Sam is a business lawyer, serving as general counsel and advisor to businesses in the pharmaceutical, biotech and specialty pharmaceutical, medical device and software industries. His clients are focused on rapid growth through highly incentivized and educated workforces and focused business plans. He generally counsels clients developing valuable proprietary assets and a strong brand name, with an emphasis on near- to medium-term exit strategy, or an acquisitive/accretive strategy for growth. Sam works with public companies in sophisticated transactional matters, prominent universities and hospitals in commercializing intellectual property, newly formed corporations in a general counsel capacity, and private equity and venture investors worldwide.

Sam has extensive experience with venture capital financings, licensing and partnership agreements, mergers and acquisitions, and joint ventures. He frequently works with companies doing business in India, China, Canada and many other jurisdictions worldwide.

Sam’s greatest pleasures are gardening and cooking with his wife and three children. He considers himself a wanderluster and likes to immerse himself in the literature and history of the places he visits. Sam has a deep appreciation for the arts and has been involved in the founding and growth of two innovative musical institutions – the Boston Modern Orchestra Project, Inc. (BMOP) and Odyssey Opera. Despite his involvement in the classical music scene, Sam professes absolutely no musical talent of his own. He is also active in the class and alumni associations of his alma maters, especially Amherst College.

Prior to law school, Sam served as deputy director for the Massachusetts Democratic Party and as a campaign manager for then-state senator (and later Congressman) John W. Olver, who at one time was the only member of the House of Representatives with a PhD in the sciences. Sam retains a keen interest and involvement in politics, policy and diplomacy. As a survivor of stage 4 non-Hodgkins lymphoma , Sam supports several cancer research organizations.
