Countess Bettina Bernadotte of Wisborg, born 1974 in Scherzingen, Switzerland, is the oldest daughter of Countess Sonja and Count Lennart Bernadotte. Following her degree in Business Administration in Tourism: Destination Management at the University of Cooperative Education in Ravensburg and work as an independent corporate consultant for companies in the tourism industry, she prepared to assume direction of the Mainau GmbH company by serving as Personal Assistant to her mother and as Authorized Signatory from 2002 to 2006.

Countess Bettina Bernadotte assumed leadership of Mainau GmbH in 2007, with the goal of leading the family business into a successful future with secure jobs in both tourism and the new segments of Quality Management and Continuing Education. Yet another important issue for Countess Bettina is Mainau's continuous pursuit to maintain the values outlined in the “Grüne Charta” (Green Charter), which promotes respect for nature and its preservation. She also seeks to make a meaningful contribution toward encouraging those who visit or encounter the Isle of Mainau in some way to slow down from the stress of everyday life and to simplify their lives.

Since October 2008, Countess Bettina Bernadotte is President of the Council for the Lindau Nobel Laureate Meetings and member of the Board of the Foundation Lindau Nobel Laureate Meetings. She has been a member of the Council since 2005.
