Drennan possesses twenty (20) years of the knowledge and skills needed to deliver the caliber of results that our clients look for when they hire a defense attorney. DUI and other criminal matters often hinge on highly technical aspects of the circumstances and/or the law.
A conviction on charges of driving under the influence of alcohol, possessing illegal drugs or driving recklessly is always a difficult, disturbing life event. Even traffic tickets may seem relatively minor, but they can lead to increased insurance rates and pose a threat to your driving privileges. Any misdemeanor or felony criminal record can potentially affect many areas of life, including:
- Career
- Family
- Finances
- Housing options
- Freedom to own firearms
- Freedom to pursue many personal goals that may be out of reach permanently as a result of a criminal record
At Drennan Law Firm, every client receives respect from the very first consultation through the conclusion of a case. Preparing to address your legal matter effectively and in your best interests is the heart of what we do at Drennan Law Firm.
