In his years with the Sheriff’s Office, John spent a total of 14 years working death investigations. This extensive experience dealing with the most serious of cases has given John an eye for detail that few Houston criminal lawyers have.

This unit was responsible for investigating serious and fatal accidents as well as commercial vehicle enforcement. John’s training as an accident investigator and experience as an intoxilyzer operator, gives John a unique perspective when dealing with cases that involve alcohol, an accident, or both. John understands the special rules for CDL holders and how being charged with a crime can significantly impact a person’s ability to hold that license.

In criminal cases, John is well aware that the State of Texas holds most of the cards. Even when inexperience, inadequate training, failure to follow proper procedures, and “tunnel vision” result in flawed police investigations, the State has the power to bring about charges and even convictions However, John’s background and experience gives him the ability as a Houston criminal lawyer to pick apart all aspects of a case and hold the State’s “feet to the fire.”
