About David
Biography
With almost two decades of legal experiece, I have dedicated my whole legal career to criminal and DUI defense because I love helping people. I believe it is a privilege to practice law and even more so when someone has asked me to help them get through their tough case. What sets me apart from the rest is that I am completely results oriented. I want to get the right result for each client no matter how long it takes. I take pride in serving my clients well. I understand providing excellent service and getting results require hard work, an attention to detail, and preparation.
