Intro
Jonathan is a seasoned corporate transactions attorney and Partner at Hanson Bridgett LLP, where he has led both the Corporate, Securities & Tax Department and the Sustainable Business Practice Group. With a distinguished track record advising boards and executive teams, Jonathan brings deep expertise in governance, strategic growth, and mission-aligned business models.
He has served on multiple Boards of Directors and was honored as a California Attorney of the Year for his pioneering leadership in drafting and championing California’s benefit corporation legislation—the first legal framework in the U.S. to embed social and environmental accountability into corporate governance. This legislation has since been adopted in 36 states and several countries.
Jonathan advises both for-profit and nonprofit organizations on corporate and other strategic transactions, governance, fiduciary duties, and intellectual property matters. His practice spans entity formation, financing, mergers and acquisitions, commercial contracts and licensing, e-commerce, and technology law, and other business related work. He is also a recognized California Super Lawyer and a trusted advisor to directors and trustees navigating complex legal and strategic decisions.
A passionate advocate for a more just and sustainable economy, Jonathan chaired the legal working group that developed California’s benefit corporation law and helped position Hanson Bridgett as the first law firm to become a certified B Corporation. Under his leadership, the firm earned the Real Leaders Top 100 Impact Companies Award, and Jonathan has been repeatedly named to the MO 100 Top Impact CEO list.
