Expert guidance on a complex government contract dispute

I retained Matthew Cannon at Greenberg Traurig when my company faced a challenging dispute over a federal government contract. His deep, 28-year experience in government contracts and white-collar defense was immediately evident. He provided a clear, strategic roadmap and his recognition by Best Lawyers in this field gave us great confidence. Matthew was thorough, personally invested, and his analysis of the qui tam implications was particularly insightful. The resolution was favorable and his counsel was invaluable. While his response time could occasionally be slower than expected given his caseload, his expertise more than compensated. I would highly recommend him for sophisticated legal matters.
