Born in 1968, Vereeniging.

Buitendach completed her BA in Fine Arts from the University of Pretoria in 1993.

Retha Buitendach's artworks deals with nature in both its macrocosmic and microcosmic detail. The hidden interconnectedness of all living things is an important underlying theme, as is the chance connections between seemingly unrelated things or even words. Unusual and microscopic life-forms as well as those seen every day are sometimes portrayed in unusual contexts, thereby inducing the onlooker to discover them anew. The human figure is seldom directly visible in her artworks, although human presence is often implied. Man is shown to be unique in his ability to experience nature as a supremely beautiful artwork and to be unique in his ability to destroy it all. Her work is both naturalistic and surrealistic, combining the recognisable with what the imagination can add to it.

Her oil paintings hang in many galleries, homes and corporate office throughout South Africa. She also known for her unique use of unconnected wooden objects to recreate natural life forms. By doing this she forces the viewer to rediscover the form they are looking at by using their imagination.
