As businesses grow, they often face new challenges and issues. They outgrow their existing capacity, their business and lending relationships, and organizational structures. We help them through all phases of a business life cycle—from formation, through expansion, acquisitions and beyond.

William M. Umbach advises businesses on a full range of legal matters, including commercial transactions, mergers and acquisitions, entity formation, governance, restructuring, business planning, corporate divisions, recapitalizations and divestitures. With advanced training in taxation, he is able to help his clients organize, manage and reorganize their businesses to adapt to the changing business climate and to structure transactions in a tax-advantageous manner. Will also advises on lending transactions, including setting up new entities and representing borrowers when financing and refinancing credit facilities.

Will has advised clients in a variety of industries, including textiles, marine and other types of manufacturing, automobile and boat dealerships, and health care entities of various types, including large physician medical practices and hospital trust services companies. His clients range in size from individuals navigating local markets to Fortune 100 companies with more than $1 billion in annual revenue, and he currently serves as outside general counsel for a leading manufacturer with locations in four U.S. states, China and India, as well as other companies in the manufacturing, fitness amenities and appraisal services industries.

I enjoy helping clients navigate the law as necessary to best achieve their business goals. Sometimes a client has complex issues, and I enjoy doing complex deals, but my goal is always to achieve those goals in the most straightforward and cost-effective way possible.
