William (Bill) Hsu is the Managing Shareholder of Oseran Hahn and one of the Pacific Northwest’s leading transactional attorneys.
Bill helps domestic and international clients move through complex business transactions: cross-border deals, business and tax planning, securities offerings, corporate governance, mergers and acquisitions, and real estate acquisition, development, disposition, financing, and leasing. Clients come to him when a transaction has a lot of moving parts and little margin for error.
Born and raised in Taiwan, Bill is fluent in Mandarin and uses that language and cultural fluency to guide a large volume of inbound investment from Asia into the United States. He builds the strategy and the implementation plan for clients’ investment and development projects, from industrial properties and high-rise offices to mixed-use buildings, retail and condominium projects, residential communities, hotels, and restaurants. Before the law he trained in public accounting at Deloitte & Touche, and he reads a deal’s numbers as closely as its contract.
Bill earned his J.D. from Seattle University School of Law, with honors, and an LL.M. from Georgetown University Law Center, with distinction. Earlier in his legal career he practiced at Lane Powell PC, and he has practiced in Washington since 2001. Away from the firm he builds and customizes cars, races his project cars on track days, and coaches youth sports, especially baseball, with his sons.
