Understanding and Knowledgeable

I hired Donny for my family case long after my divorce was over and I really wish that I had hired him much earlier. My first attorney really took me to the cleaners financially speaking. Not that my first attorney did a bad job, far from it, but it was just so expensive. Donny did a great job... for me and he was able to keep the costs under control. My ex is one of these guys who never learned how to simply get along with others. My ex created one problem after another for me and my children. It did not matter that the divorce was over and that the Court had ordered him to do certain things, he was not going to follow any Orders. Not only that, but he kept bringing the case back to court. By the time I hired Donny there had already been over 300 docket entries in my case (which is a ton). That is the thing about court, it is susceptible to being abused by people like my ex who have have regard for the truth. Donny was able to quickly ascertain what my ex was doing and he devised a strategy to defuse the case. And when the judge made an incorrect ruling on one of the key issues in the case, Donny refused to let it go. He argue with the judge and when it became clear that the judge was not going to change his mind, Donny did what he needed to do in order to get a speedy appeal on the issue. I really got to see Donny's full range of legal skills. I not only saw him prepare and execute a trial, but then I also saw him prepare a professional legal memorandum for the appeal. He was excellent. His work is polished and persuasive, which is why we won the appeal! When my ex brought the case back again after that, Donny once again did a very effective job bringing things to a quick end. Donny knows how the system works and he knows pretty much everybody in the courthouse. He knows how to get results. My ex has not brought be back to court since being beat by Donny. And to think that he did it all at a price that I could afford, I really wish that I had known to go talk to him during my original divorce case. If you are reading this review then it probably means that you need a lawyer. There are so many lawyers out there and you should find one who suits your needs, but by all means make sure that Donny Knepper is one of the lawyers you talk to before making any final decision.

Outstanding and Profissional

Mr. Knepper is an outstanding attorney. I hired him in a couple of cases and in both he prevailed. He's well respected by the court staff and Judges. I dealt with lawyer in other cases but if I would recommend a lawyer it will be Mr.Knepper. In the family case Mr. Knepper knew what needed to be d...one and got the job done. I'm very happy with his work and ethics. He's a senior attorney and fees are very reasonable. I'm very happy I hired him and I would recommend him to family and friends. Really outstanding.

Excellent, knowledgeable and Effective Attorney

I retained Attorney Knepper for a case involving a parental custody agreement recently. From the initial consultation to the end, he displayed extensive knowledge and rigor regarding parenting laws in the State and offered very solid advise and alternatives. He successfully executed a very excellent ...agreement at the end despite numerous challenges from the other side. I will definitely recommend him to anyone seeking assistance regarding parental/custody issues.

Fair, knowledgeable, dependable & trustworthy

We had a very complicated custody and child support case and needed an attorney who knew the law, could be a helpful resource, and serve as a forceful advocate when needed. Donny is very knowledgeable about current case law and was on top of our case every step of the way. He is the type of attorney... that you want on your side and fighting for your interests. We appreciated the way he did not bill us for unnecessary work and treated us fairly throughout the process. He is dependable, a great communicator, and a true people person. We feel fortunate to have had his counsel throughout what was a very stressful ordeal for our family. We have and will continue to refer Donny to anyone that is need of a trustworthy, effective, talented, and knowledgeable attorney.

Relationship: Opposing Counsel on matter

"I endorse Donny Knepper without condition. Donny is an exceptionally talented attorney, who knows the court system well and has strong mastery of civil procedure and litigation tactics. 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. It is easy to see why he has made a strong name for himself in the Maryland legal community. Also, as a former (always) U.S. Marine, he brings that diligence, ethics and controlled aggressiveness that is so important for a successful trial attorney. The Maryland Judges and Magistrates seem to recognize this, and give him the respect that is rightly due."
