Sterling Recreation Commission contacted me because they were unable to make changes to their website that was hosted elsewhere. Once we determined that we needed to start from scratch, we jumped in with all kinds of ideas to make it easier on parents to sign their kiddos up for activities. The add-on site and domain for the Sterling Community Wellness Center carries different branding, so we custom coded a header based on the URL that was being displayed.
