"Mr. Petrovich assisted me in dealing with an FBI investigation. His involvement led to its resolution. Based on this experience, I give him my highest recommendation. When I presented him with my story, he took the time to listen and discuss it very thoroughly, providing insight along the way into my potential legal liability, what interactions I might have with the FBI, and his outlook on my case. Mr. Petrovich's empathy and direct conversation with me demonstrated his consideration for my concerns and circumstances. He continued that pattern of understanding yet direct communication when he reached out to the FBI on my behalf. Involvement with the federal government's investigative bodies feels intimidating, but this attorney's assistance made me feel that I had an honest advocate who knew my story and my interests and would fight for them. Thanks to Mr. Petrovich's help, my situation resolved without further issue."

""Mr. Walsh assisted me with a DUI case in Fairfax County that involved an accident in 2024. I was expecting to serve at least 5 days in jail, at a minimum. After Mr. Walsh deliberated with the prosecutor and the police officers, my case was downgraded to a misdemeanor to my total surprise. This a man is a true master at what he does. In my view, he is the BEST attorney in the county for traffic violations. I highly recommend him."

My experience working with Mr. Petrovich was excellent. He gave me great advice, kept me well-informed throughout the process and resolved my situation quickly. I highly recommend Mr. Petrovich and his firm.

My journey as Mr. Petrovich' client began on a Friday before a 3 day holiday weekend. I called about 7 times (!) because I thought I had a deadline. His team answered my calls every time and when he was free, we were able to review my case.

From there, Mr. Petrovich personally excavated the history of my case. He was able to determine where there were missing pieces and where there were opportunities to move forward. He represented me in court with the professionalism the judge appreciated.

I am grateful that he was there at a time when I was close to losing hope and I appreciate knowing I chose the right attorney.

I have just recently gotten through a court case with the help and representation of Mr. Petrovich. This was my first interaction with the law and Mr. Petrovich’s guidance, patience, and compassion can not be forgotten. He made it so I had a clear understanding of my situation while still helping me maintain a level of calmness. I am forever thankful for his advocacy. I couldn’t have been blessed with better.

Late November in 2018, I was arrested in Prince William county and charged with 1st degree murder & use of a firearm in the commission of a murder & was facing 25 years to LIFE in prison. While Incarcerated I went though two different lawyers before I was given Mr. Thomas Walsh’s number from a friend of a friend after he handled her case and got her charges completely dismissed. After meeting with my parents then me he was hired. Mr. Walsh came by and interviewed me in jail and started his own investigation on my case. Mr. Walsh got down in the streets and tracked down witnesses along side his investigator and where able to find witnesses , address and homes of incidents correlating to my cases investigation , witnesses that police nor detectives on the case never interviewed or investigated !! Mr. Walsh worked day and night tirelessly while I was in jail incarcerated waiting for trial. After a year of being incarcerated Mr. Walsh got me bond when there was almost no chance of bond considering my murder charge. After staying on bond for two years Mr. Walsh was prepared to go to trial and was looking forward to the trial as he was well prepared and confident in my defense. The Prosecution knew Mr. Walsh knew the case better than anyone, including the police and detectives. The case was concluded to the prosecution amending and reducing my murder charge to a lesser charge and offered me a no contest plea and time served for which I served 1 year before bond.

Tomas Walsh is an amazing lawyer! and everyone that works along side him, they treated my family with respect and love during and after the case. I Thank God and am Grateful for Tom & his Great Experience. I would recommend Tom and trust him with anyones legal needs any day!

Attorney Mark Petrovich defended me when I had a Federal charge in 2012.  I had the best outcome I ever expected. I read about his services earlier through Google by searching the list of the best attorneys in Fairfax, and that is how I found Petrovich & Walsh, P.L.C.  I read about five possible attorneys, but I chose Mr. Petrovich.  I am more than satisfied with his service.  Mr. Petrovich has the experience, knowledge, and outstanding ability to defend the client in court.

Last year, I was charged with a misdemeanor: reckless driving at 105-mph in a 65-mph zone.  When the police officer told me the charge, I broke down in tears.  I could not believe what I heard and the possible consequences.  I called the legal assistant Debra Wright to arrange a date with Mr. Petrovich. I cannot trust any other lawyer, and I was correct. For the second time, I was saved by him.  Because of his extensive knowledge and extraordinary litigation expertise I left the courtroom free of charge. More than that, my stress was relieved because I had been in a serious legal problem.

I can only be always grateful to Mark Petrovich for having addressed my cases in the best way possible. I have recommended him to friends, and the result is always positive. There is no question of his competitive ability as a lawyer.

Petrovich & Walsh, P.L.C.  has an excellent staff.  You can be sure that every penny paid will be worth it.  In this firm, there is no misleading information, there are no false promises, and there are no hidden fee charges.  The firm will not waste your time on appointments and consultations; they will take care of your case.  Please call Debra Wright to make your appointment to solve your legal problems with the best law firm I have met in the entire area, especially attorney Mark Petrovich.

“Mr. Petrovich came recommended to me from two different sources and both were absolutely correct in their assessments of his expertise. Mr. Petrovich proved to be highly professional and knowledgeable. I felt comfortable with his advice and guidance, which led to a win for me! The office location and parking are in perfect distance of the courthouse. I would highly recommend this firm for your legal needs.” -T.L.

