Ending homelessness? Combatting climate change? Connecting with underserved communities? Being involved in important domestic and global issues? Helping to minister to those in need in the congregation? Mental health? Here’s a look at some of the things we’re doing. You’re welcome to join us! 

Peace and Justice Commission

Peace and Justice (P&J) works to fight the root causes of injustice by  clarifying social issues and recommending the effective use of St. Mark resources. Activities include the non-partisan annual Great Decisions Foreign Policy series, Alternative Christmas Market, Bread for the World Offering to end hunger, working with immigration detainees, preventing human trafficking, and more.

Our Health Ministries Commission promotes wellness and health in all aspects of our lives (body, mind and spirit), and the Care Team, a Parish Nurse and Parish Counselor work together to support the needs of St. Mark members in their most vulnerable of moments. St. Mark is part of Hoag Health Ministries.

Care Team

These volunteers provide loving presence, prayer and concrete support when emergencies or illness affect our members. They send cards, visit members in home or hospital, prepare meals, give support during medical appointments, and coordinate transportation. For more information, contact Louise Van Buren

Parish Counseling

Gretchen Weisenburger Carillo, a Licensed Marriage and Family Therapist (LMFT), is a resource for members for support, information and education in the area of mental health and well-being. She meets with members and visitors, providing consultation, crisis support and linkage to referrals and resources. You can reach Gretchen by email to schedule a confidential appointment.


As Christians, we believe we have a moral obligation to care for the earth and our environment.

We demonstrate this on our own church campus, which was designed with energy-saving features and environmental sustainability in mind. We are certified as an Earth Care Congregation by the Presbyterian Church USA (PCUSA). We support organizations such as Presbyterians for Earth Care, the PCUSA Environmental Ministries, and the Orange County Interfaith Coalition for the Environment.



Besides our social justice activities, many of our members are involved in a variety of St. Mark committees, such as Membership, Marketing, Social Events, Facilities, Adult Discipleship & Nuture, and more.
