What else will you get from TGS?
  • Invaluable experience. We've moved grain five days a week, 52 weeks a year, for nearly a decade. We've encountered every possible situation—often more than once. You can be confident we'll know how to tackle whatever your job presents.
  • Positive attitude. Grain vaccing is an extremely tough job, but TGS's approach makes it enjoyable. Our strong, young crews are well-trained and eager to work hard. They get a rush out of moving 50,000 bushels in a day—and we bet you will, too!
  • Family commitment. Thompson Grain Service is a family-owned company. We stand behind our services, and we're personally invested in your satisfaction. And like you, we're in it for the long haul.
