As the Founding Partner of Jeffrey Law Office, LLC, attorney Antonio L. Jeffrey represents victims of employment discrimination, civil rights violations, personal injury matters, wrongful death claims, and workplace and catastrophic injuries. In doing so, Mr. Jeffrey relies on over a decade of experience serving as counsel for Fortune 500 companies, including major automotive manufacturers and multinational; retail companies in defense of products liability and workplace injuries, respectively; hospitals and physicians in medical malpractice claims; and numerous employers and insurance carriers in the defense of workers' compensation matters. He has litigated cases in state and federal courts across the country, including Delaware, Oklahoma, Indiana, Mississippi, and Illinois, to name a few. 

After successfully representing companies for over ten years, Mr. Jeffrey now utilizes that experience to represent individuals injured as a result of civil rights violations, catastrophic personal injury matters, and workplace injuries. He also represents individuals facing criminal charges who have been wrongfully convicted due to constitutional violations.

Clients appreciate Mr. Jeffrey's aggressive approach in handling their claims and admire his unparalleled responsiveness to their legal needs. His experience, knowledge of the law, and strong work ethic yield his ability to make his clients feel at ease as he fights to achieve favorable results. 

It is because of the aforementioned that Mr. Jeffrey has become one of the elite attorneys in his practice areas. The American Bar Association Torts and Insurance Practice Section selected him as one of the 23 emerging attorneys across the country by way of its distinguished Leadership Academy Class of 2013. Mr. Jeffrey also served as Co-Chair of ABA TIPS Workers' Compensation Midwinter Conference in Chicago, IL in March 2014; served on ABA TIPSA Task Force on Leadership Diversity; and as Vice-Chair of several committees.
