Petro matriculated at Brits High School. Petro obtained her higher diploma with honours at the Teacher's College of Education in Pretoria.
In 1991 her life time love for ART eventually resulted in her enrolling at Pieter Millard Art School. Her love for art led her further a field when she participated in a Sculpturing course with Charles Gothard. The two mediums complimented one another perfectly and further entrenched her talent as an artist. She also did an advanced course in painting with Mimi van der Merwe. Currently she is engaged in "Old Masters" painting techniques with Elizabeth Riding.
Petro is an impressionist and although her subjects are diverse, she has a passion for flowers and children. Her work is colourful, bold, fresh and unique. She paints in oils and acrylics.
She has fulfilled many commissions, including one for the Ambassador of Algeria. Her paintings have travelled to Japan, England, Europe, Canada and Australia.
Being a devout Christian, Petro believes that God has a purpose for her as an artist, and instills the belief that her paintings will be a blessing to whoever owns them, wherever they may be displayed.
