MARION — During a special presentation at the Thrillbillies’ final home game of the season, the Black Diamond Family of Businesses formally announced that Integrity Roofing and Exteriors has secured the signature naming rights to the dome at the 94-acre, $40 million Oasis Sports Complex in Marion.

The Dome, a climate-controlled, multi-use indoor facility capable of hosting soccer, baseball, basketball, volleyball, and more, will now be officially known as The Integrity Dome.
“This partnership is a natural extension of our company’s mission,” said Terry Gwaltney, CEO of Integrity Roofing and Exteriors. “At Integrity, we’ve always believed in protecting what matters most, and that includes investing in the health, growth, and well-being of the communities we serve. We’re proud to be part of something that will bring opportunity and energy to Southern Illinois for generations to come.”
The Integrity Dome is a cornerstone of the Oasis Sports Complex, a first-of-its-kind facility designed to elevate Southern Illinois as a destination for youth and amateur sports tourism. The dome itself will feature full-sized indoor turf fields, convertible courts, and a full-service restaurant and bar with sightlines to as many as 18 live games happening throughout the complex.
“This is exactly the kind of partnership we envisioned when we set out to build Thrillville,” said Rodney Cabaness, co-founder of Black Diamond Harley-Davidson and a lead developer behind the Oasis Sports Complex. “Mutually beneficial marketing relationships with incredible corporate citizens like Integrity Roofing make projects like this possible. Together, we’re helping
Southern Illinois realize its full potential, not just in sports, but in economic growth and regional pride.”
The Oasis Sports Complex is made possible through support from the City of Marion, Williamson County, and private partners. The Integrity Dome is expected to serve as a year-round hub for both local athletes and traveling tournaments, with a projected impact on tourism, hospitality, and small business across the region.
