Welcome to our photo gallery of our 20th Anniversary celebration, held at the Ikeda Center in Cambridge on Saturday, September 28, 2013. (Read a story on the event here.) This gallery includes images from the pre-program refreshment period, the two hour program of talks, performance, and discussion, and the post-program reception at the Harvard Faculty Club. Space does not allow for photos of all our guests, staff, and vounteers, but we hope that the images included here convey the spirit of peace and fellowship that defined the day. All photos by Marilyn Humphries.
