Jillian Diffenderfer was born in Lebanon, PA and is currently a resident of Maytown, a small town in Lancaster County, Pennsylvania. Jill and her husband Karl have four beautiful children, one daughter-in-law, and one grandchild. The Agape Gardens of Servant’s Oasis hold special meaning for Jill, as she and her husband renewed their vows at the property when it was originally the Gardens of Felicita.

Jill first learned about Servant’s Oasis when it was in its fledgling stages, and reconnected with Servant’s shortly after the passing of her father, who was a good friend of Roy Smith’s. Having witnessed the devastation and fall-out of ministry leaders who burn out or stumble first-hand, and having experienced it herself, Jill is devoted to Servant’s Oasis’ mission of serving the leaders who serve others.

In 2023, Jill joined the Board of Directors, contributing her extensive marketing experience, attention to detail, compassion, and enthusiasm to aid in our mission. In March 2024, Jill accepted the position of Administrative Director of Servant’s Oasis, expanding our fundraising efforts and supporting day-to-day operations.

Wilmer has been a member of the Servant’s Oasis Board of Directors for 8 years and is currently serving as the Chairman of the Board. He was asked to join the board to work on the building plan for the retreat center due to his extensive background in real estate and land development.

After finishing high school, Wilmer worked for his father’s floorcovering business, eventually taking over, then passing management on to his own son. During this time, Wilmer also worked in real estate sales, and eventually took on a regional management position until he opened his own real estate office in 1990. He officially retired in 2003.

Wilmer and his wife Shirley reside in Leola, PA, and attend Harvest Bible Church in Eden. They had two sons, of which one went to be with the Lord at the young age of 21. They have three grandchildren and three great grandchildren. Wilmer enjoys golfing, spending time with his great grandchildren, and enjoying nature at his mountain home in Fulton County.
