David and his team were able to resolve a license/trademark dispute we were dealing with relatively fast and without "breaking the bank". He is a super lawyer in every sense of the word. He quickly grasped the complex issues we were facing and looked at the various options for best outcome. Our case involved a foreign entity, an out of state license infringer and some other complicating circumstances. Hiring his team to “go to bat” for us was the best investment we could have made for the future health of our company. I highly recommend him. He and his very knowledgeable staff get the job done!

President
Mr. Lilenfeld is a "cut to the chase" professional. His advice clearly directed us toward our goals and prevented us from churning fees by tempting diversionary issues. I have used many attorney's over the years and am extremely pleased with our return on investment, the results, and the professionalism of David.
