Kaore he korero mo nga maatua whanau Vietnamese a Rösler. I whakamanahia ia mai i te whare mokopuna Katorika Roma tata ki Saigon e tetahi tokorua Tiamana e rua ana tamariki koiora, a ka kawea mai ki Düsseldorf, Tiamana ki te Hauauru, i runga i te rererangi o te whakahaere atawhai tamariki a Terre des Hommes i te iwa o nga marama. I whakatipuhia ia e tana papa whakatipu, he rangatira hoia ngaio, i muri i te wehenga o te tokorua i te wha o ona tau. I tipu ake a Rösler i Hamburg, Bückeburg me Hanover, i puta ai ia i te kura tuarua i te tau 1992. Whai muri i tana whakangungu hei kaiawhina whawhai i te Bundeswehr Tiamana (te Federal Defence Force), i whakaaetia a Rösler ki te ako rongoa i te Hanover Medical School. Whai muri i tenei, i haere tonu ia i tana maatauranga i te hohipera Bundeswehr i Hamburg. I whiwhi ia i tana Tohu Paetahi i roto i te pokanga ngakau i te tau 2002. I wehe ia i te ratonga hei Stabsarzt (he taumata mo nga kaitohutohu hauora Tiamana e rite ana ki te rangatira hoia) i te tau 2003.  Pātai: I muri i tana mahi hei kaiāwhina hauora, i haere a Rosler ki hea ki te ako?
