Free Consultation

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

Great Lawyer!!!
I hired Mr. Parven to represent me in a case involving an overweight and a criminal offense while driving a commercial truck.

Straightforward and informative
I was pulled over in Blythe, CA for going 105 in the 75 MPH zone headed toward AZ. I of course got hit with the 100+ speeds charge and was immediately in distress. Of course I should have not have been speeding at all but it is what it is. When I came here for legal advise on whether I should even...

Upmost integrity and professionalism
Mr. Parven Contacted me on a question that I had posted. After discussing my case and everything I had already done. He advised that it wouldn’t be fair if I hired him or any other attorney as I had already did every myself. He told me to keep him informed on the outcome of pre-trial conference. ...
Thank you for your kind review. One of the main benefits of hiring an attorney is it will save you lots of time and worries because you won't have to deal with the hassles of the court system. It is always advisable to contact an attorney from the start to maximize the benefit you will receive. In most cases it is also advisable to have an attorney to fight for your rights throughout the process to maximize your chance of obtaining a favorable result. However, every case is unique, and occasionally, for minor cases, the cost of an attorney might not be justified if you have the time to do it yourself. I believe it is important to give honest and detailed consultations to ensure you know you are making a good investment when hiring an attorney.
