Highly Recommend!
Working with Tom Dunlap of Dunlap Bennett and Ludwig was a delightful experience. My husband and I needed to do estate planning, but didn't know where to begin. Tom guided us through the process and educated us on the various options and choices we needed to make to address all aspects of our estate planning. He was detail oriented, informative, and answered all our questions in a language we could understand. We would highly recommend Tom; he is knowledgeable, reliable, and trustworthy while still having a sense of humor which made him professionally and personally enjoyable to work with. We were also really impressed with the friendly and helpful support staff at the office in Leesburg, VA.

Excellent Service and Straight Shooter
Tom provided advice on a complex case that we very much wanted to file against another company. His counsel convinced us to approach the case a different way. While the approach was not conventional, it was incredibly effective.

A rare find
Tom Dunlap is a rare find in the legal profession. He is very knowledgeable, tactful and a very skilled attorney. I know that Tom is in high demand, and I can see why. He made me feel like I was his only client. Dedication, personal attention and an ability to explain the technical issues of law made Tom really shine against other attorney's I've worked with. I cannot recommend Tom Dunlap enough! He truly does great work!

Great lawyer for business disputes
Tom was responsive to my questions and very easy to talk to. Unlike the first lawyer I worked with he handled the dispute without having to file a lawsuit and without three attorneys on the same case. Great work!
