Harold Nathan believes that listening is as important as advising in order to meet a client’s objectives as completely and efficiently as possible. Harold counsels clients regarding mergers and acquisitions, joint ventures, contracts, and banking and finance. He draws on the support of firm resources and practice groups to address a wide range of matters of concern to his clients, including taxation, intellectual property licensing, real estate and employment.

Harold began his commercial law practice in Japan and over the years he has continued to represent many clients based in Japan and elsewhere in Asia. Harold also acts for U.S.-based commercial and financial institutions, including insurance companies and community banks. In his representation, he applies his knowledge and experience to a matter by first appreciating and considering the context in which it arises, rather than approaching it from a narrow or entirely specialized perspective.
