Kathleen Ellerston

I am the daughter of an Army Air Force, WWII bronze star recipient, who was also an artist. Due to his horrific D Day experiences, my father suffered from unspoken PTSD resulting in alcoholism.  He did not talk about his war experience. But we knew something was wrong.  I escaped – got a degree in Art History, studied in Italy, got married, had two kids and got divorced.

In 2009 my dad died and my internal battles resurged. This time I faced them head on.  I knew I wanted to do something to honor my dad’s service but also help Veterans with PTSD.  It hit me that we do NOT offer many Veterans the care they deserve. I knew about the healing properties of art. Still working full time, I volunteered for several Veteran artists groups to share their art journeys in art shows.

This inspired to create my own non-profit online gallery where Veterans can share their stories and their art. Giving back to the Veteran community in this way has proven to be more fulfilling than I ever hoped and now it’s my life work.  With my fine arts knowledge, and the help of veterans and friends thereof, I created the Veteran Art Institute.  I am honored to share their work with the Interfaith Peace Project.

He has helped found a number of faith-based environmental and social justice organizations in the Bay Area and is active in interfaith work in the San Ramon Valley.

Upon returning to the United States, Rabbi Dan produced a weekly Jewish television show before he and his wife Yael moved out to the Bay Area in 1981. Rabbi Dan was an award winning writer/director/producer of documentary films, a number of which were aired on the Disney and Discovery Channels. He was a professional theater director and spent a year as a guest artist in the theater department at UC Berkeley. Prior to coming to Beth Chaim, Rabbi Dan served a number of synagogues from Vallejo to Davis as part-time spiritual leader.

Sr. Trinita Laffan, PBVM

Trinita (2)Sr. Trinita Laffan is a member of the Presentation Sisters of the Blessed Virgin Mary in Portlaoise, Co. Laois, Ireland. She was born into a farming family with six siblings, so that enjoying and respecting mother earth was second nature to her. After 30 years as a teacher, she felt called by the Spirit to seek out people at the margins of society This led to working with ex-prison offenders and young at-risk men in a poor suburban area of Cork. It was both challenging and a huge learning experience. Then, after 12 years in Provincial Leadership, she took a sabbatical in 2015, focusing on world religions with an emphasis on interfaith and interspirituality. This time included 10 weeks in India, a semester at the School of Applied Theology in Berkeley, California, and considerable reading and reflection in these areas. Both enthused and energised by her experience, she joined the team in Mount St. Anne’s Retreat and Conference Centre in Portlaoise, Co. Laois, Ireland. She is excited by this newest ministerial opportunity and also by the fact that a genuine search for spirituality seems to be emerging among Irish people in place of the sometimes mindless inherited religious practice. Sr. Trinita: “It seems to me that we are trying to recover core human and religious values in a multicultural Ireland that is utterly changed from the one in which I grew up. To quote our poet William Butler Yeats: ‘All’s changed, changed utterly. A terrible beauty is born.’ Perhaps the ‘terrible beauty’ is waiting to be born!”

Channing Miller

Channing enthusiastically looks forward to beginning her role on the Advisory Board of the Interfaith Peace Project.  In 2017 Channing became a seminary student at the Chaplaincy Institute Interfaith Seminary and Community in Berkeley, CA and will be ordained into Interfaith Ministry in 2019.  She also will begin the Spiritual Direction program at the Chaplaincy Institute in 2019 and be certified as an Interfaith Spiritual Director in 2020.  In addition to expanded knowledge of religion, culture and spirituality, key values and emphasis include the importance of deep listening, compassion, honoring differences and the human spirit, being present, continuing spiritual study and practice, love and hearkening to the invisible as well as the innermost and outermost edges of being.

Lifetime professional experience began in 1968 with teaching young children in Palo Alto and culminated in 2015 with a long career in global corporate communications.  Channing’s combined education and corporate careers have spanned two coasts and over four decades.  In 2015 after retiring fully from the corporate world, a move from Silicon Valley to the Rossmoor community in Walnut Creek allowed the hearkening of spiritual yearnings where a call was felt and received, and a discernment towards the next path in interfaith studies, ministry and spiritual direction became visible.  Bringing teaching, collaboration, creativity, facilitation, and deep heart abilities to interfaith ministry and spiritual direction is a blessing.  Having written a series of children’s books on “Conversations in Nature” with the themes of interconnection, interdependence and gratitude, Channing is currently piloting these in schools throughout the east bay, looking towards one part of her ministry being to young children through literature and creative expression.  Her spiritual journey continues towards “inter-spirituality” which began in childhood and will continue for the rest of life.

Currently in addition to attending The Chaplaincy Institute Interfaith Seminary and Community, Channing is a member of two Interfaith Councils – the Interfaith Council of Rossmoor ( and as an elected member of the Interfaith Council of Contra Costa County ( She serves and supports existing programs, and has also initiated and supports new programs to help expand interfaith dialogue, consciousness and relationship within these communities. Life passions include nature, beauty, social justice, working with children and youth, creative (multi-media) and writing expression (poetry and children’s books), and her relationship with her beloved adult children and grancchildren.
