Posted by anonymous | February 26, 2017 | Hired Attorney | DUI & DWI

Couldn't be happier

I was lucky enough to get Mr. Knepper as my attorney for my first (and last) DUI. I was expecting the worst in terms of fines, community service, and possibly jail time. Mr. Knepper made me feel comfortable and confident from the moment we began speaking. He handled my case very promptly and diligent...ly. He was easy to be reached, kept me informed, and was always very friendly and positive. I feel Mr. Knepper took steps with my case others would not have. He challenged my case and was able to get me acquitted. I could not be more pleased with the outcome Mr. Knepper achieved for me, and I 100% recommend him.

Posted by Margaret | September 18, 2014 | Divorce & Separation

Integrity, Hard working, Compassionate, Experienced, THE BEST ATTORNEY!

In 2009, my spouse left me with two disabled children, but that was not the most horrible part. When he filed for the divorce, he told the court that I was a drug infested mother who abused her children. I interviewed six attorneys, and when I told my story to Mr. Knepper, he was genuinely concerne...d for me and my children. I hired him, and immediately, he went to work. He was very organized and timely with my case on all issues. He always returned my calls the same day. Mr. Knepper properly prepared by case by ensuring I had all the evidence on hand and proper witnesses. When my divorce case was over, I had full custody of my children, a monetary award (greater than expected), child support, and my reputation restored as "the perfect mother". I left the courtroom, and I was 100% pleased on how he handled my case. He's personal, courteous, hard working, and simply the BEST! Most impressive, he checks up on me and my children on a regular basis. He's represented me three other times since my divorce case. So, Mr. Knepper is my family attorney, and I would never trust anyone else. If you need a damn good attorney, please consider Mr. Knepper. He was a Marine. He fought hard for this country, and he'll fight hard for you!

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."
