Morton H. Rosen graduated from New York University Law School in 1962 and is the firm's founder. His practice consisted largely of general real estate law, landlord-tenant litigation, commercial leasing and related litigation until 1976, when he began to represent tenant groups whose buildings were in the process of conversion. Thereafter he specialized in the representation of cooperatives and condominiums. He has litigated cases addressing many of the issues facing cooperatives today, and negotiated on behalf of tenants during the conversion process and in the resolution of shareholder and sponsor disputes. He lectures annually on cooperative and condominium issues at the request of the Council of New York Cooperatives. In addition, he is a member of the Committee on Condominiums and Cooperatives of the New York State Bar Association. Mr. Rosen served as a board member for four years in the Manhattan cooperative in which he resides.
