About me

Steve completed both his undergraduate and graduate education in his home state of South Carolina, graduating from the University of South Carolina School of Law in 1992. While at the USC School of Law, Steve was inducted into the academic honor society of the "Order of the Wig and Robe" for superior academic achievement.

After graduating from law school, Steve became a state prosecutor. His primary case load consisted of prosecuting DUI, felony DUI, reckless homicide, and vehicular offenses, as well as other drug and alcohol related charges. This experience not only gave Steve the opportunity to develop and enhance his court room skills in the trial of driving related offenses, it also gave him a valuable "insider's knowledge" of how the prosecution approaches these cases. 

In 1995, Steve opened his own practice as a criminal defense attorney, with a special focus on defending clients accused of DUI and other driving offenses. 

Since then, Steve has developed a reputation as a knowledgeable, skilled, and aggressive DUI lawyer. He is very familiar with the nuances of the South Carolina DUI/Implied Consent laws, which can be quite complex. 

Steve has been a guest lecturer for magistrates, judges, law enforcement officers, prosecutors, law school students, and business associations in the area of DUI law. Steve has also appeared numerous times on television, radio, and newspapers regarding DUI topics from the defense perspective. 

Steve currently represents clients in over 25 courts in Upstate South Carolina. These courts include Greenville, Anderson, Spartanburg, Pickens and Laurens counties; as well as the city/municipal courts of Greenville, Anderson, Spartanburg, Simpsonville, Greer, Fountain Inn, Easley, Clemson, Central, and Laurens.
