Attorney Information
Overview
Following a successful career as a social worker, Mark began his law career as a solo practitioner, opening his first office in his home. Since that time, he has added Alyssa Phillips, a well-respected family law attorney, to the firm and has mentored several young attorneys who have now moved on to open their own successful law practices. Practicing throughout Northern Virginia and the Virginia Piedmont regions, in both state and federal courts, Mark has represented clients charged with everything from the simplest traffic violation to capital murder, including 30 homicide cases and 150 felony trials.
Mark is well known for his expertise in sex crime defense. He has represented clients in dozens of sexual assault cases and is valued by his peers as a consultant for sex crime defense and trial strategies. As a former investigator of child sexual abuse, he brings a unique perspective to the defense of these cases.
A newly formed collaboration with Walker Jones, PC now finds Mark working with peers who bring additional experience in criminal defense and prosecution, adding this element of expertise to the defense strategy for clients. This combination of viewpoints builds the best legal defense available to clients of the firm.
Mark has spent his career helping people through the most difficult times of their lives and in doing so has become a highly respected defense attorney. He considers each person, the facts of the case, what the defenses are, and works to assertively represent the interests of his client at every part of the process, sometimes negotiating a favorable plea deal or defending before a judge or jury. This focus on the interests of those he represents and his effort to obtain the best outcome has earned Mark the loyalty of his clients, many of whom continue to make referrals to him.
When Mark is not working, he spends time with family, works in his yard, reads and takes care of his goats and dogs.
