 Layton Engage. Find your focus. Marlis Winkles talks about cornerstone cabinets and countertops. From the moment my husband and I stepped into their room, we were warmly welcomed, and I knew I wanted to work with Bonnie and Lisa to make my dream kitchen a reality. They made helpful suggestions, and Bonnie even came to my house, which was amazing to me, to see the furniture pieces I wanted to incorporate in my design. So I couldn't be more satisfied, and I would tell anybody to choose cornerstone cabinets to do their kitchen.
