Firm Overview

The Rosseau Group is a privately-held investment management firm based in Southern Ontario. We invest proprietary and third-party capital in private market projects in two main categories: real estate and operating companies. While each category contains a wide range of investment opportunities, in our real estate division, we focus on residential and mixed-use development; in operating companies, we seek growth capital opportunities in which we can secure a control position.

Mehlenbacher and Simon S. Mass joined forces with Wall Street veteran Scott K. Moffat to create a firm designed specifically to invest private funds in long term value-oriented projects.
