Analyze, Strategize, and Advise

The first step is to review your case and the government’s evidence against you. You will then be presented with a legal opinion and an honest, thorough, and educated evaluation of your case, the likely and possible outcomes, and the plan for the best course of action. 



The first goal is always to have the case dismissed. We will gather evidence and any other tools that might help us to convince the State to dismiss your case. If that is not possible, we will discuss potential plea offers and negotiate with the State to get the best deal. 



If a dismissal or favorable outcome cannot be obtained through negotiation, then it’s time to fight. You and your witnesses will be prepared, and all evidence gathered and analyzed to prepare for trial. With over a decade of experience at winning trials, every available tool will be used to present the best possible defense. 

These are the next steps in your defense.

Experienced. Respected. Tested.

The decision of which lawyer to hire is crucial when you have been charged with a crime. Your future, freedom, and even your life could be at risk. Many lawyers make claims about their experience and various organizations sell badges to be displayed on websites such as "top" or "super." To become Board-Certified, applicants must be approved by a minimum of ten judges and other lawyers, have a certain number of years in practice, a certain number of trials and appeals in criminal law, and pass a comprehensive day-long test. Board Certification is the only credential recognized by the State Bar Association that ensures the lawyer is an expert in their field and the best choice for your trust.

Brad was great from the moment he looked at my case. Despite his busy schedule, he made himself easily available, walked us through every detail with care and professionalism, and worked out a great deal with the prosecutor that was much better than any outcome we could have imagined. I don’t plan on needing his assistance again, but if I’m ever unfortunate enough to find myself in another legal bind, Brad will be my first call.

Brian F.

I have had the opportunity to know Brad both personally and professionally for a while now. As a fellow attorney, I am consistently impressed by his passion and innovative approach to legal issues. He is exceptionally intelligent and is always willing to go above and beyond for his clients. When I refer clients to Brad, I have full confidence that they will receive top-quality representation.

Brad is an amazing attorney, and I highly recommend him! He has deep knowledge and understanding how to navigate the law to support his clients. He has a way with people, and truly has his focus on client care and supporting them, during a time that’s usually stressful for clients. He was able to support in getting my case dismissed in less than 2 months and was attentive and personable during the whole process. You have a choice when deciding who’s going to represent you, and to have an attorney that genuinely cares for his clients should be an expectation anyone should set. Brad will meet that expectation 110%!

[Brad] made the process very easy for me, handling everything within a month, with a motion to dismiss all cases against me. I only had to attend court once! The portal he uses to make sure you are aware of everything going on in your case is awesome, I didn’t even have to worry everything got downloaded to the portal with email notifications. I would never use another attorney to represent me, he is the best at what he does.
