I have been litigating cases in Maryland for almost 20 years, although sometimes I am called on to represent clients in other states as well.   During law school, I gained valuable appellate and criminal investigation experience at the Office of the Maryland Attorney General.   After graduating in 1993, I was law clerk to the Honorable Paul H. Weinstein.  I then served four years as an Assistant State's Attorney in Montgomery County Maryland.    I prosecuted cases on the District Court proseution team, juvenile team, and felony trial team.   Since 1999, my practice has focused on criminal defense, licensing and administrative hearings, personal injury claims, and various types of civil litigation.    I am a member of the Maryland State Bar and the Federal Bar.   I am also a member of the Maryland State Bar Character Committee which is responsible for screening prospective lawyers who are seeking to become members of the Maryland Bar.   My firm represents individuals charged with everything from minor traffic tickets to murder.   When we are not defending someone is a serious felony case, I am also in court every week of the year defending someone charged with DUI, and other relatively serious misdemeanors.   We like to try cases.    I often say: "If we work out an agreement that resolves your case in a favorable manner, you will really like us; but if we take your case to trial and win, you will think we worked a miracle for you."   I am very proud of the work we have done to put people's lives back together by either putting an end to a legal campaign against them, or by getting the legal system to work for the benefit of the client.   We also assist many clients with a wide variety of difficulties before they become legal problems.

Smart, strategic and well-connected lawyer. Highly recommend
I hired Mr. Martella to represent me in what became a complicated mess of a case, particularly given COVID. I had never been in jail before and was confused and scared. He quickly executed an effective strategy, and when external circumstances changed, remained flexible and encouraging. He's well connected around Montgomery County--his knowledge of the players and the system proved extremely helpful. Dave was always responsive and supportive throughout the process--for both myself and my wife. I highly recommend hiring Mr Martella.

The Man who will stay in our heart and in our prayers.
David A Martella is not only an excellet lawyer, before every thing he an humanist, a helper. When we took our case to him, our harts were brook and the futur of our family was dark. Before he consider the case, his first concern was to save us from stress. He took anought time to understand the all situations we were going thru, and told us all the legal options to help us out. He did carry the problem as his own case until the end. He considered help first and not make the money in the client's case. I never meet a man such a sensitive in some body trouble. I will always remember what an old lady told us in the Rockville courtroom when she saw David talk to us. She said: " you will thank God and the person who refered you to that man, because he is the best Lawyer I ever meet in my life, you will not loose your case for sure.'' She was right, because we finaly wont our case in the best way. David A Martella is an excellent Lawyer, but for me he is the best. May God protect him and give him long life, so he can continue to help more people.

Honest lawyer
I was under a lot of stress when I walked into attorney Martella’s office. He was easy to talk to, down to earth, and treated me with respect. He took his time to listen to all the facts and asked many questions before explaining of what was going to happen and giving me great counsel. Then he revealed his honesty when he determined that there was no need for me to hire him. And he refused to accept a payment for almost an hour of his time. I left his office with a good understanding of what was going to happen, well-advised and relaxed. Thank you David.

Top Notch!
Top Notch! David worked miracles in the court, as if he had the staff of Moses in his hands--heart and soul, along with a quick grasp and a keen eye into the intricacies of the law. Mr. Martella is a honest, decent, and noble gentleman of noble descent with a touch of God. My family and I extend our love, gratitude, and appreciation with heartfelt thanks.

Top-Notch Criminal Defense Attorney in Montgomery County, MD
Dave is a well-known, and very well respected criminal defense attorney in Montgomery County. I have now seen that reputation at work first-hand (unfortunately for me), and it is well deserved. Dave is smart, logical, cares about his clients, and knows his way through the entire system. He always went above and beyond the call of duty when an emergency arose, whether it be late at night or on the weekend. Would hire Dave again without hesitation, though I hope I will never have to do so.
