In Loving Memory of Mark Wadman: The Granite Twin Who Touched Countless Lives

Cornerstone Marble & Granite's founders, the Wadman twins, Mark and Matt, have left an indelible mark on the world of marble, granite, and quartz fabrication and installation. Born on the same auspicious day, their lives were intertwined from the very beginning. For over 35 years, they embarked on a journey together, crafting a legacy that will forever be etched in stone.

Straight out of high school, these two talented brothers ventured into the world of stone craftsmanship with unwavering determination. They honed their skills in the picturesque landscapes of Sarasota, Florida, where they meticulously learned the art of slab fabrication and installation by hand. Their dedication knew no bounds, as they tirelessly worked on commercial buildings, beautifying both interior and exterior spaces with their craftsmanship.

In the early 90s, the brothers decided to return to their roots in the Indianapolis area, carrying with them a wealth of experience and a passion for their craft. They continued to shine in the industry, lending their talents to various companies and projects. However, it was in 2004 that they truly found their calling, when the Wadman twins founded Cornerstone Marble & Granite.

With an unmatched lifetime of experience and an unyielding commitment to quality, the Wadman brothers quickly made a name for themselves. Their expertise in granite, in particular, elevated them to prominence, earning them the affectionate title of "The Granite Twins." Their journey reached a significant milestone in June 2006, when they proudly opened their showroom in Greenfield, Indiana, providing a space where clients could witness firsthand the beauty and elegance of their creations.

Yet, life's journey took an unexpected turn, and in 2022, we bid farewell to the visionary leader, Mark Wadman. His passing left a void in the hearts of those who knew him and those who had the privilege of witnessing the awe-inspiring works of art he and his twin brother brought into existence. His passion, talent, and kind spirit will forever be cherished by all whose lives he touched.

As we remember Mark Wadman and the beautiful legacy he co-crafted with his beloved brother, Matt, we celebrate the enduring impact they have made on the world of stone craftsmanship. Their dedication to excellence and unwavering commitment to their craft will continue to inspire generations to come. May their story stand as a testament to the power of dedication, passion, and brotherhood.
