“Steelhead was by far the most responsive vendor to our initial inquiry when we started the process of getting our bottling plant up and running. They listened to my needs and came up with a proposal to fit my operation and budget. David came in for a personal presentation and once the sale was completed, the support continued throughout the entire process.”
