Excellent! I've used Medina Glass for two projects and they have been nothing less than awesome.
A couple years ago I brought them my kitchen cabinets to have some glass put in. They turned out beautiful and for a reasonable price as well.
Now for my most recent experience...
I stopped in a week ago to have some glass put in a cabinet door for my coffee and tea hutch. This woman was so nice and helped me out with every question I had. I also wanted to attach a metal coffee sign on the glass to give it a little more character. She told me the best way to do it but then offered to do it for me. For only $5! I thought that was great customer service and I was very impressed. It turned out awesome and I'll be coming here for all my glass project needs!
