The Greater Milwaukee Foundation Wednesday announced the winners of its annual civic awards, recognizing leaders who have volunteered extensively or made significant improvements to greater Milwaukee.

The William C. Frye awards honoring volunteer efforts go to Howard Fuller and John and JoEllen Stollenwerk.

Fuller is a former Milwaukee Public Schools chief, a distinguished professor of education and director and founder of the Institute for the Transformation of Learning at Marquette University. He has been a strong advocate of school choice.
