Carmen Horst Okanya, Lead Pastor    chorst@jsmchurch.org

Carmen originally came on board in June 2011 as Associate Pastor, becoming JSMC’s Lead Pastor in June 2025. When she isn’t working on a sermon or giving pastoral care, you can find Carmen reading at home or trying out one of Lancaster’s fabulous restaurants. Carmen is married to Dr. Nelson Okanya. Together they parent Barak and Izak.

Jenny Gehman, Associate Pastor    jgehman@jsmchurch.org

Jenny Gehman is an author and spiritual director. When she and her husband Dan were married in 1989, JSMC (then named Charlotte Street Mennonite Church), was their first church home. After leaving to help with a church plant, and serving in a number of other congregations, it was their joy to return to their home here in 2023. Jenny and Dan spent their lives in a ministry of hospitality to international students. It is her joy to bring her skills of communication, community building, and cultivating creative practices to nurture the spiritual life in our congregation. Jenny and Dan are parents to one adult son (Ryan). Their favorite place to be found is deep in the woods — preferably with tea, a hammock, and a few good books.
