Marcia is known for her tongue-in-cheek vignettes of her personal life and the lives of her family and friends. Nearly all of her paintings are interiors because of her deep and abiding horror of "the outdoors."

Marcia majored in Painting at Montserrat College of Art where she now resides. Her exhibitions include the Wenham Museum, Wenham; Acacia Gallery, Gloucester; Visual Art Gallery, Newbury Street, Boston; Mingo Gallery, Beverly; the Firehouse Center, Newburyport; Brush Gallery, Lowell; and the Bromfield Gallery, Boston. An award-winning painter, she is currently represented by Chameleon in Newburyport.
