Travis MacPhee June 2024



My name is Travis MacPhee (he/him). I work as the Student Chaplain at Mt. Diablo Unitarian Universalist Church.

I am excited to support the MDUUC congregational and wider community with spiritual and emotional care. I feel that I have been spiraling towards spiritual care work for many years. I knew since I was young that I wanted to care for others, but spirituality was not something I opened up to until my mid-twenties. Before this opening, I felt too hopeless about the oppressive nature of the system into which I was born to anchor in any method of addressing it. I felt rudderless until a larger context of faith manifested itself in my life. With this new orientation, I felt called to join a Soto Zen monastery. Living for three years as a Buddhist monastic was deeply nourishing, and it helped me to ground my new spiritual perspective in a more balanced way. It also helped me develop means of mindfulness and meditation to more effectively and sustainably enact my calling for care.

I left the monastery looking not only to encourage greater peace and love, but also to contribute to the collective movement for justice. This calling to enact justice with spiritual care led me to enroll in the master of divinity program at Starr King School for the Ministry. It led me to work as an activist and organizer at JUUstice Washington, a Unitarian Universalist state action network in the state of Washington. And it led me to work in the streets of San Francisco’s Tenderloin and downtown San Rafael as a chaplain intern, caring for the houseless and housing insecure while learning about the structures and realities of economic injustice.

I am very glad that this calling has led me to Mt. Diablo UU Church. I hope to help in the movement for greater peace, love and justice that exists here. I hope to learn from each of you and to hold space for transformative healing through deep and caring listening. May our collaborative local efforts support collective transformation that reaches all beings with love.

Jen has extensive experience in project and event management, web development, and digital marketing that she wanted to bring back to MDUUC in 2017.  Although she graduated from St. John’s University with a BS in Toxicology, she started working in technical and event project management roles within a few years of graduating. She has 18 years of experience working for non-profit organizations and spent 9 years as an agency and freelance digital project manager/web developer/producer. She enjoys playing with her grandchildren, digital and watercolor painting, floral design, cooking, football, and hanging out with family in her spare time.




Ging’s blend of graphic arts design and marketing background spans the corporate realms of real estate, investing, and information technology, guiding her to MDUUC where she can contribute to a community focused on service rather than profit. Raised with Taoist and Animist beliefs, she is passionate about exploring diverse cultures, religions, and perspectives.

At home in Contra Costa County, she wrangles a lively crew: a husband, two kids, a dog named Appa Cabbage, a cat named Coco Banana, and some plants that could use some therapy. When she's not coaxing life out of her garden (fingers crossed!), she's rooting at her daughter's soccer game, grimacing at her son's tae kwon do sparring match, rescuing treasures from the roadside, and experimenting with watercolors, illustrations, and oil pastels.
