Ann’s walk with The Lord began in Sunday School when she accepted Jesus as her Savior at age eight. Her growth as a Christian had its stops and starts based on whether she was connected to a church with a Gospel based ministry. When a Church she attended for two decades drifted away from its focus on The Gospel, Ann knew she had to leave. The Lord led Ann to WEC in 2011 and after that very first Sunday, Ann knew she had found her spiritual home. In the ten years that Ann has been a member at WEC, she served in the following ministries; Sunday School, VBS, Hospitality, Bible Study, Prayer Group, Community Group, and Deaconate. Ann attributes her continuing spiritual growth as a Christian to her involvement with a Church that preaches, teaches, and serves the ministry of The Gospel in addition to fellowship with other born-again Christians. Ann lives in Wayland with her husband Dennis and is blessed with two sons, a daughter in law, and three grandchildren.
