Over the course of the last 20 years, SDI-TDI-ERDI has enjoyed success while being forerunners in the industry with groundbreaking ideas while staying honest in our business tactics and ethical with our approaches to drive new business towards us. However, the number one attraction that our group of organizations has is NOT the lower prices or the modern up-to-date materials. It is the customer service level that takes care of our customers’ needs. It is the other person on the line listening to our members’ situation and trying to work with them, side by side in making it better. It is about the people running the business wishing the utmost success on their customers and dealers so we can, in turn, share that success as well. We are a family, and we want to invite you to take a look at our Family Scrapbook.
