Plymouth 400, Inc. is a non-profit organization dedicated to commemorating and creating awareness of the 400th anniversary of the voyage of the Mayflower and the founding of Plymouth Colony. Mary Shields is deeply involved with the community in which she resides and is honored to sit on the Executive Board of Plymouth 400.

Shields took on the exciting challenge of designing and developing the Plymouth 400 website. The site is visually compelling, incorporating many images that reflect the beauty and all that there is to see and do in America's Hometown. It informs and encourages communication with the user.
