Petro began her career as an artist in 1993 after discovering by chance that she was a highly talented painter. Each year Petro would challenge herself to learn something new by completing a course and it was in this time that she saw an ad for an upcoming art course being offered in Muizenberg. After enrolling, her art teacher was astonished to discover that Petro had never had any previous training and had in fact never drawn or painted before. After only a few lessons, Petro dropped out of the class and launched her career, becoming the confident artist she is now. Charcoal was her first medium of choice and later she moved on to oil paint
Petro adopted her artistic name from a young lioness named “Shingalana” which she painted early on in her career. A highlight in Petro’s interesting career is undoubtedly her use of colour therapy while teaching art to trauma patients and prisoners, who, with her help, were rehabilitated. Owning her own art gallery in Tulbagh was also a special time, which she hopes to recreate in the near future when she opens something similar here in Gansbaai.
