About Us

 Jack and Diane Martellaro established their family-owned and operated business, Martellaro Marble and Granite, at the turn of the 21st century.  Being a union bricklayer and stonemason for over 20 years, Jack has rock in his blood! Growing up in the Hermann, Missouri area, Diane – a music therapist by trade – shares her creative talents as well as her husband’s passion for granite, marble and other natural stones. A large amount of granite and marble slabs are quarried in Italy, which also happens to be the birthplace of the Martellaro name!
