John Doldo Jr., who died Thursday at the age of 93, was a pillar of the community, both in business and in his volunteer service to it. But if building a better community has roots at the neighborhood level, he also excelled there.

“I grew up six houses down from John Doldo on Coffeen Street, right there in the Sand Flats,” said James P. Scordo, retired executive director of Credo Community Center for the Treatment of Addictions.
