7Sisters LLC was formed as an international advisory firm in 2011 with the primary purpose of helping U.S. companies broaden global business relationships in a world with increasing demand for adaptability.

My own traditional business acumen was inspired by generations of great business leaders whom I have had the privilege to know. Among them, my own grandfather and great mentor, Forrester (Tim) Clark, was the CEO of HC Wainwright & Co, where I built the foundation of my business career.  My step-grandfather, Benjamin Brewster Jennings, Chairman of Socony, was one of the legendary Seven Sisters of the oil industry and one of the 4 partners to form ARAMCO (now by far the biggest energy company in the world).   This  great legacy of partnership is a symbol of our commitment to foster lasting global relationships.

7Sisters LLC has a broad and deep set of relationships with CEOs and family business enterprises from around the world.  We believe in bringing our clients and relationships together to share knowledge, and build bridges for cooperation. 

7Sisters LLC has led numerous investment forums, special briefings and global leadership retreats.

The 7Sisters LLC team is committed to building lasting strategic relationships between U.S. companies and global partners. We invite you to actively collaborate with us.
