Attorney Profile

Sonja R. Porter is the owner of Sonja R. Porter, Attorney at Law, PLLC. Located in Oklahoma City, she focuses her practice exclusively on criminal defense law, in particular providing representation to clients throughout the greater metropolitan area who have been charged by the state with driving under the influence of alcohol or drugs. Although most DUI cases are treated as misdemeanor charges, Oklahoma law provides that driving under the influence can be a felony if the defendant had a prior conviction for that offense within a specified period of time. While felony DUI charges can result in prison time, Ms. Porter has a strong track record in obtaining acquittals as well as negotiating favorable plea agreements in these types of cases. She also helps clients have their criminal records expunged, which can mean that their criminal records do not appear when their background is being checked for potential employment.

Ms. Porter has lectured extensively on topics related to her practice before the Oklahoma Bar Association and other groups. Some of the areas that she has covered have included advanced strategies in DUI defense, cross-examination on breath tests, and expungement updates. Ms. Porter's excellent track record and high degree of ethics have earned her the respect of her fellow professionals, as evidenced by her receipt of a review 10.0 "Superb" peer rating through Avvo. She is admitted to practice in Oklahoma and before the Supreme Court of the United States.

Ms. Porter pursued her legal studies at Oklahoma City University School of Law and was awarded her Juris Doctor in 1999. She served nearly 12 years as an assistant district attorney before entering private practice. Ms. Porter's professional memberships include the Oklahoma Criminal Defense Lawyers Association and The National College for DUI Defense, Inc.
