Gregory Harrison

Executive Coach

For more than 18 years, Gregory has helped public, private, and nonprofit leaders develop high-performing teams, improve communications and stakeholder engagement, increase self-awareness, and establish new working methods that build trust and foster collaboration. As a leadership coach, facilitator, and consultant, he has worked with executives and teams in various industries, including biotech, government, education, healthcare, and international development and advocacy. Known for his engaging, perceptive, and direct approach, he partners with clients to help them discover positive change, overcome challenges, develop a clear plan to achieve goals, and practice new ways of being. He values curiosity and collaboration and likes to have fun.

Drawing on his diverse background, he brings a deep understanding of organizational and interpersonal dynamics to his coaching engagements. Five years of living in Asia, working with global leaders in dozens of countries across 5 continents, and significant experience in organizational development and change management have informed his approach and perspective.

In recent years, Gregory led significant change efforts in the life sciences sector that contributed to successfully launching a new therapy and reorganizing a critical customer-facing business function. Previously, he served as a member of Oxfam’s global coaching network that supported leaders and mid-career professionals in 70 countries. He worked with executives to successfully implement complex, multi-year, global transformations with broad impact. He has designed and facilitated engaging retreats on topics ranging from strategic planning, change management, and culture enablement.

Gregory is a member of the International Coach Federation (ICF). He serves as a board member for FuelEd and has advised and volunteered for international and local nonprofits.

In his free time, you will find Gregory outdoors and spending time with his wife and two boys. Traveling, bird watching, gardening, fly fishing, and cycling are a few of his favorite pastimes. He lives in Massachusetts.
