Simply excellent!
Recently, I had the pleasure of working with Mr. Rosenthal on a legal matter. I selected Mr. Rosenthal based on reviews. I am glad that I made the right choice. I was impressed with his level of expertise, attention to detail, and overall professionalism. He was always available to answer my questions and address any concerns I had, and kept me informed every step of the way. I never felt like I was in the dark or left wondering what was happening with my case. I am grateful for his expertise and guidance throughout this process.

Personal Injury Claim
I was injured in a rear end collision on the Capital beltway. Mr. Rosenthal worked on my case patiently for an extended period of time due to continued medical treatment. He helped negotiate a settlement with the responsible party's insurance company that I would never have been able to accomplish on my own. I liked that we discussed the case as a team, as this allowed me to fully understand a very complicated process. I would highly recommend Mr. Rosenthal's services and I would certainly use him again should the need arise.

What all lawyers should be
Barry has experience to know the law, avoid legal pitfalls, and clearly explains what can and can not be expected for the client. In my long association with Barry I know that he is clear, calm and sharp. When he represented me in my divorce, he outlined a good strategy that worked to my best advantage.

One of the best
Mr. Rosenthal was recommended to me by a former client of his and then I checked out his experience and credentials. What I heard and read did not come close to the high quality of service and advice received during this very complex and sensitive litigation. As a professional, I was impressed with his sincerity, maturity, keen wit, knowledge and wisdom. These traits were everything I could hope for with my representation.

Excellent Research Skills
My case became complicated by Federal vs. state law and Mr Rosenthal navigated these waters seemlessly, efficiently, and with ultimate professionalism. I will forever be grateful for his help in my Estate suit.
Posted by Teresa | January 31, 2015
My divorce took nearly a year. It was frustrating and stressful but Barry made it easy and worry free. I had a great experience and highly recommend him! He told me exactly what to expect, explained procedures, took care of all the paperwork and filing, fought fiercely for my cause and helped me come to terms. I will be using him and his firm for the future. Very trustworthy, honest, didn't hide fees and informed me how much it would all cost. He is very professional and Knowledgeable.

A great lawyer
I've known Barry for more than 20 years. He has represented me and my company throughout the years. He is extremely knowledgeable, responsive, dependable, and professional in his practice. I would recommend him to any of my friends and family members without any hesitation.

Excellent attorney
Barry Rosenthal is a compassionate and intelligent attorney whom I recommend without hesitation. I suffered a serious injury to my shoulder which has lifelong consequences. Without Barry's persistence in representing my long-term needs, as well as his highly effective negotiating style, I believe I may have received little to nothing from the Insurance Company. The company was quite recalcitrant and Barry worked hard to achieve an excellent settlement for me. I am grateful for his efforts on my behalf and am thrilled with the outcome.
