Fenwick & West was founded in 1972 in the heart of Silicon Valley—before “Silicon Valley” existed—by four visionary lawyers who left a top-tier New York law firm to pursue their shared belief that technology would revolutionize the business world and to pioneer the legal work for those technological innovations. In order to be most effective, they decided they needed to move to a location close to primary research and technology development. These four attorneys opened their first office in downtown Palo Alto, and Fenwick became one of the first technology law firms in the world.  MORE >

Michael T. Esquivel

Industry Co-Chair, Digital Health

Partner, Corporate  

Mountain View 650.335.7913


Michael provides strategic counseling to emerging and high-growth companies primarily in the digital health, consumer and enterprise tech, social networking, software and cloud computing industries.

He has a passion for working with cutting edge companies that are changing industries and improving lives. This passion stems from his prior experience as general counsel of a venture-backed healthcare IT company. That inside view provides him with a deep understanding of entrepreneurs and an ability to anticipate his clients’ unique business and legal needs not just for today or tomorrow, but over a company’s entire lifecycle.

An aggressive and tireless advocate for entrepreneurs and the companies and teams they have built, Michael advises clients on all aspects of general corporate and securities law — from formation and corporate governance responsibilities, to equity incentives and employment issues, to intellectual property and commercial transactions. He has negotiated and structured a wide variety of strategic transactions, including seed and venture capital financings, mergers and acquisitions, IPOs, corporate reorganizations and debt financings. He also represents and advises incubators, angel investors, venture capitalists and investment banks.

Extremely active in the growing digital health and healthcare IT industries, Michael serves as an advisor to Rock Health, the sector's leading full-service seed fund. He also regularly contributes to Fenwick's Life Sciences Legal Insights blog where he writes about the latest issues and trends affecting the digital health and mobile health industries.

  • GoPro, maker of the world’s most versatile cameras, in a $200 million acquisition of shares by Foxconn, the world’s largest electronics manufacturing company. Represented GoPro in its IPO.

More About Michael

A high-energy advocate who works tirelessly on behalf of his clients, Michael was recognized as one of the emerging leaders in the legal industry in the Daily Journal’s annual “Top 20 Under 40” for his work advising companies that seek to disrupt traditional healthcare markets and practices.

He was born and raised in Los Angeles and still, deep down, calls it home. His family runs a small food production company there, and, if not an attorney, Michael would be in Southern California working with his brother to support and grow the family business. He’d also like to take a swing at a startup, but bemoans his lack of ability to write code.

When he’s not working, he spends his time trying to get in a bit of exercise and keep up with his three kids, two of whom became black belts in karate by the age of 10.
