R. Michael Vang

Attorney

Mr. Vang graduated from Kelly Walsh High School in Casper Wyoming, where he won the Wyoming High School Cross Examination Debate Championship at the University of Wyoming in 1982. Mr. Vang received a debate scholarship to attend the University of Wyoming, where he obtained his undergraduate and law degrees. Mr. Vang was one of only two college students in the entire country named to the United States Collegiate Debate team that traveled to Great Britain to compete in the spring of 1991. For the last twenty (20) – years, Mr. Vang has taught other attorney’s all over the United States how to defend criminal cases.

Although Mr. Vang’s parents were killed by a drunk driver right after Mr. Vang graduated from high school, one of Mr. Vang’s first cases was a DUI charge. Mr. Vang explained his history and how he was not comfortable representing the person accused of a DUI charge until Mr. Vang reviewed the discovery in the case. After reviewing the discovery created to try to prove guilt for the DUI charge, Mr. Vang told the client about all the different defenses that existed and that Mr. Vang was willing to assert on the client’s behalf. The client hired Mr. Vang and Mr. Vang obtained his first acquittal and has been representing people accused of criminal charges for over twenty-eight (28) – years ever since then.

On June 13, 2015, Mr. Vang became the only attorney in Wyoming to receive “The American Chemical Society (ACS) Forensic Lawyer-Scientist Designation as recognized by the Chemistry and the Law Division of the ACS.” Mr. Vang has successfully argued that the chemical testing measurements in many of his DUI and drug cases are not accurate or reliable and cannot prove guilt beyond a reasonable doubt.

On July 14, 2022, Mr. Vang was awarded the National College of DUI Defense’s “Trial Advocacy Award,” which is given to the NCDD member who has most personified the mission of the National College through an aggressive, creative, and ethical trial practice that is dedicated to defending those accused of impaired driving. This individual has set themselves apart in their local community as a premier DUI defense trial attorney and has litigated a number of DUI-related cases to verdict.
