A DUI Defense Attorney with a Wealth of Experience

Attorney Jim Medley is one of the only DWI attorneys in the country with a Master of Science degree in Forensic Toxicology. Almost every Harris county DWI arrest involves the work of chemists who work for the police. Whether your case involves a blood draw or a breath test, there is particular forensic documentation that must be properly maintained in order for a measurement of alcohol concentration to be admissible in court. Only specifically trained Houston DWI defense lawyers have the proper background in science to question the admissibility of blood or breath alcohol level lab results. Attorney Medley is uniquely qualified in this area of DWI defense.

Attorney Medley knows that every police arrest does not involve mistakes by officers or insufficient evidence. Some Harris county criminal cases involve strong evidence that was obtained lawfully. These cases require careful counseling and skillful negotiation skills that only experienced Houston DWI defense lawyers have. In these situations, Jim relies on his over 20 years of experience talking to judges and prosecutors about creative ways charges can be resolved with dismissal or reduction even when the evidence is unquestionable.
