First we offer a comprehensive listing of products. Our customers realize there is no reason to consider multiple vendors when DSI provides these products under one roof direct from the manufacturer at a very competitive price.The second way DSI stands out is via the "value-added services" we provide from sales to customer care. Our sales staff is well trained and experienced. We spend many hours ensuring what we quote and deliver meets our customer's unique needs. We are responsive. Quotes are delivered in less than 24 hours. If there are CAD drawings or architectural layouts involved quotes will still be ready in about two business days. DSI crews will assemble and install everything we sell. Standard products ship in less than 10 days from order date. Our billing and support are backed by state of the art technology and folks that know the products we sell and the needs of our customers.
