To maintain our commitment to excellence, we have invested extensively into our personnel, machinery & equipment, front & and back-end systems, our facility, R&D and now, most recently, our newly designed mobile friendly website, www.mdisupply.com. These investments have made MDI a favorite among our customers.
Professional service, quality and reliability are the components and commitment that make up the foundation that MDI® is built on.
