Posted by Jorge | October 30, 2016 | Hired Attorney | DUI & DWI

Great, knowledgeable, personable, and connected lawyer

I hired Donny for a first-time DUI case. He was clear and articulate about my options from the start. He was realistic from the start and offered sound legal advice. At the end, Donny was able to get me a Probation Before Judgment by haggling directly with the prosecutor in trial. He was very strong ...and well-spoken when speaking and presenting my case to the judge. Donny knows what he is doing and knows the judges, lawyers, and police department in his jurisdiction. I'd recommend Donny, hands down.

Fantastic Defense Attorney

I hired Mr. Donny Knepper to represent me in a very serious DUI case. This was my first time being in legal trouble of any kind, so I didn’t know much about the process. After my arrest, I received dozens of offers to be represented by various lawyers in and around Montgomery County, Maryland. ... I contacted and consulted with many, but I knew from the first conversation that Mr. Knepper was the attorney for my case. He was kind and reassuring from the very first conversation we had on the phone, which he answered himself after normal business hours. He offered a very prompt, thorough initial consultation. After learning the complicated nature of the case, he offered me a very fair flat fee with a structured payment schedule. As a father of four, this was a godsend. Before my initial consultation ended, he had zeroed in on a solid, multi-pronged defense strategy. This gave me great peace of mind as I went on about my busy life until my court date. On the day I appeared in court, Mr. Knepper arrived and spoke with the district attorney who offered a deal that was not satisfactory. He laid out my options in plain terms, and advised me that we should take the case to trial, because he had a well-researched, viable argument. He had done his due diligence and had various legal cases to cite in front of the judge. Although I was very scared and nervous, his composed demeanor and confidence in his position reassured me. I took his advice and we went to trial. He defended me like a lion during the trial. All of the police involved in my arrest were there to testify against me. He aggressively objected to any unfair testimony and shut down much of the district attorneys arguments. He stuck to his initial position, the one he zeroed in on back at our first consultation. He got the officer who first encountered me to admit he made a mistake and set them on their heels from that point forward. Almost none of the evidence against me after that really had much bearing. In the closing arguments he made a motion to have the charges dropped, and the judge agreed with him. I was acquitted of all seven serious criminal charges, as well as one civil charge. Their entire case was complete gone. This man saved my life, my marriage, and my career. The outcome he achieved has saved me years of legal and financial woe. I would tell anyone looking for competent legal representation to go with Mr. Donald Knepper.

Awesome!

I couldn't wait to get home and give this review. This man is a great lawyer by all mean. I hired him for a DWI case and he came through for me. He's very reassuring and confident. The case wasn't dropped but he did all he could and got me the best option possible. It was my fist time dealing with an... issue like this and he made me feel comfortable and even when I was losing faith and freaking out he calmed me. I would definitely recommend him and his team to anyone that needs a lawyer.

In it to Win it!

I would recommend Donny to anybody in need of a lawyer. I hired him to handle what would have been my second DUI. I told him that I was being wrongly accused. From the very beginning of the case Donny did everything he could to make sure that I was found not-guilty. He visited the scene of my... arrest. He took pictures of the area and got them blown up in HD quality color photos. I knew that a lot of people had witnessed my arrest and Donny talked to every one of them. I could tell that winning was important to him. I've had to hire a lawyer before. I know how it is. You sort of wonder whether you are giving your money away. You wonder if the lawyer will really do anything for you. Let me tell you, Donny works. There was a legal issue that popped up in my case and Donny was all over it. He wrote this whole long motion. Even when we lost in District Court, he just took it to Circuit Court and kept at it. It was like no matter what happened he would find a way to win. I cannot tell you how happy I was the day that Donny called me to tell me that the prosecutor had finally had enough and was dismissing my case. Justice prevailed, but I know that it would not have happened if I did not have Donny Knepper on my side. If you are looking for a lawyer, do yourself a favor and call him.

Hardworking, Compassionate, Diligent -- A Superb Criminal Defense Attorney

When I was arrested for DUI, I felt like my future hung in the balance. I was facing the possibility of jail, and a ruined future that would limit my career choices. I dealt with the personal issues first and made a major life change by deciding to quit drinking. I took responsibility for my mistakes.... However, on the night of the incident, I had been overly cooperative with the police and had been in the bar waiting for them to arrive after a heated discussion over a parking place. The stress of my looming court case was having a toll on my personal life and ability to concentrate at work. My mail was full with marketing letters from various attorneys and I was unsure who was the best choice. I decided on retaining Donald (Donny) Knepper, which was one of the best decisions of my life. Donny took the time to understand me as a client, and as a person. He concentrated on the facts of my case and understood what happened that night. In preparing for court, Donny left no stone unturned and no detail unchecked. He always kept me notified as the case progressed, and explained the complicated judicial process in plain terms that I could understand. When it came time for court, and in the judicial process, Donny always wisely advised me of my options and interpreted their possible outcomes. I felt confident that he was doing everything to defend my rights and my freedom. On the day of my trial, it was apparent that Donny’s strong reputation as an attorney in the eyes of the court--its officers, the judge, and the state’s attorney were beneficial to my defense. Donny’s skills as a lawyer helped me to be successful in defending the charges against me including his extensive knowledge of the law, judicial procedures, and police procedures. He was able to deal effectively with the prosecution, clearly a testament to their high regard for him personally and professionally. His strong analytical skills, diligent preparation, and effective decision making in the fast-paced trial environment enabled a successful outcome in my defense. There are a lot of choices in criminal defense attorneys. Donny will take the time to understand you as a client and your case. He will work diligently in your defense and be a compassionate adviser as you face your personal and legal issues. There is no better choice as a defense attorney. I wholeheartedly recommend him.

If Donny is the opposing counsel, you had better prepare well for any court event, as he is a forceful advocate for his clients and appears to take every opportunity to advance his clients' interests.
