If you are a MA plumber or gasfitter and you are interested in getting your NH license, I highly suggest this school. I came here and was very impressed from my first phone call to my last test.

- Jonah Lopez
I've been attending GSTS for a decade or so, and cannot imagine a better trade specific instructor. Jim is extremely knowledgable, shares the info with enthusiasm and relates the material through real world stories. The facility is full of hands on equipment, and his manner as an instructor (and gentleman) is an A+. 5 star
