Andrea Petitto was born in rural Massachusetts. Her father had been a sculptor and Andrea grew up making things with modeling clay. As a small child Andrea was fascinated by the images in large folio books of Rodin and Michelangelo sculptures and these influences can still be seen in the strong sense of solidity and form in her paintings. In 1990, after a career as university professor and industry consultant, she moved to art.
Around the turn of the century Andrea devoted herself to the study of painting and became a full-time artist with a particular passion for the human figure. She also became an avid amateur dog trainer and handler. Andrea has combined her love of dogs and other animals with her interest in figural art leading to many paintings of her own dogs as well as others she encounters on the beaches of Cape Cod.
