Just a note to let you all know what fantastic sales & service representative Rick Nehman is for DeVere Chemical!
Denny Devine put me in touch with Rick to firm up a service call to check out our dish machine and general chemical product needs in preparation for our State of Iowa Food Safety Inspection prior to opening. Rick was on time, extremely knowledgeable and took the time to educate us on best practices for the use of chemicals in our restaurant. We very much appreciated Rick’s honesty, skill and professionalism.
