Tessy has been appointed Global Advocate for Young Women and Adolescent Girls at UNAIDS in 2015. Since then, she was able to travel for UNAIDS on a mandate to raise awareness of HIV/AIDS among young women and adolescent girls by attending lectures, speak to key stakeholders, and go and visit organisations on the ground. She has been working closely with the Princess of Swaziland and Prince Africa Zulu. Both of these young people are also very engaged in raising awareness of HIV/AIDS in their regions and form a great team of young advocates to address the HIV/Aids epidemic.
Moreover, She had the great honour to work on several occasions with HRH Prince Harry who is also a great advocate for this cause.
She has been involved for years now with NAZ, a HIV/AIDS advocacy organisation that organises the NOSCARS to honour game changers living with HIV/AIDS. http://www.thenoscars.com/
