As a Principal in our Jackson, Mississippi office, Trey serves as corporate Marketing Director for PPM and was the recipient of the prestigious Phoenix Award at the 2023 National Brownfield Conference as a “Brownfield Groundbreaker” for his business-minded approach to solving brownfield and economic redevelopment challenges.
