Joshua “Mountain” Armstrong, is a Florida native with a profound love for nature and gardening. Rooted in his faith and academic pursuits in Philosophy and Religion, Joshua is an avid reader and a lifelong learner.

Joshua’s journey began with a deep passion for the outdoors, earning him the nickname “Mountain” due to his unwavering determination, resilience, and rugged appearance. He founded a successful landscaping company, where he transformed ordinary spaces into breathtaking landscapes, and served as a superintendent with the largest custom home builder in Central Florida. His love for nature, commitment to his faith, and dedication to lifelong learning have created a unique blend of talents and passions, making him a valuable contributor in making the vision of Servant’s Oasis a reality.

After heartfelt reflection and prayer, Joshua relocated to Pennsylvania to become the Director of Servant’s Oasis. In this role, he intends to care for the physical needs of the community as well as their spiritual well-being, driven by a desire to make a lasting impact for God’s Kingdom.

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.
