Acting has always been Martéz' passion. At the age of 14, being the youngest actor, she starred in a two man play for Gilbert and Sullivan at The Ford Little Theatre, which received rave reviews in the Port Elizabeth newspapers.
Martéz holds a gold medal, with merit, from the London Academy of Music and Dramatic Arts (LAMDA). One of the LAMDA theatre pieces was performed as part of ACT's showcase at On Broadway, Cape Town.
Martéz was selected to attend an Advanced Acting for Film course at ACT Cape Town, which was by invite only and auditions were held to qualify for the workshop.
Having taken to the stage as lead in a ballet production when in junior school, Martéz realised the importance of movement and stillness in a performance at a young age. Martéz' ever growing skill-set includes social horse riding, basic martial arts, swimming and cycling.
