    Leonard is one of the great lawyers from whom I first learned my craft, decades ago. He always demonstrated great understanding of the law, exceptional communications skills both written and oral, perseverance, integrity, character, and excellent strategic thinking. With any kind of complex litigation you would be in good hands with Leonard.
