“Having worked with STONE on a couple of projects I can say that Mary Sharrett and her staff work diligently to complete projects on time and in a highly professional manner. They are trusted by state and federal agencies and their experience with permits saves the client time. They are among the best and I look forward to working with them again in the future.”
