Sandra Power was born in Hull, England. She was educated at the Hull High School of Art and Crafts, where her early passion for art was nurtured. She came to the United States in 1962, married, and took her husband's name of Murphy. She studied drawing and painting with Edmond Archer, at the Corcoran College of Art, Washington DC. Her budding career as an artist took a major detour, following the birth of  twin sons, prompting her focus to shift toward raising a family and pursuing a career as a professional nurse.In 1990 she returned to her maiden name and to her first love; painting. Now, she finds that the richness of her life experience inspires her art both spiritually and creatively.  This is reflected in her skillfully rendered still lifes which express a unique sensibility and engage the viewer on many levels.

Power has won several honors for her art. Her most recent are Oil Painters of America 2012 Best Associate Award and First Place in the Artist's Magazine Still Life competition 2010. For several consecutive years she has won Finalist in the Artist's Magazine annual competitions.

In the summer of 2002, Power moved to Seattle, Washington where she lives near her two sons. She has exhibited in group and solo shows on the East and West Coasts and in England.
