"Purchased a Christmas gift for my dad and the quality is to notch!!!  I'm beyond happy with  my product! Highly recommend if you are looking for something custom or local! 5 gold stars, Lesa Cafferty!! :) *****"

"I am doing my PhD in chemistry at u of manitoba and know Lesa for almost  5 years. In a word, she is great in her job and gets you what you  exactly want. "

"I spent 6 years in grad school at U of M and used Lesa's services regularly.  I always got exactly what I wanted no matter how unusual or demanding my designs were.  When I moved to MIT to do my postdoc, I wasn't able to find anyone in the area (that includes Harvard and BU as well) who was as good as her, and so I outsourced projects to Lesa and had them shipped all the way to me.  She's a perfectionist and always gets you what you want."

" Very talented scientific glassblower with 20 plus years of experience!! Great customer service also!!!!!"

" Top notch problem solver.  Can make anything out of glass! Great glass blower to know in that region."
