Dominic Marshall Principal

Dominic is a serial entrepreneur with a strong foundation in commercial real estate (CRE) energy efficiency and investment. As Principal at RentWise, he leads New Business Development, Investment Sales, Fund Acquisitions, and Leasing—driving strategic growth and delivering measurable value to partners. 

Before RentWise, Dominic built and exited an award winning commercial energy solutions firm operating across DC, MD, PA, NJ, and DE. The firm specialized in brokering commercial natural gas and electricity contracts and executing large-scale energy efficiency retrofits—modernizing over 20 million square feet of CRE assets.  

Projects were structured to maximize incentives through utility rebates, green energy incentives, PJM Interconnection capacity market programs—a program tied to the electric grid serving 13 states and the District of Columbia, and Section 179D federal tax deductions for qualifying energy-efficient installations. 

Dominic combines deep CRE operational insight with energy infrastructure expertise and investment strategy. Known for identifying high-leverage opportunities and executing with discipline, he builds scalable ventures that deliver both impact and strong returns. 

He operates at the intersection of strategy, innovation, and execution—where capital meets performance.
