Who We Are Contact

Our Mission

Acquire quality underperforming properties, enhance value through repositioning and select capital improvements, remain vigilant in our oversight, and sell at the opportune time to maximize returns to our investment partners.


ROC Inc. is a real estate development firm with headquarters near Chicago, Illinois. We have been around since the mid-1990s building a track record of excellence in the real estate industry. Our reputation precedes us in the greater Chicago area regarding commercial property enhancement through redevelopment and management.


ROC Inc. focuses on properties which can be acquired at a discount to replacement cost and offer growth opportunities. By repositioning and extracting value from existing properties we compress the “at-risk” timeline and accelerate cash flow, compared to ground-up development. Our approach fosters measurable appreciation, with shorter investment horizons, less-speculative profit margins and lower risk than traditional real estate development.


ROC, Inc self-performs and concentrates on redevelopment and adaptive reuse of existing properties. We currently are focused on expanding our self-storage holdings and selectively adding industrial properties to our portfolio.
