Delivering Experienced Courtroom Advocacy For Residents of Northern Virginia Since 2009
The Former Prosecutor Advantage
Prosecutors must know their way around the court system. They must understand how cases are investigated and built and how to spot weaknesses in the opposing party’s case. They quickly learn what arguments resonate with judges and juries – or they don’t last.
McClain Rosenthall Davis, PLLC, is built on a foundation established in 2009 by former local prosecutors who wanted to use their skills to help people affected by the court system. Formed in its current iteration in 2024, our firm provides the highest-quality legal representation for people, families and businesses. We can help you, too.
We have over 45 combined years of experience and have conducted more than 1,000 trials in Virginia’s state and federal courts. This extensive trial-tested background translates to a distinct advantage in matters of criminal defense, divorce, family law and other complex civil disputes.

A Focus On Criminal Defense
At McClain Rosenthall Davis, PLLC, we are second to none in criminal defense. We defend adults and juveniles against state and federal charges ranging from DUI and drug offenses to fraud, violent crimes and murder. We practice throughout Northern Virginia.
Depending on your circumstances, there may be many defense options for you, and we can explore them all. We know how to access diversion programs, negotiate favorable plea bargains and fight for acquittals in court. We also handle probation violations, criminal appeals and record sealing.
An Emphasis On Divorce And Family Law
Our skills and experience translate well into divorce and family law as well. We can help you file for divorce or respond to your spouse’s filing, set up child custody and visitation arrangements, and arrange for child and spousal support. Throughout your case, we will focus on your interests and the best interests of your children.
In addition, attorney Maggy Vaughn is one of only a few lawyers in Northern Virginia who handles adoptions. She can help you build your family through private adoption, second-parent adoption or stepparent adoption.
Our Local Knowledge And Relationships Matter
Over the years, we have built our practice across Northern Virginia, specifically in McLean and Alexandria as well as Arlington, Fairfax, Prince William and Loudoun counties. In criminal defense, we also serve Winchester and Frederick and Stafford counties. That local focus matters.
We know the local court staff, the judges’ preferences and courthouse cultures in a way that out-of-area attorneys simply do not. The local prosecutors are our respected former colleagues. We know specifically what arguments will and won’t work with specific judges, and we are familiar with local procedures that can make or break your case.
