How hot does it get in degrees F. Are you losing any coolant? If you lose it internally won't be any external leaks. Can you check for combustion gases in the coolant?

Does the radiator fan/s work?

Just to add, as far as overheating, you intake manifold gasket among common repairs, is second only to the thermostat as far as replacement.

Did the shop do a cooling system pressure test?

If your losing coolant and it isn't external, I'd have to check that gasket I mentioned.
