Miller Manufacturing, Incorporated began operations in 1983. The founders of the company have experience in the dumbwaiter field since 1966. Since our inception we have made steady improvements to the design and performance of the manual dumbwaiter. Our experience has taught us new ways to improve on a proven design. The dumbwaiter was invented by Thomas Jefferson because he had a need to move items form one floor to the next. We want to make Thomas Jefferson's good idea a better product.
