McDonald® Customer Service: 800.292.2737 View Brand Website

At A.Y. McDonald Mfg. Co, we know that there is only one boss and it is the customer. The customer is the person that pays everyone’s salary and who decides whether a business is going to succeed or fail. The customer doesn’t care if a business has been around over 164 years….the minute it starts treating him badly, he’ll put it out of business simply by spending his money someplace else.
