Cooley's Boston office opened in 2007 with a team of 10 partners and since then has grown to more than 70 lawyers. Given New England's strength in incubating and growing future leaders in the technology, life sciences and financial services sectors, Boston was a natural fit for the firm's focus and range of services.

Located in the Back Bay, we provide the Boston market with deep experience in the representation of emerging and publicly-traded technology and life sciences companies. Cooley's leading venture fund practice enables us to meet the full legal needs of the entrepreneurs and emerging companies at the forefront of the New England marketplace.
