“I just want to say if you want a case to be taken seriously and not be judged by age or any other factor I will tell you stop your search here! Mark is outstanding and is on top of his game. He is well educated and knows his stuff. I hired mark for a dui and a hit and run both were dismissed !! I knew I had to find the right layer to her my side and that is what Mark did ! He listened he fought and now Im here giving him a 10/10 for his service . His team is also very helpful answering calls and even answering questions that can be answered depending on the question and what reg it falls under. I am so happy and pleased I hired Mark!”


“I hired Mr Girdner as representation when I was arrested for a DUI involving a minor collision while visiting CA from out of state. Mr Girdner not only took care of it without my having to return to CA, but he was able to get all charges dropped. It took nearly two years and several offers from a couple different DAs, but he was finally able to secure an agreement to drop all charges. His retainer was affordable and his demeanor was very comforting because he seemed so knowledgeable. He was sensitive to my concerns and though I felt like his office could have called to check in more, when I called someone always answered or called back in a timely manner. I highly recommend Mr Girdner to anyone dealing with a DUI or DWI.”
