Service

We believe that contributing to our community is the key to being a great neighbor.  We contribute our time, energy, and finances to several great causes, including Habitat for Humanity, local baseball teams, Fisher House, Families of the Wounded, and ASK Childhood Cancer Foundation.  We were honored to donate our skills to survey and certify the world’s largest awareness ribbon for ASK Childhood Cancer Foundation for submission to the Guinness Book of World Records.  We don’t just offer our services, we also give our employees time off to participate in local community service projects.

Did you know, one of our team members participated in all four days of the 2018 Women’s Build, sat on the committee for this event, and helped organize the largest Women’s Build in the Roanoke Valley?  We actively support and are proud to employee veterans.  And we know how to have fun!  Our casino night helped raise over $51,000 for the Fisher House and Families of the Wounded.
