Defense Built Around Who You Are

We spend considerable time learning who our clients are beyond the incident bringing them into the criminal justice system. Their childhood, education, employment, relationships, mental health, addiction history, trauma, family responsibilities, and aspirations all matter when they bear on the case. Our clients are people with families, careers, responsibilities, struggles, and circumstances worth understanding.

We also distinguish between winning a legal argument and securing an outcome that improves someone’s life. Avoiding incarceration, preserving professional licensure, protecting employment, preventing a conviction, or avoiding unnecessary probation sometimes matter more to a client than an abstract legal victory. This means we ask about your job, your license, and your family before we recommend a path.

Why Everything Matters in Your Case

One concept has defined our practice for years: Everything Matters.

Details like these shape how we build a defense:

  • A police report detail – A seemingly insignificant detail in a police report sometimes reveals a constitutional issue.
  • A previously unidentified witness – A previously unidentified witness sometimes changes the trajectory of a serious felony prosecution.
  • A childhood experience – A childhood experience sometimes explains conduct which initially appears inexplicable.
  • A conversation with a prosecutor – A conversation with a prosecutor before the first court appearance sometimes changes the direction of a case.

Criminal defense requires the ability to be a litigator and a counselor. We must be willing to challenge the state aggressively when the law or evidence demands it, but equally willing to pursue practical, humane resolutions when doing so serves our clients.

Criminal Defense and Personal Injury Cases We Handle

We are aggressive litigators and pragmatic problem solvers. Our criminal defense work covers misdemeanors, felonies, and traffic matters, and our personal injury practice represents people injured because of another person’s negligence.

Our attorneys represent clients in matters such as:

  • DUI/DWI defense – We weigh what a charge means for your license, job, and family.
  • Traffic offenses – We handle serious traffic offenses in District Court and Circuit Court.
  • Misdemeanor and felony charges – Theft, assault, firearms, sex offenses, and homicide, handled with investigation and witness development.
  • Juvenile matters – We consider the effect on your whole family.
  • Probation violations – We test whether the facts support the alleged violation.
  • Personal injury – We represent people injured because of another person’s negligence, with contingency fee pricing for qualifying matters.

    "Mr. Lake's reputation for integrity, diligence and competence which he earned as a former Assistant States Attorney and while he has been in private practice aided him in achieving the result he did."
    I am a retired Attorney who recommended a personal friend to Justin Lake. I received his name by speaking with an old friend of mine who is still considered one of the top criminal lawyers in Maryland. My friend was clearly guilty of driving while impaired as was evidenced by a video taken at the scene by the investigating officer and the fact that he failed the breathalyzer test. A verdict of Probation Before Judgement or Guilty would have been life altering for him and his family in that it could have resulted in his deportation from this Country and the absolute prohibition of his being able to apply for admission of his family in to the United States. My friend had learned that he had been granted asylum three days before he was charged. Aside from that charge he had an impeccable record. He is employed by a continuing care community where his service is valued which is evidenced by the excellent job reviews he has consistently received. Mr. Lake was engaged to represent him and charged a fee customary for representing someone charged with such an infraction. I know from my experience that he expended far more time on the case than he was compensated for, but he did not ask for an increase in the fee. He spoke multiple times with an Assistant State's Attorney of the County as well as the States Attorney, removed the case to a higher Court and with the Assistant State's Attorney met with the Circuit Court Judge of the County. At that meeting Mr. Lake introduced a legal opinion prepared by my friend's immigration attorneys with whom he conferred which set forth the aforementioned consequences that would ensue were any judgment aside from a PBJ(C) entered. It is the only judgment that would not impact his and his family's immigration status. Such a judgment is extremely rare. I am of the opinion that Mr. Lake's reputation for integrity, diligence and competence which he earned as a former Assistant States Attorney and while he has been in private practice aided him in achieving the result he did.

Your Legal Defense and the Context Behind Your Case

One distinction we frequently discuss with clients is the difference between a factual or legal defense and the context surrounding the allegations. Each matters and serves a different purpose.

Our attorneys separate the two when evaluating your case:

  • Factual and legal defense – We evaluate the evidence, identify weaknesses in the prosecution’s case, and determine whether the State is able to prove the charges beyond a reasonable doubt.
  • Context – Even when the underlying facts are difficult to dispute, there is often a larger story about how and why someone found themselves in the situation. This story informs mitigation, treatment opportunities, plea negotiations, and alternative resolutions.

Our job is to understand the case and the person. We know when to challenge the State’s evidence aggressively, when to focus on mitigation, and, frequently, how to use the two approaches together to pursue a favorable outcome.

Local Courthouse Experience Across Maryland

Although our office is based in Howard County, we regularly represent clients throughout Maryland and in federal court. Criminal law applies statewide, but criminal practice is intensely local.

Howard County is our home jurisdiction, and we’ve developed some of our deepest professional relationships and experience in its courthouse. We regularly handle matters in District Court and Circuit Court, including DUI, serious traffic offenses, firearms prosecutions, assaults, theft, juvenile matters, probation violations, and serious felony litigation. 

Our familiarity extends beyond courtroom procedures. We understand the practical importance of communicating with prosecutors, identifying appropriate treatment resources, presenting meaningful mitigation, and addressing issues before they become obstacles to a favorable disposition.

Our approach changes with the courthouse:

  • Carroll County – Our Carroll County practice includes criminal, traffic, and probation matters in District Court and Circuit Court. We’ve tried cases, negotiated charge reductions, coordinated resolutions across multiple proceedings, and arranged sentences focused on treatment and rehabilitation.
  • Anne Arundel, Baltimore, Harford, Frederick, Montgomery, and Prince George’s Counties – Prosecutorial discretion, diversion opportunities, plea negotiation practices, sentencing expectations, and courtroom procedures vary by jurisdiction and even by individual courtroom. An approach that works in Howard County often requires adjustment elsewhere.
  • Federal court – We also represent clients in federal court.

We don’t assume a particular prosecutor or judge will handle a case the way another does. We evaluate the jurisdiction, the nature of the allegations, and the available procedural and negotiated options before determining our strategy.

The Attorneys and Recognition Behind Your Defense

Our attorneys bring more than 50 years of collective legal experience to your case. David Zwanetz has devoted his practice exclusively to criminal defense since 2005, handling thousands of cases and numerous jury and bench trials. 

Justin Lake spent nearly four years as a Howard County Assistant State’s Attorney, prosecuting thousands of DUI/DWI and misdemeanor cases before moving to major felony matters. His prosecution experience informs how he evaluates the State’s evidence.

Our attorneys and firm have received this recognition:

  • David Zwanetz – Recognized by Super Lawyers and Avvo.
  • Justin Lake – Super Lawyers Rising Star and 2023 Best Lawyers: Ones to Watch in America for Criminal Defense: General Practice.
  • Our firm – 2026 Best Law Firms Regional Tier 1 in Baltimore for Criminal Defense: General Practice and Regional Tier 2 for DUI/DWI Defense.

Recognition reflects our work and doesn’t predict the result in your case.

In turn, we need you to give us the information required to evaluate your case accurately and develop an effective strategy.
