​​About Us

Who we are:​​

Oasis Ministries (Camp Hill, PA) is a 501(c)(3) non-profit corporation which offers ecumenical training programs in spiritual direction and contemplative prayer practices: deepening growth through spiritual companioning, day workshops, and retreat leadership.

Call (717) 737- 8222 or email [email protected] for more information.
Our Vision:

​Training programs offered through Oasis draw from the depths of Spirit revealed in many traditions, with the well of the contemplative Christian tradition providing the main source of the teachings. We offer retreat nourishment and educational programs steeped in the experience of community for persons seeking refreshment, deepening and growth for their lives of service to, and presence in the world.

Our Mission:

Oasis Ministries for Spiritual Development is a contemplative community that invites people to experience God in their daily lives. We do this by:
  • Providing training in spiritual direction
  • Educating in mindfulness and prayer practices
  • Offering day-long retreat opportunities and year-long programs and retreats for groups and communities
We all have had dryness and desert emptiness in our lives. Oasis, as the name implies, gives our mind, body, and soul a place to splash in the love of God that often gets buried with the busyness of our lives.

Angela Murphy
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.

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.

Tricia Brown-Nystrom
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.

Solitude, meditation
Living the question
Ahhhh, Oasis
~Marie Rodichok
You can support the VITAL PAUSE which Oasis Ministries provides through:

REMEMBERING Oasis, its leaders and participants, in your times of prayer and meditation

In many of our Oasis gatherings, a candle is lit...
a simple call to prayer, an invitation to center and focus. In many different traditions lighting candles is a sacred action. It expresses more than words can express. We wish to share sacred community, sacred space together even though we may not be geographically close. Knowing that you are held in prayer by the Oasis community, we invite you to light a candle.
You may want to begin or end your day by the sacred ritual of lighting a candle. Or you may want to light a birthday candle for a friend. You may wish to share a prayer request or offer a blessing.
Blessings on your journey..
