Justin Mann


Justin brings to the company a BA from Saginaw Valley State University, where he studied business. Sharing the same vision as his dad, he strives to bring only quality workmanship and products to Cornerstone's customers. Justin loves the outdoors and enjoys working with the crew in rough and finish carpentry. He is also invested in the youth of his community: Justin coaches several sports and has a lifelong passion for football. He and his wife, Angela, stay busy enjoying life with their three active boys.

"Justin and his father have always had the vision of building quality homes using only quality materials that meet or exceed standard building practices."
