A Metro East real estate expert with a public-service backbone.
Pat McMahan is the Broker/Owner of McMahan Realty Group and the former Mayor of Mascoutah, Illinois. Fourteen-plus years of local government leadership shaped a real estate practice built on transparency, accountability, and an obsessive knowledge of the Metro East.

Built here. For here.
Pat's roots in the Metro East run deep. As Mayor of Mascoutah, he led the city through more than a decade of growth — managing budgets, infrastructure, and the kind of long-horizon decisions that shape communities. That same standard of care is what clients of McMahan Realty Group experience on every transaction.
Today, Pat works directly with buyers and sellers across Edwardsville, Glen Carbon, Collinsville, O'Fallon, Belleville, and his hometown of Mascoutah. No call centers. No handoffs. Just a broker who picks up the phone and knows the streets you're house-hunting on.
Community involvement isn't a tagline — it's the foundation. Pat continues to be active in local civic and business organizations across the Metro East, because the same network that built his public-service career builds better outcomes for his clients.
