He will look at not just what the police are saying, but what they are not saying.

Criminal Defense

The government has all the money, the experts, and the investigators from the beginning. You need an attorney who will respond aggressively from the beginning.

At the point you become aware the government is building a case against you, you're already losing the race. At a minimum, they've already begun gathering evidence to use against you. They might have even arrested you. A key strategy to getting caught up and taking the lead is to aggressively attack their ability to continue gathering evidence. The right attorney is an attorney who knows what the government is likely to do and knows how to interrupt the investigation so you can be heard.

David spent over a decade on that side of the equation. Now, he is a defense attorney working to ensure the government doesn't trample on your rights. He begins working the case from a defense perspective. By essentially deconstructing the case and building it in a defensive light, David has been able to get several cases closed before an arrest was made or has had cases dismissed when errors in the government case have been brought to the surface.

You will have the peace of mind knowing someone with the experience the prosecutor relies on is working for your protection.

What experience or education distinguishes your lawyers from others?

David spent over a decade in law enforcement prior to starting his own criminal defense firm. He can work your case with the understanding of how a police officer actually investigates and tries to prosecute a crime. Other defense attorneys, even those who were prosecutors, often don't understand the specific ways police officers work.

What distinguishes your law firm from others?

Unlike many of the larger firms in Arizona, David is the only attorney at the firm who will handle your case. It won't be bounced from new associate to new associate. When you have your consultation, David will speak with you about your case. When your case is being worked, David will be the attorney working your case. When you call with questions or concerns, David will be the attorney helping you. This means you are the primary focus of David's practice.

How did your firm decide on the primary area of practice(s)?

Time and time again, people under investigation for a crime say and do things, or allow the police to do things, that substantially harm their case. The police understand this happens and often work their cases in a way that maximizes their ability to take advantage of what the accused does not know. When David left law enforcement to open his own law firm, he knew he wanted to educate his clients and protect them from these predatory tactics.

"Too often, people are accused of committing a crime supported only by weak evidence or a bad investigation. Before the police can take someone's freedom, they need to do their job extremely well. My job is to expose the weaknesses in the government's case. My career as an investigator allows me to see the case as an investigator sees a case. I can attack it from the inside out."

David grew up in Tucson, Arizona, and began a career in law enforcement as a corrections officer at the Pima County jail. He was taken hostage during an escape attempt and was cut with a shank. The Pima County Sheriff's Department awarded him a Purple Heart as a result.

David moved to Phoenix and ended up a patrol officer with the Phoenix Police Department. After six years working a beat, David became a detective in the Crimes Against Children Unit. He worked serious felony cases from child abuse and molestation to sexual conduct with a minor and homicides for the remainder of his police career.

While working as a detective, David attended law school. He graduated as valedictorian of his law school class and placed first on the Arizona bar examination. After obtaining his law license, David opened his own law firm where he could help defend people accused of committing a crime.

No one should face the power of the government without someone on their side working to ensure the government does not trample on their rights.
