  • Criminal Defense With A Focus On DUIs 100%


After working for firms and handling numerous cases, I realized that one of the most important things to clients is having an attorney who understands their case from start to finish. When one hires a firm they often never hear from the attorney they originally spoke with again because that attorney only is in charge of intake. The person may not even have the opportunity to speak with their attorney about their individual case before making a payment and instead, their consultation might be referred to a case manager following a script, who may or may not be an attorney. Other times a person's case is transferred to various attorneys within the firm who may or may not know the details of the case. This can sometimes cause confusion with expectations, desired outcomes, probability of success, or frustration with the need to continuously repeat information or provide documents.

It is largely for this reason that I decided to start my own practice. When you hire me you can rest assured that I will be your attorney from start to finish. Your free initial consultation will address your goals and expectations from the start so you can decide whether to proceed with my representation. Thereafter, you can be assured that I will remain a part of your case until the end and will be in direct communication with you.

Since being admitted to the California Bar in 2010 and the Arizona Bar in 2014 I have focused almost entirely on criminal law. Arizona has some of the harshest laws and penalties in the country for common crimes such as DUI/DWI, and it is my goal to ensure that your rights are nonetheless protected. You may have a defense on constitutional grounds such as an unreasonable search of your vehicle, invalid stop, or violation of your rights to remain silent and obtain counsel. The law is consistently changing and I am focused on coming up with the best strategies to protect your constitutional rights.

Furthermore, I am an executive member of the American Association of Premier DUI Attorneys. Through this organization I have become up to date on the procedures that the officers are required to use in order to determine whether a person is impaired due to alcohol and drugs. Through the use of these manuals and procedures I am able to specifically question the officers on their methods to challenge the results and show why the person was not actually impaired.

If you are charged with a crime, give me a call and find out how I can assist you.
