Firm Information
Overview
We at Mastantuno Law Firm, LLC, deliver strategic, trial-tested advocacy for clients in Charleston, South Carolina. Our practice focuses exclusively on criminal defense, DUI/DUAC defense and personal injury litigation, ensuring every case receives the depth of attention and skill it merits. When life-changing charges or significant injuries threaten your future, we stand ready to protect your rights and pursue the best possible outcome.
Our criminal defense team defends individuals against a broad spectrum of offenses, including drug possession, assault and battery, weapons violations, theft crimes and probation violations. We leverage years of courtroom experience to challenge evidence, negotiate favorable resolutions and, when necessary, take your case to trial. Recognizing the severe consequences of a conviction, from incarceration to a permanent record, we commit to personalized strategies tailored to each client’s unique circumstances.
In DUI and DUAC matters, timing is critical. Driver’s license suspensions and court deadlines advance rapidly, and a swift, aggressive response can make all the difference. Our attorneys scrutinize arrest procedures, breathalyzer accuracy and field sobriety protocols to identify weaknesses in the state’s case and defend your freedom.
For victims of negligence, our personal injury practice provides compassionate representation after car and motorcycle collisions, slip-and-fall mishaps, wrongful death and other serious accidents. We shoulder the legal burden so clients can focus on recovery, pursuing the best possible compensation for medical expenses, lost wages, pain and suffering, and future care needs.
J. Allen Mastantuno, a Charleston native and graduate of the College of Charleston (B.A., 2003) and the University of South Carolina School of Law (J.D., 2007), leads our firm alongside a dedicated support staff and network of investigators and forensic professionals. We offer virtual consultations, flexible payment options and unwavering commitment. Contact us today for a confidential case evaluation, and let Mastantuno Law Firm, LLC, advocate passionately on your behalf. Partner with us to secure dedicated legal guidance tailored to your needs.
