Client Testimonials

I have observed Mr. Steinfeld as he represented his CEO client in both a civil and criminal Insider Trading action. Consequentially, Mr. Steinfeld was lead counsel in representing my interests in a tangential civil action with the SEC. He has a deep understanding of the law and often sees what others fail to see in its application. He is creative within the foundations and principles of the law and then applies counsel grounded in commercial logic and reason. I have appreciated his care and professional approach in bringing resolution to otherwise challenging situations. He has a great ability to manage the dynamics of conflict with the counterparty without compromise to his client's position and interest. Jeff is a tremendous advocate and is endowed with a unique capacity to see through the noise of a trial, remain focused on what matters, and apply underlying principles and intent of the law in a creative way. The breadth of his legal knowledge and applicable case law adds significant value to his client representation.
