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
