The practice

Owned by the physicians who work in it.

No hospital system and no private equity. Decisions about how we practice are made in the building by the physicians who see the patients, which is why the group has kept the same character across a generation of nephrologists.

Through Southeastern Clinical Research Institute, the research arm the practice founded more than 25 years ago, every one of our physicians is an investigator. The institute has conducted more than 200 studies for sponsors including Lilly, AstraZeneca, Bayer and Novo Nordisk, and our physicians are among the authors of the SPRINT, DAPA-CKD and vadadustat papers in the New England Journal of Medicine. Those trials ran in the same exam rooms where the patients were already being seen.

The result is a practice that spans the whole arc of kidney care: CKD clinics, hospital coverage, dialysis units directed by our physicians, transplant coordination, hypertension, and interventional nephrology, across a metro of 637,000 people and the rural counties around it.

For nephrology fellows

An investigator from year one, on the patients you see in clinic.

Most first jobs make you choose between practice and research. Here the nephrologist who sees a patient in clinic is the one who enrolls and follows them on protocol, with a coordinator team carrying the regulatory load. We practice medicine, and help write it.

  • ResearchFrom the first yearJoin protocols as a sub-investigator in your first year, attend the weekly research meeting, and see study patients in a dedicated research clinic. Studies enrolling now are listed at /scri/studies.
  • PartnershipPhysician-ownedA track to ownership in a physician-owned group, with dialysis medical directorships and the research institute as part of the picture. Base, guarantee, incentives and the timeline go in writing before a visit.
  • StandingCredentials in the groupFellows of the American Society of Nephrology and the American College of Physicians; certifications in clinical hypertension (ASH) and interventional nephrology (ASDIN); NEJM authorship; faculty appointments at the Medical College of Georgia.

In their words

Why the physicians stayed.

I trained in the Air Force and came home to Augusta to practice. What kept me here is a group that owns its own decisions, and a research institute we built so our patients would be first in line for what comes next.

I left a professorship at the Medical College of Georgia to run research inside a practice. The science is the same. The difference is that the patient in the trial is a patient one of us has known for years.

At Walter Reed you learn to run a service. Here I direct two dialysis centers and sit on protocols in the same week. Nobody asked me to choose between the two.

Life in Augusta

A river city with a medical college, and room to live.

Augusta is the second-largest metro in Georgia, on the Savannah River at the South Carolina line: home to the Medical College of Georgia, to Fort Eisenhower and the Army's Cyber Center of Excellence, and each April to the Masters. Physicians who move here tend to say the same two things: the cost of living, and how close everything else is.

Downtown Augusta, where our Greene Street office sits, is on the river and the Augusta Canal, a few blocks from the Medical College of Georgia. Evans and Columbia County, ten minutes west, are where many of our physicians live. Ask any of us about schools, neighborhoods and the commute.

White paper

We practice medicine, and help write it: what integrated research looks like inside a physician-owned nephrology practice.

How a ten-physician group runs 200+ clinical trials in its own clinics, what that does for patients, and what it does for a physician's career. With the questions to ask any practice about its research.
