What Mark B. Williams & Associates, PLC does

Mark B. Williams & Associates, PLC is a Warrenton, Virginia-based law firm founded in 1990 by Mark B. Williams that provides legal representation to individuals and families throughout Northern Virginia. The firm operates three core practice areas: criminal law defense (covering DUI/DWI, traffic violations, sex crimes, homicide, drug crimes, white collar crimes, weapons crimes, and domestic violence), family law (divorce, child custody, adoptions, fathers' and grandparents' rights, protective orders, and property division), and personal injury (auto accidents and wrongful death), with ancillary services in wills and trusts, gun rights reinstatement, and driver's license reinstatement. Two named attorneys anchor the practice — founding attorney Mark B. Williams (admitted 1990, with 30 homicide cases and 150 felony trials to his credit) and associate Alyssa D. Phillips (20+ years of family law experience and a Neutral Case Evaluator appointed by the Fauquier County Circuit Court since 2011). The firm also maintains a newly formed collaboration with Walker Jones, PC to supplement its defense perspective.

The firm makes money through two primary revenue streams: hourly billing for criminal defense, family law, and traffic violation services, and contingency-fee representation for personal injury claims where clients pay only upon successful recovery. Free initial consultations are offered across all practice areas, and evening and weekend appointments are available on request. Geographic coverage spans Fauquier, Culpeper, Rappahannock, Prince William, Warren, Clarke, Fairfax, Page, Frederick, Madison, Orange, Stafford, Spotsylvania, and Shenandoah Counties, plus the cities of Warrenton, Front Royal, Winchester, Manassas, and Fredericksburg.

The underlying technology is essentially none — this is a traditional professional services firm with no proprietary software, AI/ML capability, API, or digital product offering. Distribution is via a single headquarters office at 27 Culpeper Street, located steps from the local courthouses, supported by a content marketing program (website, blog, Facebook, LinkedIn) and Spanish-language accessibility. The firm has not raised external funding and is owned and operated by its founding attorney.
