A Faculdade de Medicina do ABC, tamb\u00e9m conhecida como FMABC, \u00e9 uma institui\u00e7\u00e3o de ensino superior localizada no munic\u00edpio de Santo Andr\u00e9, no estado de S\u00e3o Paulo.<\/b><\/span><\/span><\/span><\/p>\n

nstitui\u00e7\u00e3o de ensino que motivou a origem da Funda\u00e7\u00e3o do ABC em 1967, a Faculdade de Medicina do ABC foi oficializada um ano depois, em 1968, e iniciou a primeira turma em Santo Andr\u00e9 em 1969. \u00c9 considerada hoje uma das melhores escolas m\u00e9dicas e de ci\u00eancias da sa\u00fade do Pa\u00eds. Exemplo disso \u00e9 a nota m\u00e1xima 5 obtida em 2011 no Enade (Exame Nacional de Desempenho de Estudantes) nos cursos de Medicina e Ci\u00eancias Farmac\u00eauticas.<\/b><\/span><\/span><\/span><\/p>\n

A faculdade oferece programas que compreendem\u00a0cursos de Gradua\u00e7\u00e3o e P\u00f3s-Gradua\u00e7\u00e3o, para diferentes segmentos dentro da \u00e1rea da sa\u00fade e, da mesma forma, para diferentes n\u00edveis profissionais. Para Gradua\u00e7\u00e3o est\u00e3o dispon\u00edveis os seguintes programas educacionais: Medicina, Ci\u00eancias Farmac\u00eauticas, Enfermagem, Fisioterapia, Gest\u00e3o em Sa\u00fade Ambiental, Nutri\u00e7\u00e3o, Terapia Ocupacional<\/b><\/span><\/span><\/span><\/p>\n
