Our mission is to 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.


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.

Cindy  Rockett

Executive Director

Her license plate reads “Rockett Power” which may be only a slight exaggeration.  Cindy Rockett is unable to leap buildings in a single bound, but she IS able to drive a 43’ mobile medical clinic through the mountains of Virginia and Tennessee!

As the original and only executive director of Crossroads Medical Mission, the “Doctors’ Office on Wheels,” Cindy was named Health Care Community Hero by the Tri-Cities Business Journal and was featured in the Tri-Cities Emerging Power Series by the Bristol Herald Courier, in which they “spotlighted some of the most energetic, hardworking, influential and successful women in all areas of life across the Mountain Empire.” Cindy’s recent Master’s degree capstone project focused upon building social capital in the Mountain Empire through Crossroads Medical Mission’s corps of volunteers.


Cindy’s leadership has brought Crossroads Medical Mission from the financial abyss of having less than two month’s operating funds to a point of ongoing sustainability.  She is hands-on in her approach with volunteers, patients and contributors alike.  Proud of the staff, volunteers and the communities in which Crossroads Medical Mission provides health care services, Cindy plans to continue with the unique approach to providing health care to folks in need.
