Elegant Custom Cabinets
What began in 1947 as a modest woodworking operation in the garage of master cabinetmaker Tom Hammer, has grown into one of the nation’s premier custom cabinet manufacturers - Crystal Cabinet Works. Built on a foundation of craftsmanship, quality, and family values, Crystal has remained true to its roots while expanding into a state-of-the-art manufacturing facility in central Minnesota.
Still proudly owned and operated by the Hammer family, the company is now led by Jeff Hammer and his daughters, who continue to uphold their grandfather’s commitment to excellence. Each cabinet is handcrafted to order, ensuring that every detail, from moulding profiles to door routing and box assembly, is done with precision and care.
Crystal’s success is powered by a dedicated team of skilled artisans, many of whom have spent decades perfecting their craft and mentoring the next generation. Their passion and expertise are evident in every piece they produce, combining timeless design with durability and function.
The garage may have grown, but the philosophy remains unchanged: build every cabinet with pride, one at a time, for customers who value beauty, quality, and true craftsmanship.
