Coding, Not Just for the Boys

Instead of scheduling brunch plans or enjoying a lazy afternoon this weekend, close to 40 women took over the Sunlight conference room this past Saturday for an all-female software training program conducted by GeekChic.

If you are interested in partnering with Sunlight to host technology workshops, please contact
