Meet The Team

Welcome to Greystone Mining - the premier dimensional limestone provider of Door County, Wisconsin and beyond. Owned by Keith, and operated along with his brother Chris, Greystone Mining was established in 2020 with a commitment  to excellent customer service and satisfaction. We are proud to offer the highest quality dimensional limestone products.

Keith, Owner/Operator

A native of North-East Wisconsin, Keith received a Bachelor of Science degree with majors in geology and geography from the University of Wisconsin - Oshkosh. While his geology expertise is applied everyday through his quarry work, he pursues his interest in geography as an avid global traveller, visiting more than 100 countries. Travel highlights include climbing Mt. Kiliminjaro, biking the great hills of Rwanda, exploring the deserts of Saudi Arabia, becoming a PADI certified open-water scuba diver, and walking the Camino de Santiago pilgrimage from Lisbon, Portugal to Santiago de Compostela Spain, a trek of more than 500 miles.


Chris, Sales/Operations

Greystone Mining is proud to welcome Chris to our team. Chris is an experienced, entrepreneurial leader with a long history of success in the industry, having started his own sand business while still in high school and co-owning Griesbach Ready-Mix, giving him an intimate knowledge of the landscape of Northeast Wisconsin. We know you will be in good hands with Chris and will enjoy his spirited sense of humor.
