Our Leadership Advisory Board

Alan Lewis

Alan Lewis co-founded Pinnacle LTD in 1992 to create positive social change through leadership and team development for both for-profit and nonprofit organizations.

As Chairman of Grand Circle Corporation, Alan shapes the company’s vision and direction. Over the last 30 years, he has transformed Grand Circle from a $23 million-travel company that was losing $2 million a year when he and his wife Harriet acquired it in 1985 into a global enterprise with gross sales of $600 million in 2014. The company’s reach has expanded from one office in Boston—now its worldwide headquarters—to 42 offices on six continents.

Alan and Harriet also established the Grand Circle Foundation to support the communities in which Grand Circle works and travels, including some 300 humanitarian, cultural, and educational endeavors worldwide, including 100 schools, in 50 countries. Grand Circle Foundation is an entity of the Lewis Family Foundation, which has pledged or donated more than $130 million since 1981. Committed to hands-on philanthropy and volunteerism, Alan and Harriet founded a community service program for Grand Circle associates through which more than 90% of them give back to their community each year. In the last 21 years, the Foundation’s Community Service Team, led by Grand Circle associates, has donated more than 100,000 hours of service to local non-profits worldwide.

The Foundation has received several honors, including Travel + Leisure’s Global Vision Awards for philanthropy in 2013 and 2010, the Hero of Philanthropy Award from the National Society of Fundraising Executives, designation as the first member of the UNESCO World Heritage Centre Partners in Conservation, and ongoing recognition as one of the top 50 charitable contributors by the Boston Business Journal.

In addition, Lewis has been personally recognized for his philanthropic leadership, including the Committee to Encourage Corporate Philanthropy’s Excellence Award for CEO leadership and innovation in philanthropy and Ernst & Young’s New England “Social Entrepreneur of the Year.”

Whether through his business or philanthropic work, his mission has always been the same: to do all that he can to help change people’s lives.

Harriet Lewis

Harriet Lewis, Chair of the Lewis Family Foundation, is an educator, philanthropist and world traveler. She is passionate about helping guide social change and developing gutsy leaders – with a special focus on women and youths. Early in her career, Harriet worked with children facing many challenges. From this experience, she developed a strong belief that the world’s our best hope for deep and lasting com­munity transformation rests with our young people.

Harriet founded the Next Generation Leaders, a program to provide rising college freshmen from Boston’s Dorchester, Roxbury and Mattapan with work, service and international travel opportunities to advance their leadership and improve their chances of suc­cess in life and college. Harriet brings an educator’s compassion and skills to the Lewis Family Founda­tion, ensuring that we “ask and listen” to the young people, their families, and leaders who live in the neighborhoods and global villages where we work.

Harriet was one of the original founders of Pinnacle, along with her husband Alan and Bob Weiler. She was instrumental in positioning Pinnacle as the gate for the LFF philanthropy. Observing that most nonprofits don’t take the time to get away to take a hard look at their operations and hot issues, she knew Pinnacle would be an invaluable asset to these organizations. To ensure their support was going to strong leaders and teams, LFF requires attending Pinnacle Leadership training as one of the conditions for funding.

Harriet is at home outdoors, all around the world, and tends to her garden with the passion and pur­pose she brings to her philanthropic work
