Melvin Waldner

President

Melvin has been in the swine industry for over 30 years. Growing up within the swine industry, he had a vision for creating a feeding system that was built with quality and could meet the demand of the fast changing industry. Over the last 30 years he has seen huge changes within the industry. The need for high quality feeding equipment has moved to the top of the list for meeting the demands of hog producers. The cost of feed has changed the feed product needs. SDI’s feeders meet the needs our producers are looking for in weight gains, quality and durability. Melvin’s vision has carried over to SDI through the last 12 years in building a company that meets the same standards as our feeders. Through Melvin’s vision, we continue to meet the high standards of our producers and to carry that vision of quality, integrity and customer satisfaction throughout SD Industries.
