About Siemonsma Construction
Building Excellence, One Home at a Time
South Dakota native, Ralph Siemonsma, began his construction career in Florida in 1973 working with his father-in-law. Ralph graduated from Allstate Construction College and obtained his Florida General Contractors License which he has continued to hold. In 1990 Ralph returned to South Dakota with his wife, Debbie and their three children. The move to Spearfish continued Ralph's desire to turn dreams into homes with quality craftsmanship and attention to every detail. Ralph's son Jarod joined him in the family business in 2000.
