Kerry Mullen joined the church in October 1998, along with her wife Deb Hardy. Both are talented musicians, with Deb being one of Cape Ann's best guitarists and singer-songwriters. Kerry is an artist by trade and is currently focused on sculptures made with clay, cement and glass. She is a graduate of the Massachusetts College of Art.

Kerry grew up in Waltham and has lived in Gloucester since 1994. She served as Building and Grounds Chairperson before coming on board as Sexton in October of 2007, upon the retirement of Lucille LePage. Kerry says she experiences grace in the simple, physical, day to day work of caring for "this old house".
