John M. Harrington III

Principal, Sheffield Corporation

A venture capital consultant, consummate networker, and facilitator, John has been active in the field for more than 50 years. During this time, emerging companies have been assisted in raising capital, their business structures have been formulated, their growth has been facilitated, and significant connections to people and resources have been made in the life cycle of their businesses. The industries they have served and the lives of thousands of employees have been materially impacted by many of these companies, with some of them becoming Harvard Business School case studies.

In addition to the numerous companies that have been assisted, civic activities have been actively engaged in by John Harrington for more than 50 years. Participation on school boards, hospital boards, numerous youth sports boards, library search committees, and foundation boards, such as the Winchester Hospital Foundation and the Joslin Diabetes Foundation, has been undertaken.

Involvement in as many as 12 veteran charities, including serving on the Board of Directors of America Salutes You (Guitar Legends for Hero’s, an annual concert where 100% of the funds raised go to support veteran’s mental health charities), has also been a part of John’s contributions.

Assistance and support for numerous ministries and non-profits in the US and overseas to expand their missions and reach have been provided by John as well. For instance, in the last few years, Life Without Limbs has reached over 250 million young people in India.
