Paul D’Alessio, a graduate of the University of Arizona’s Landscape Architecture program founded Kalamazoo Materials, Inc. in 1985 after discovering a supply of decomposed granite above the Kalamazoo copper ore body in San Manuel, Arizona, thus providing Kalamazoo Materials its name and its first color, Wildcat Red. Since then we have expanded to several locations throughout Arizona and Nevada. Popular products such as Apache Brown®, Mohave Gold®, Palomino Coral®, Rebel Red® and more have become common industry standards in multiple gradations ranging from 2MM minus to large showpiece boulders.

Our years of experience as innovators and designers in the landscape construction industry have taught us that landscape rock is not “just rock,” it is a cost-effective, eco-friendly material that when artistically combined can beautify and preserve any project. Kalamazoo Materials chooses to ONLY mine and sell quality-tested granites, rhyolites and quartzite that can be found in abundant reserves to keep our services and color outstandingly consistent for our clients. Our multiple locations supply areas throughout Arizona, Southern Nevada, Southern California, Utah and anywhere freight can be arranged.


These products are guaranteed to be durable, preventing the weathering, melting and decomposition commonly associated with other rock products. Our multiple locations ensure that the materials you select for your project will be readily available for touch-ups and new construction, undoubtedly withstanding the test of time.
