Biography

Chris McGuire is the Ocean Program Director for The Nature Conservancy in Massachusetts. He shapes marine priorities at the state level while harnessing TNC's global experience and scientific expertise to develop innovative conservation solutions. Chris is focused on conserving Massachusetts' critical marine and coastal systems by developing market incentives to encourage more sustainable fishing through partnerships with commercial fishermen; advancing conservation positive ocean planning efforts; and using natural solutions to reduce the risks of climate change.

Chris leads monitoring projects in the New England groundfish fishery and has been the principal investigator on collaborative research projects focused on iconic New England species like Atlantic cod and halibut. Chris serves on state, regional and federal advisory committees and working groups, and regularly presents his work at national and international workshops and conferences. In fall 2023, he was elected Chair of the Stellwagen Bank National Marine Sanctuary Advisory Council.

As a child, he spent many rainy childhood days at the Nantucket Whaling Museum, learning about the industry that led to one of the first species population crashes due to overfishing. Now Chris is working with New England fishermen and innovative technology to help return fish stocks to sustainable levels.

Before joining TNC in 2011 he was a faculty member and Captain aboard oceanographic research vessels at Sea Education Association for more than a decade. Chris has a B.A. from Connecticut College, holds a 1600 Ton USCG Ocean Master’s License, and earned a Master of Marine Affairs from the University of Rhode Island.

When not pursuing marine conservation initiatives Chris can often be found out on the waters around Woods Hole or working on home improvement projects with his kids.
