Heather Anne Slayton
Office Administrator
Heather Anne has been an active member of St. Andrew’s Church since 1996, serving in various ministries over the years including the Hospitality Committee, The Flower Guild, The Woman’s Guild, and Christian Education, and her greatest interest lies in Outreach, both Island and afar. In 2008 she formed a small but determined group to offer help to Islanders in need of food, fuel and housing during the economic crisis. Most recently, in addition to her administrative responsibilities, she has been busy re-organizing the church Nursery, a valuable service offered to all members and visitors alike during Sunday worship.  She graduated high school from Stoneleigh Burnham’s School for Girls in Greenfield, Massachusetts, and attended college at Castleton State College in Vermont and the University of Salamanca in Spain. As a girl, she spent summers in Katama with her family. She returned to the Island permanently in 1996 and is dedicated to raising her active two boys, Jack and Wilson. To anyone who asks, she is quick to say, “I love our life here and I love my job.” I wake up in the morning and look forward to the day – I try to remind myself and my boys every day how lucky we are to live in this community and have this church behind us and beside us, every step of the way, through good times and not-so-good times!”

Sara has discovered the WONDER of a VERY popular formation program called GODLY PLAY, and has recently participated in a regional training event to teach Godly Play. Sara also plays for us once a month at our (twice-monthly) 4pm New Worship Service, and has just the greatest spirit!

Caitlin Kane

The NET (Youth Group) Facilitator

Caitlin’s passion and dream is to build a youth group where middle—and high—school age students can gather, serve, learn, mature—and have FUN—in a non-competitive, positive atmosphere—and we are SO glad she’s found The Net! Started by Seven Mainline Protestant denominations on the Vineyard in 2014, The Net is a Christian faith-based, ecumenical group that seeks to draw students from the various island faith traditions to enjoy learning about God and Christ together.
