Meet the Attorneys


I contacted Mr. Sewell because I had a product idea that I was looking to develop, patent, and eventually manufacture. My main objectives were finding out if the idea had already been patented and, if not, what steps I would need to take. He fortunately took a ‘hands-on’ approach and walked me through my concerns and questions without fail.

Joseph C., New York

I received lawsuit papers in the mail for a case in New York. At the time, I no longer lived in New York and didn’t know what to do. Subsequently, I spoke with Dayrel and literally asked him “to make this case go away”. Lo and behold, that’s exactly what he made happen for me! His communication with me was excellent and his robust advocacy on my behalf was exactly what anyone should look for in legal representation. Mr. Sewell is very good at what he does and he greatly helped me in my dire time of need. For that, I will always be grateful for his services and professionalism.

Isaac S., Texas

Over the years, I have known and worked with Mr. Sewell. He has provided me with outstanding advice and guidance. I have found him to be a particularly helpful guide in navigating the complexities of civil litigation. He has a particular ability to boil down the law so that it makes sense. The confidence that he has given me leads me to give him my highest recommendation. It’s always refreshing to deal with an attorney who is so clear and direct.

Robert F., California

We employed Mr. Sewell's services to obtain federal trademark registration for one of our artists, Whyteout. The trademark was successfully obtained in a timely and cost effective manner. We also appreciated the advice he provided to us when we had to make category decisions. Our questions were always addressed and he conducted himself in a professional manner throughout the entire process. We intend to utilize his services in the future.
