Before her diagnosis, she began suffering from non-epileptic seizures and relentless vertigo. Triggered by the slightest head movement, sound, or even dim light, it eventually left her bed bound for nearly a year. One day she carefully made her way through the dark onto her apartment floor. There in the quiet darkness, she started painting from her photographs.

Over and over again, she tried to reconcile the photos with the image she saw of herself in the mirror through a series of self-portraits. This continuous hand-eye coordination helped her recover enough to seek out one last specialist - who diagnosed her with severe binocular vision dysfunction.

Now with the aid of specialty tinted prism glasses, Guerriero continues to paint. She holds both a bachelor of arts and a master of business administration degrees from the University of Michigan-Dearborn.
