Client Testimonials

I would trust Mr. Kelly with any litigation matter that might come my way.

I was involved in a very complex legal matter with multiple parties in a multi-state litigation. Mr. Dennis Kelly was lead council for my case and he developed and synchronized the legal plans between the various attorneys I had to retain. His ability to coordinate and communicate with everyone was sensational. Mr. Kelly provided outstanding legal services and was always very easy to communicate with. He and his team were simply remarkable throughout the entire process. I was very happy with the services provided as well as the outcome of my case. Mr. Kelly is a gifted attorney who is very talented. I would recommend him to anyone who needs legal representation in a civil court matter.

Mr. Kelly is a consummate professional. He is thorough in his approach, and unusually objective and clear about his analysis. Although not always perceived as positive by the client, Denny does not assume he is in the "right," but wants to know reality. He has significant experience to bring to bear on behalf of his clients; his counsel is thoughtful, thorough, and, most importantly, without an ego. All said, he is a great advocate.