I truly recommend Tom Walsh to anyone that needs a great lawyer. Tom has worked tirelessly to ensure the best outcome on my behalf, I am grateful for his passion, dedication and professionalism. He is the best lawyer I've ever worked with. I can't thank him enough. - V.S.

“Mr. Petrovich and his staff were very helpful and responsive to all my questions and concerns about my case. He was able to resolve my situation in the difficult times of COVID 19. He was very professional, responsible, and attentive to my situation. Overall, it was a pleasant experience to work with Mr. Petrovich!” -N.M.

“I was charged with a misdemeanor and was extremely nervous with what could potentially happen to me. Fortunately I had the privilege of contacting Tom Walsh and his paralegal Debra. Tom immediately impressed with his vast knowledge of the Fairfax County court system. He is a well respected attorney who works with the prosecution and judge to come to an equitable agreement. He is able to put your mind at ease by explaining all the potential options that are available. Because of Tom, I was not required to pay a fine or have jail time. I would highly and completely recommend him to handle your legal needs.” -A.Z

“The last thing you ever want to do is be sitting in a lawyer’s office, especially when it comes to your child.  I cannot thank Mark enough for his compassion, his time, his dedication and his guidance.  He made a stressful situation bearable and assuaged the fears my daughter and I had, while also being realistic and prepared us for the worst outcome. He spoke to my 16 year old in a way that she would understand and guided us through the situation, not with fear but with knowledge. Although we had a positive outcome to our situation, that was solely due to Mark and his exceptional capabilities.  Thank you Mark. I would recommend him to ANYONE with a juvenile situation and I credit him with saving my child.” -Tanya H.

“I highly recommend Mr. Petrovich as a defense lawyer, based on my personal experience.

My case concerned an evolving area of law where there is a lack of historic precedence for case development and defense preparation. His systematic approach to my defense incorporated quantitative data presented in a clear timeline that logically addressed the key charges against me but also provided the flexibility to address and refute a number of side issues that the prosecutor tried to introduce.

Mr. Petrovich’s preparation was very thorough. He attempted to have the charges dismissed or reduced but the prosecutor was adamant there should be a trial.  In court, Mark was respectful but quietly aggressive, citing witness inconsistencies and objecting frequently when the prosecutor strayed into side issues or repetitive presentations.

The best measure of satisfaction is often the outcome and that was the case here.  I was extremely pleased to receive probation, an outstanding resolution to a difficult case in a still-developing area of the law.  Mark is an outstanding advocate for the defense.” - Joe D.

“I was charged in Fairfax County with a DUI and was concerned about my career and my security clearance. I was referred to Petrovich & Walsh, P.L.C., and retained Thomas Walsh to handle my case. I was very comfortable with Mr. Walsh and his professionalism and knowledge of the law. The prosecutor offered for me to plead guilty to the DUI with minimum fines. Mr. Walsh suggested we proceed to trial and the Judge threw the case out finding me not guilty. I was concerned with my case but relied on Tom Walsh’s experience and it paid off.” - Bob R.

“I had never needed legal services before and was fortunate to locate Petrovich & Walsh, P.L.C. What stood out for me (in comparison to other lawyers) in my first meeting with Mr. Petrovich was his genuine concern, ability to ask precise questions to understand the case, and professional demeanor. I felt that his legal service fees were comparatively reasonable – which was relieving.

I am very glad that I decided to hire him as the attorney for my case. He and his very helpful legal staff went about executing the legal process in a very timely and professional manner. Because of his detailed prep work and intense litigation skills, I was acquitted of the false allegation made against me. I would highly recommend to avail to Mr. Petrovich’s legal services!” - Vin A.

“I am a former Marine. I served honorably for nearly 9 years and I also served as a police officer for 2 years before my arrest. In October 2011, I was originally charged with a misdemeanor of assault and battery after protecting my family from an intruder that attacked me. I defended myself and hit the aggressor 3 times and one of those punches just happened to break his jaw. I thought that with my outstanding, unblemished record as well as my professional record of being a veteran as well as a law enforcement officer, that this would be a clear case of self-defense. But, instead, it turned out to be a lot more than that.

A few days later my charges were upgraded to malicious wounding, which is a serious felony in the State of Virginia not to mention that my career and future were in great jeopardy. After this I knew I needed not just a good lawyer but a great lawyer who knew the law and would consider my case important and not just another case on his list of things to do. A high ranking attorney with the justice department referred me to Mr. Tom Walsh. After meeting with Mr. Walsh and hearing what his plan was for the case moving forward I knew that he was the lawyer for me.

During the course of the case, the prosecutor changed three times and this was not the type of change that would merit something good. It was an overwhelming charge in the first place but, when the prosecutor changed, my charge was again upgraded to aggravated malicious wounding. In Virginia, a person can serve 20 years to life in prison for that.

The case itself went on for just over 2 years and at certain points it took its toll on both my family and me and I am more than certain that it took its toll on Mr. Walsh, as well. But rather than give in and look for plea deals for me, Mr. Walsh took considerable time away from his personal life to fight for me. He put in the type of effort and fight that a Marine would put in to fight for his country. I should know.

I was ultimately convicted of just a misdemeanor of assault and battery, no jail time and I only had to pay a small fine. I open my personal life up in this testimony to get the word out for all Veterans and anyone else who might be struggling to find someone that cares and will give their all to fight for you. I have seen firsthand how prosecutors will try to destroy a person’s life and make them another example. Well, I am here to let the world know that if Mr. Walsh fought for me, he will do the same for you.” -K.G.
