Our Happy Clients Say It Best
In an industry that serves patients who are often in poor health and prone to illness. Having clean linens on-hand and the ability to process dirty linens is critical in an Assisted Living facility. Since we replaced our older equipment with more efficient Unimac commercial laundry equipment, The Living Center has seen a significant reduction in utility, lined and labor costs. Our laundry room smells cleaner and wash results have improved. Thanks RJ Kool!
