About GCC

Established in 2004 as a faith-based, not-for-profit organization, GCC (formerly FCSC) seeks to provide free medical and counseling care to our underserved neighbors in the metropolitan DC area. Our clinic is run entirely by volunteers and operates using our donors’ personal and corporate contributions. We operate on Sundays and provide an array of services, including internal medicine and pediatrics, dentistry, and cardiology.

GCC believes in the holistic betterment of our patients’ health. In addition to medical treatment, we seek to provide our patients with emotional and spiritual support as well. As such, GCC offers counseling services to our community through the Washington Christian Counseling Institute (WCCI). A faith-based counseling arm, WCCI is run by professional counselors and social workers. GCC medical experts and WCCI’s counselors work in cooperation to restore our patients’ minds and bodies.

Through our multi-generational cohort of volunteers, we mentor, nurture, and equip our future generation of servant-leaders with confidence, humility, and a generous heart attuned to the needs of their community.

GCC does not officially advertise its existence; word-of -mouth referrals bring both patients and volunteers to our organization. By Providence, the organization has beautifully flourished, with a staff providing a full range of services to patients of diverse backgrounds. We offer interpreting in Spanish, Arabic, Hindi, Telugu, and Korean.

We are grateful for the encouragement and support from our many donors, and with eager hearts await the Lord’s provision and blessings in the years to come.

Staff & Volunteers

GCC is blessed to have a family of volunteers with diverse backgrounds and expertise. The unique talents of each individual, combined with their compassionate hearts and desire to share their blessings with the community, sustain GCC’s operations and enhance its potential to serve as a channel of blessing to our communities.

We hope that our volunteers will challenge and inspire you to donate your time, gifts, and resources to our clinic’s activities.
