Judah Haas is the founder and owner of Alchemy Concrete, the Central Wisconsin concrete contractor that has poured decorative and structural work since 2004. From an Amherst headquarters—and a later Upstate South Carolina shop—he built a full-service firm known for stamped and textured exterior concrete, residential foundations, specialty architectural pours, and concrete pumping. Trade coverage in For Construction Pros has profiled Haas as president on multi-technique patio projects that combine stamped slabs, carved vertical work, and precast details. A 2025 Amherst High School Talon feature traces his path from SPASH graduate and UW–Stevens Point student through earlier businesses MLJ Haas Concrete and Creative Concrete before he took full control of Alchemy around 2010. Haas still presents Alchemy as a family business—his wife Lindsey handles bookkeeping—and keeps Wisconsin and South Carolina phone lines for a two-state footprint unusual among mid-state decorative concrete shops.
