Sixtine studied at the University of Denver, USA for a Bachelor of Mass Communications including History of Art and History of Theatre. After graduating, she landed her first job with the Jan Krugier gallery where she became a proficient art dealer before moving to Australia.

Sixtine worked for the Australia Council, Brown’s Mart Community Arts in Darwin, NT where she was responsible for the arts development among the local and Aboriginal Communities. She returned to Melbourne and among other things, Sixtine taught French at the Alliance Française. It is there that she met Ken Armstrong and together they built a futuristic eco tourism facility on Phillip Island. She then completed a Corporate Law degree from the University of Sydney, NSW.

Upon returning to Geneva with her family, Sixtine opted for a career change and was employed as a client relationship manager at Banque Edouard Constant. This period included the introduction of the Euro currency and concerns relating to the Y2k/Millenium potential IT bug. As part of the Bank’s training programme, Sixtine was given the opportunity to study at the Geneva Business School. This was the start of a long relationship that continues with the Geneva Business School.

In 2003, Jan Krugier invited her to become Managing Director of the gallery. It was during a business trip to Moscow to set up an Art show that Sixtine was asked to manage the event and she decided to leave the gallery once again to take on the new challenge. After that, she was involved in the development of ArtbyGeneve, the Moscow and Salzburg World Fine Art Fairs, Art & Jewels Baku, ArtMallorca, as well as the development of two state-of-the-art Freeport facilities in Singapore and Luxembourg.

In August 2020, the Geneva Business School should have celebrated its 25th anniversary. Instead, to embrace the next quarter of a century, Sixtine designed a new MBA specialising in Fine Art International Management (FAIM) whereby art experts and market specialists will share their professional experience with students who can attend courses online or in person in Geneva. The MBA programme will commence in September 2021.
