Sandy Seff was always intrigued by the colorful glass bottles on the window sill at her childhood home. After studying abroad in Spain, the enduring beauty of European art glass planted a seed that would bloom later in life.

In 1989, she began pursuing her creative glass. Her inner passion and creativity motivate Sandy to challenge herself artistically and technically in this fascinating media. She passes on her passion and knowledge to her daughter, Kathy, who comments, "I've learned from one of the best! From her technical skills to her fearless attitude towards glass, my mom has an amazing knowledge of and creativity in glass."
