complex commercial and intellectual property litigation practice. His experience includes motion practice, trial preparation, depositions, and courtroom advocacy in business and technology-related disputes, including bench and jury trials through verdict.
John's litigation background gives clients a practical assessment of how a dispute is likely to unfold, what it may cost, and where there may be leverage to resolve the matter efficiently.
In addition to his litigation experience, John brings a business-counsel perspective shaped by an unusual combination of legal and aviation experience. He holds a law degree, a B.S. in Aeronautical Science, and a commercial pilot certificate. That background informs his current work supporting international legal matters for a major U.S. air carrier, where he handles contracts, commercial issues, regulatory coordination, and legal support across multiple jurisdictions.
Through Grantham Law Firm PLLC, John works with businesses and individuals who need direct access to experienced counsel. The firm handles commercial disputes, contract review and negotiation, outside general counsel support, and business legal matters that require judgment, focus, and practical execution.
