Mt. Airy Learning Tree (MALT) is a community service organization founded in 1980 to enrich Mt. Airy and the broader Northwest Philadelphia Community. Starting this week, several classes will be offered on the St. Paul’s Chestnut Hill campus. MALT celebrates the diversity of Northwest Philadelphia, bringing together neighbors to share a wide variety of ideas, information and skills in informal learning environments. Courses that encourage exchange among people of different ages; that reflect the backgrounds, experiences and talents of our community, and that focus on issues of concern to the community are of particular interest. Course catalogs may be found online, or in the Dixon house foyer.
