About Us

A Ministry of Healing

Through the Lord all things are possible. The sick can be healed, souls can be saved, lives can be fulfilled, and it can all begin with your help. Within each one of us is the power to change hearts, minds and the world for the better. Great Commission Outreach is a partnership of believers on a global mission to spread God’s word by helping others in need. With a focus on medical outreach, we provide hope through healing, success through sacrifice, and faith through friendship to gain a better understanding of what it truly means to serve.

What We Do

When faith forward individuals band together to make a difference the world becomes a better place and, somewhere along the way, all of our lives are changed.

What began as a local endeavor to provide healthcare and stewardship to neglected individuals in the community has grown into a mission to improve the quality of life for people around the world. The Outreach focuses initially on providing primary healthcare, but through the strength and wisdom of our physician-volunteers, we will address such areas as mental health, family relationships and other social issues.

“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”  

Matthew 28:19-20 (NIV)
