Alan Arthur is one of the busiest developers in town. But Aeon, the nonprofit he leads, isn’t building fancy luxury apartments: It develops, owns, and manages affordable rental units—a market where demand seems only to increase. Arthur has been with the organization for 30 years, when it was called Central Community Housing Trust, and is recognized among the region’s leaders of affordable housing. In 2017, Aeon significantly grew its portfolio by acquiring about 1,200 existing properties to stabilize and preserve as affordable. Today, Aeon serves more than 8,000 residents in approximately 4,000 units.
