Adventures in Good Company was founded in 1999 by Marian Marbury. Marian guided for a non-profit called Woodswomen for over a decade before starting AGC. Woodswomen was the first organization to offer a women-in-leadership course that trained women to become guides in the outdoor travel industry. When Woodswoman closed its doors in 1999, Marian wanted to continue offering trips for women based on the same philosophy, which included valuing emotional and physical safety, personal choice and individual goals, healthy relationships with other people and the environment, and valuing women and their way of knowing. Over the next 20 years the company steadily grew, attracting both participants and guides who share this vision of what adventure travel should be.
