OUR MISSION
Extend compassionate, comprehensive healthcare in a Christian environment to individuals in need throughout the Mountain Empire regardless of race, creed, color, gender, religious affiliation, or ability to pay. We render this care to uninsured and underinsured individuals with the hope that individuals will be healthier, and communities will be strengthened.
STAFF
Drs. Paul and Tim have been involved in Crossroads from its infancy, and grew out of their perception that many people were unable to access basic primary medical care. The mission's success for reaching the underserved has far exceed their expectations. They will be forever thankful and in awe of the support that the mission has received from the local community over the years.
