This “Best of Nonprofit Spark” show features three of my favorite guests from the past 25 episodes who are hands-on leaders. The first guest is Alicia Hansen of Salt, a new nonprofit based in New York City. The second guest is Gibson Fay-Lablanc of The Telling Room, a five-year-old organization based in Portland, Maine. The final guest is Whitney Smith of Girls for a Change, a 10-year-old nonprofit based in San Jose, California. Taken together, the interviews demonstrate a common progression in how nonprofits grow and build over time. Alicia, Gibson and Whitney are energetic, inspiring leaders and it was a delight to have them on the show.
