Marcy was born in St. Augustine, FL and was raised mainly in the South in a military family. She began painting in oils in 1970 using art instruction books to teach herself the basics. She began art classes in the early 80’s, studying oil painting with Georgia Abood of Alizarin Crimson in Stuart, FL. After moving to Albuquerque, NM in the mid-80s, she attended UNM adult art classes and began painting in acrylics.
Since moving back to Florida in 1995, Marcy studied acrylic painting with Denise Justice in Stuart and decorative art and watercolor in Port St. Lucie. She also studied professional faux finishing in 2006 with Jodi Baldanza at Faux Effects in Vero Beach, FL. In 2010, Marcy studied with Leslie Stokes at Art Mundo for two years, and at that time, began moving into abstract painting.
Marcy maintains a studio in her home and sells her work online. You can follow her on Instagram @marcybrennanart.
