Raheem David (left), Stefanie Seldin (center), and Quentin Watts pause for a breather while remodeling a home in West Philadelphia last month for Rebuilding Together Philadelphia, which revitalizes communities by transforming vulnerable, owner-occupied houses into safe, energy-efficient homes at no cost to homeowners in order to improve the health and safety of the residents. Seldin is president & CEO of the nonprofit, while David and Watts, both carpenters, volunteered their services for the day.
