Arnstein & Lehr is a full-service law firm that serves a diverse client base including large corporations listed on the public stock exchanges, middle-market companies, nonprofit organizations, and emerging businesses. Clients include government, healthcare entities, higher education institutions, financial institutions, trade associations, and a broad range of businesses in the retail, industrial, manufacturing, distribution, technology, and services sectors. The firm also counsels individuals as to their personal needs, including estate planning, probate matters, and the transfer of wealth and business interests from one generation to another. As the dynamics of business, economics, technology, and communications have become increasingly complex, so also has the practice of law become more complex. We believe that the best results are achieved by drawing on our attorneys’ exceptional talents and varied experiences. Attorneys from various practice areas work collaboratively to assist clients in achieving personal and business goals, structuring, negotiating and closing transactions, and handling disputed matters. We aim to become trusted advisors that clients can depend upon to deliver excellent legal counseling. Arnstein & Lehr practices in five main service groups: Business, Litigation, Local Government, Tax and Estate Planning, and Real Estate.
