Aggressive Houston Criminal Defense and DWI Lawyer

About Us

If you have been charged with driving while intoxicated (DWI), driving under the influence (DUI), or any other criminal offense, it is critical to obtain experienced legal representation to ensure the most positive outcome for your case. Matthew Gallagher is a licensed Attorney at Law in the state of Texas and has experience in defending DWI, DUI, and other criminal offenses in Houston.

During the stress of an arrest or a police interrogation, many accused individuals make mistakes and say things that prove devastating to their later defense. The accused individual has the right to legal counsel and the right to remain silent; giving up these rights can help the government secure a criminal conviction against the accused that can impair their ability to find future employment among many other things.  The consequences of a criminal conviction can have devastating effects on their future.

Contacting a qualified Houston criminal defense attorney before making any statements to the police or agreeing to any type of meeting can prevent the accused from damaging their own case. As a skillful and knowledgeable Houston criminal defense attorney, Matthew Gallagher has been successful in getting many cases dismissed outright. In other cases, he has been able to come to very favorable plea agreements with prosecuting attorneys to allow his clients to avoid felony and/or misdemeanor convictions that could seriously affect their future.
