"It is not very often that people ask me what it is that inspired my paintings. I find this question to be very thoughtful and inspiring for my paintings in the future. Growing up in Italy I was surrounded by ports with beautiful boats constantly coming and going. My father and I would often go down to the harbors to look at all of the different boats there. It was at that time that I developed my love of boats, and wanted to capture their beauty on canvas.

"I am very fortunate to be able to make a living as a professional artist painting the very subject that I loved as a child, and continue to love as an adult. It inspires me as an artist to know that my paintings are appreciated by the people who see them in the galleries and take them home to share their beauty."

D'Alessandro retired from painting after severe bouts with Lyme's Disease which left her with extreme pain in her joints and has since kept her from her painting studio. D'Alessandro was married to the late artist Luiz Coelho.
