​​Mary Jane comes to the board from State College Presbyterian Church in State College, PA, where she is active as a spiritual companion and retreat leader. She’s also connected as a lay associate to the Community of Anawim in Frenchville, PA which she regularly visits for ongoing contemplative training and community. Her work is informed and fed by having trained through Oasis in both the Spiritual Direction for Spiritual Guides and Deepening Year Direction Ministries and through ongoing studies of the Enneagram as a tool for spiritual  transformation through the Enneagram Institute. She and her (recently-retired) husband raised 3 adult children and enjoy the rural gifts that central Pennsylvania has to offer through hiking, kayaking and skiing and golf.

​​The Reverend Paul W. Gennett Jr. returns to the Oasis board with joy – hopefully the staff and other board members feel the same way! Paul has served as a priest in the Episcopal Church for 24 years. He received a Masters in Divinity from Virginia Theological Seminary in Alexandria, Virginia, in 1992. He currently serves as Rector at St. Thomas’s Episcopal Church in Newark, Delaware. Paul’s deeper calling to the spiritual journey is a combination of first attending the SDSG course from 2001-2003. Paul is married to Marilyn and they have two adult children – son Colin and daughter Adrienne. Paul enjoys being a spiritual companion with others, a retreat leader for church and recovery from addiction programs, and is developing his gifts/interests in poetry reading/writing, hiking, many sports [enjoyed but not played very well at all], and renewed work in furniture care and refinishing.

Rachel is experienced in the operational structure of non-profits. She holds a Master’s of Divinity from Biblical Theological Seminary and is currently studying for a Doctorate of Theology at LaSalle University in Christian Spirituality with a focus on contemplation and mysticism. She is drawn to the beautiful mystery of God and realizes the need for humility within our theology. She is passionate about expressing the inclusive, life-giving gospel message that she has come to know in creative ways. Ultimately, Rachel desires to open others to the fullness of life that comes as we break away from our false sense of self and dualistic thinking commonly found in religion, journeying with them deeper into the abyss of God’s incomprehensible love!

She received her certification in Spiritual Direction from the Upper Room Spiritual Center in Neptune NJ in 2012.  Teresa practices Spiritual Direction in her home parish of St. Paul of Princeton where she taught religious education for 10 years and started the Prayer Shawl Ministry in 2005.

As a summa cum laude graduate from Muhlenberg College and graduate of The Dickinson School of Law, Angela has been practicing law for the past 30 years. Within the last 10 years, her focus has been to exclusively represent children with disabilities and their families with obtaining special education services from their schools.  As a mother of child with autism, she is most passionate about helping children with disabilities receive the help that they need to reach their potential and find their place in the world.  She and her husband of 30 years reside in Nazareth PA.  They have three children: a son who is working as a therapist and twin daughters who are in their first year of Law School.  As a Roman Catholic woman called to the priesthood, Angela's heart has long been drawn to all matters spiritual. Now that her children are grown, she has taken advantage of the opportunity to go back and discover what God's call means to her. She has been immersed in Franciscan spirituality and blessed to have completed the Spiritual Direction for Spiritual Guides two year program through Oasis Ministries. This program has been life changing for her and confirmed her desire to commit to the contemplative path.  Angela is also a member of the 2019 Cohort of Father Richard Rohr’s Living School.  She has just started a little ministry called “Magdalene’s Blessing” through which she hopes to grow her spiritual direction practice.  “Magdalene’s Blessing” is dedicated to inviting all to follow the spirit of Mary Magdalene in discovering the immensity of the love of God and growing into a deep and personal relationship with this wonderful God who is Love.

For a decade Tricia Brown-Nystrom has been creating safe spaces for people’s spiritual stories and highlighting how they intersect with God’s story. She believes in making the Holy attainable for everyone, every single day. She has helped people to expand their concepts of spirituality beyond the parameters of a Sunday experience. Years of speaking and writing on, deepening faith practices in a modern age, creativity, and intimacy at conferences and schools had left Tricia feeling she could do more to make spiritual direction accessible in the twenty-first century. Shepherding and art have long provided Tricia a connection to the Holy throughout her life. Her unique take on spiritual direction for both groups and private confidential one-on-one is designed to facilitate the same connection in people’s fast paced lives. Regardless of whether you are in a place of change or looking for it, Tricia Brown- Nystrom would be honored to sit alongside you in spiritual direction. Tricia lives on her farm in Hershey, PA with her herd of East Friesian Dairy sheep and her herd of 8 children alongside the man of her dreams, Ben. She enjoys painting, writing, obedient dogs, days without laundry and leading her home church into whatever God has for them. Tricia is completing her second year in SDSG.
