In Memoriam

Barbara Safran
Barbara Safran was committed to helping others create a world that her grandchildren and someday her great grandchildren can enjoy. A sustainable Walnut Creek is one step in that endeavor.

Barbara had 8 grandchildren, loves to sing, do photography, and spent time with her family and friends. Barbara’s passion was facilitating others to be the best they can be and through that discovering that she got to be the best she can be as well. She believed that part of being the best we can be was being aware of how we best used our valuable resources.
