Third River Medical Expands to Oxford, Adding Physician-Led Wound Care Services

Walk-in patients who knew the Oxford clinic as OneCare Medical arrived this week to a new name, a broader network, and a general surgeon on staff. Third River Medical, the Southaven-based medical group specializing in vascular care and wound healing, folded the clinic into its regional network on March 31, rebranding it as Third River Medical Oxford and adding physician-led wound care under General Surgeon Donald H. Parnell, Jr., M.D.

Dr. Parnell brings more than a decade of wound care experience to the Oxford practice, overseeing treatment for complex wounds, diabetes-related complications, and chronic injuries that previously required patients to seek specialty care outside Lafayette County. Urgent care and family medicine services, already the backbone of the clinic's walk-in volume, continue without interruption.

For Third River Medical founder David Barham, the move north from Southaven is both clinical strategy and personal mission. His own experience managing diabetes shaped the organization's focus on timely, minimally invasive treatments designed to prevent the long-term consequences of poorly managed wounds, including amputation. The Oxford expansion is part of a stated broader push to reach more patients across North Mississippi.

Dr. Parnell described his approach in two ways that set expectations for how the clinic intends to deliver on that mission. On communication: he said clear, plain-language explanations help patients become "more invested in the care of themselves," treating patient education as a clinical tool rather than a courtesy. On team structure: drawing on his background in collegiate coaching, he described the clinic's model as collaborative and role-focused, with contributions welcomed from every level of staff.

On insurance, Third River Medical accepts both in-network and out-of-network plans and works directly with insurers to clarify coverage before treatment, a departure from the out-of-pocket uncertainty that often accompanies specialty referrals. Patients managing chronic wounds or carrying existing wound care referrals can now pursue treatment locally rather than routing to Tupelo or Memphis. Specific appointment scheduling timelines for wound care have not been published; patients should contact Third River Medical Oxford directly to confirm availability.

The clinic's integration into a network already operating amputation-prevention and endovascular programs in Southaven gives the Oxford location a clinical depth that OneCare Medical, as a stand-alone urgent care, did not carry. Whether that depth reaches patients who need it most will depend on how quickly Dr. Parnell's wound care services become known to the referring physicians and home health providers already working with Lafayette County's diabetic and vascular patients.
