Where can I find a begginers glass blowing class in the Dallas area?

I am absolutely facinated by what some artists are able to achieve with blown glass. I would love to have the chance to learn how to do those things and turn my visions into reality. I live in the Dallas areas, and am looking for any places that offer glass blowing classes so I can compare pricing, location, and what the class has to offer. I do appreciate any advise or information anyone has to offer. Thank you in advance.
