Sales Calls

Office hours are from 8:00 a.m. to 5:00 p.m., Monday through Friday.  To conserve time and ensure you adequate attention, we urge you to make a definite appointment before coming to the Purchasing and Materials Services Division.  Routine “courtesy” visits are not encouraged as they can disrupt the daily workflow.
