Mary Beth Mardis-LeCroy, Pastor

Rev. Mary Beth Mardis-LeCroy

Pastor & Head of Staff

Pastor Mary Beth loves being the pastor at Old Greenwich Presbyterian Church, a church where true hospitality, founded in Christ’s own welcome, is extended to all people.  In a world where tall walls of suspicion so often separate us from our neighbors, Pastor Mary Beth believes with every ounce of her being that the church must hold forth the promise of a genuinely welcoming, genuinely reconciling community. She is grateful every day to share this vision with Old Greenwich.

Mary Beth grew up mostly in South Carolina, but attended schools in the Northeast (BA from Yale University and M. Div from Princeton Theological Seminary). Before landing in New Jersey in January of 2020, Mary Beth served as associate pastor at Westminster Presbyterian Church in Des Moines, IA for 3 years; and as pastor at St. Paul’s United Church of Christ in Madrid, IA for 10 years. She worked as a hospice chaplain at Hospice of Central Iowa for 2 years between her two pastoral calls, and directed a bluegrass/gospel band for the Saturday evening service at Plymouth Church in Des Moines “on the side” for well over a decade while in Iowa.  

She and her husband Matt (also a Presbyterian pastor!) have three children: Ellie, Wil and Calvin, and one cat, Abelard. Mary Beth enjoys spending time with her family, attempting to play music of all kinds, walking or jogging (let’s be honest, walking), praying with monks, and seeking out the best cannoli in the Lehigh Valley.

Harry and Joan Pursel

Harry & Joan Pursel

Sextons

Joan grew up as a true farm girl in SW North Dakota. Harry grew up in Phillipsburg, NJ, and attended college at North Dakota State University, and that is where they met! Following Harry’s military Army service of 18 months in Germany (the best honeymoon ever) they returned to Phillipsburg and made roots in this area.

Harry and Joan have three children: Sonda, Darren and Kyle. Sonda, Craig and daughters, Sydney and Leah, live in North Carolina; Darren, Mia, Elizabeth and Ryan live in Texas; and Kyle, Lauren and daughters, Elli and Morgan, live in Virginia. What great places to visit! Harry and Joan are looking forward to many more visits with family.

The Pursels are retired but are not ready to be idle! Their sexton job is to maintain the church and the church property. Joan and Harry like to say that the job also gives them things they like to do: ride a tractor, mow grass, garden, cook and bake, attend events and enjoy extra socialization.
