Dr. McColl launched the Trinity Direct Primary Care program January 1st, 2016 and opened the doors to the Hardin Valley office on September 19th, 2016 to serve the communities of Hardin Valley, Karns, Solway, Oak Ridge, and West Knoxville.  Originally a 1200 sqft house built nearly 30 years ago, this office has been transformed to be a state of the art medical office without losing the home like qualities. January 2020 Dr. McColl transitioned the TDPC program in to a solo, independent practice in order to continue providing unparalleled, personalized service to his patients and the community.

Dr. Mark B McColl, board certified in both Internal Medicine and Pediatrics, staffs this office along with his nurse and the DPC coordinator.  Dr. McColl cares for newborns to the elderly.  At one time in his practice, he had both the newest patient, a newborn, and the oldest, a decagenarian (a person over 100 years old).  He especially enjoys caring for entire families and their multiple generations.

Truly, primary care has returned to its roots of caring for patients in a warm and inviting setting.  Doctors of old would invite their patients into their homes for care.  Today, patients and doctors alike can share a space as one community.

With a vision for the future this office was renovated with expansion in mind.  It has the capacity to add another full time physician and nurse which will further expand the services offered.
